Abstract
Currently, leather industries of Bangladesh are facing considerable amount of pressure to
adoption of sustainable supply chain management practices in traditional supply chain
network. The approach of incorporating sustainable supply chain management practices in
the traditional supply chain is becoming greatly important for the industry due to
environmental awareness, competitiveness, and government environmental policies. Hence,
SSCM implementation is a good practice of sustainable development in the competitive
world market due to its consideration for environmental, social and economic issues. There
are many barriers for adopting SSCM into leather processing industry of Bangladesh, but
these barriers do not ensure similar impact for all industrial sector and countries. To bridge
this gap, it is a crucial issue to identify most influential barriers to adopting SSCM practices.
In order to implement SSCM practices, a careful analysis of the most common barriers that
obstruct the whole process must be identified.
In this study, a numerous 35 barriers of SSCM implementation are identified through detailed
literature review and deeper survey on leather processing industry. Most common 20 barriers
are selected with the help of industrial and academic experts for the analysis of the cause-
effect and prominence relationship among them. The main contribution of this study is to
identify the key barriers and find out the cause-effect relationship among barriers to the
implementation of SSCM in the leather processing industry of Bangladesh by using a blended
grey based DEMATEL approach. The results of the thesis aim to support the leather
processing industry in a way that the industrial manager can identify most influential barriers
and this emerges as the crucial part of eradicating barriers. The results show that the ‗Lack of
awareness of local customers in green products‘ and ‗Lack of commitment from top
management‘ seem to be of greater priority in the casual group. Cause–effect relationship is
plotted to facilitate decision maker to identify casual barriers that need attention during
SSCM implementation in the traditional leather supply chain.

Chapter 1
Introduction
1.1 Introduction
Supply chain management (SCM) is the management of a supply chain network
of interconnected businesses involved in the final destination of product and service
packages required by end customers (Harland, 1996). It represents the coordination of key
business processes among industry partners to maximize value for the end customers
(Janvier-James, 2011). SCM plays a key role in the sustainable development of
manufacturing industry. It is an integrated process to maximize the profit of industry. The
rapid development of any industrial sector requires an increase of supply chain activities
(Holweg and Pil, 2008). Such increase of supply chain activities is an important issue in
the deterioration of natural resources, waste generation, water pollutions, harmful emission
of various gas and disruptions in the eco-system. To minimize the environmental
depletion, sustainable supply chain management practices help to integrate the
environmental management practices with supply chain management in order to prevent
the environmental degradation or to preserve so that further degradation is not allowed
(Diabat and Govindan, 2011). Therefore, sustainable supply chain management practices
have been a popular 21st-century trend among different industrial activities such as food
packaging (Smith, 2008), mining (Ting et al., 2014). Thus, today‘s business fields of
developed countries are facing competitive regulatory and social pressures for adopting
sustainable supply chain practices. Recent studies on sustainable supply chain management
practices show the pressures from government, stakeholder and customer to effectively
adopt sustainability issues into their supply chain network (Seuring and Müller, 2008).
2
Sustainable supply chain management helps to minimize or eliminate waste in all
forms including harmful gas emission, waste minimization, water pollutions, soil
pollutions, solid waste reductions. Majority of supply chain management innovations in
the 20th century aimed to the reduction of waste for economic purpose rather than
protection of the environment but the 21st century aims at reduction of waste for protection
of the environment (Pagell and Wu, 2009; Seuring and Müller, 2008; Walker and Jones,
2012; Zailani et al., 2012). Recent researches show that in the next couple of decades, most
of the Asian manufacturer will face environmental issues. In the context of Bangladesh for
leather processing factory, considering an environmental sustainable point of view,
traditional supply chain management needs to be modified sustainable supply chain
management. Various organizations of developed countries adopt manifold environmental
management strategies such as adoption of cleaner technology (Grutter and Egler, 2004),
ISO 14001 certifications (Nawrocka, 2008), and environmental management systems to
minimize the adverse environmental effect of their supply chain (Nawrocka et al., 2009).
During the adoption of sustainable supply chain management in traditional supply chain
management, some barriers can be an obstacle the whole system of the supply chain
(Sajjad et al., 2015). It is important to eradicate barriers to implementing sustainable
supply chain management practices in industrial fields. However, it is not possible to erase
all barriers simultaneously. Hereafter industries should identify and analysis those barriers
which have to be essentially removed during the adoption of sustainable supply chain
implementation.
The goal of this study is the identification and analysis of multiple barriers through
the grey based DEMATEL approach so that an industry might be minimizing the effect of
barriers to sustainable supply chain implementation. This study addresses two-phased
research which includes research methodology: an initial survey to identify major barriers
from existing literature review and deeper analysis of leather processing factory, and
solution methodology: identifications of common barriers and to find out most influential
barriers relevant to leather processing factory from the feedback of industry experts and
academic expert with the help of grey based DEMATEL approach. Barriers of the
sustainable supply chain are interlinked to other barriers. One barrier to adoption of
sustainable supply chain management practices has direct influence to the other barriers
3
(Xia et al., 2015). In order to effectively quantify the most common barriers to adoption of
SSCM practices, they should be ranked on basis of overall influence over other common
barriers. This study helps to find the cause-effect relation among other barriers to adopt
SSCM practices in the leather industry. Twenty barriers are identified to the adoption of
SSCM practices in the case of leather processing factory. After the study is conducted
casual relations of different barriers are plotted into digraph for prioritizing rank among
them.
Literature reveals that there is no work on analyzing and quantifying barriers to
sustainable supply chain management implementation in the context of leather industry of
Bangladesh. Even though, there are some studies on the sustainable development of other
fields (Ahmed et al., 2014; Azad et al., 2009; Biswas et al., 2004; Hossain et al., 2007;
Roy, 2013). Leather sector is a rising industrial sector of Bangladesh but till now no
research on it for sustainable development of Bangladesh. Thus, this study attempts to fill
this research gap in the sustainable supply chain literature with the help of grey-
DEMATEL approach. The major contribution of this study is identification and analyzing
of common barriers to adoption of sustainable supply chain management practices in the
leather field. During the implementation of sustainable supply chain management
practices, it is necessary to quantify the most influential barriers. A grey based DEMATEL
approach has been used in this thesis to effectively quantify the most influential barriers
among various common barriers. To realize this framework, a real life case study on
leather processing factory is also introduced.
1.2 Objectives of the Thesis

Literature Review
2.1 Supply Chain Management
A supply chain is a dynamic activity and involves the constant flow of materials,
information, and funds. Therefore, supply chain management is the management of
materials, information, and funds as they move in a process from supplier to manufacturer
to wholesaler to retailer to consumer. Supply chain management involves coordinating and
integrating these flows among different companies (Chopra and Meindl, 2014). Supply
chain management helps to increase the profit of an organization as well as proper
utilization of resources. The main objective of supply chain management is to maximize
the profit of an industry. Hence supply chain success depends on the overall profitability of
a supply chain. Successful supply chain requires many decisions relating the decision of
flow of materials, information, and funds. Therefore, supply chain management helps to
manage such kinds of thing. Over the past decade, the traditional purchasing and logistics
functions have evolved into a broader strategic approach to materials and distribution
management known as supply chain management (Choon Tan, 2001). It is proved that
supply chain and supply chain management have played an important role in the business
efficiency and have attracted the attention of numerous academicians over the last few
years (Janvier-James, 2011). Supply chain management activity is the root of maximizing
profit of any kinds of industrial fields as well as service organizations. Therefore, it is
necessary to improve the supply chain management activities for the successful business.

2.2 Sustainable Supply Chain Management
Bangladesh is a developing country having a trend to increase economic growth
without considering the environment for increasing the production rates. The rapid
economic development and an over population destroy natural resources by polluting
water, air, and soil etc. (Hoque and Clarke, 2013). Hence, it is important to develop a
sustainable manufacturing framework in such a way that environmental depletion should
be minimized (Diabat and Govindan, 2011). Sustainable supply chain management is the
management of environmental, economic and social impacts and encouragement of good
manufacturing practices throughout the lifecycle of products. It helps to link development
and environmental issues and to force political and economic change locally, nationally,
and globally to overcome the problems (Zailani et al., 2012). SSCM is being achieved in
traditional supply chain management by considering the environmental, economic, and
social issue (Preuss, 2009). SSCM practices help to impart sustainable development of a
country which is the development that meets the needs of the present without
compromising the ability of future generations to meet their own needs (Paper, 2012). Eco-
friendly and cleaner technologies have played an important role in the leather industry for
sustainable development of the leather sector of Bangladesh. Hence, the implementation of
sustainable supply chain management practices in the leather industry of Bangladesh will
become one of the dominating factors for the survival of leather industry and its product
leather in near future. It is difficult to maintain a balance between human needs and
development without hampering resources. This study helps to develop a sustainable
supply chain framework by identifying and analyzing common barriers which are relevant
to leather processing factory of Bangladesh. Hence, these study will help to minimize
environmental degradation in such a way that the newly developed industry can consider
these barriers for starting their new business and also existing industry can convert their
traditional system to sustainable system.
Sustainable supply chain management practices are of top most concern for recent
world due to government regulation, customer expectation and the pressure imposed on the
buyer (Linton et al., 2007). SSCM, a cross-disciplinary field, has been growing popularity
both in industry and practitioners (Sarkis et al., 2011). Sustainable development is a
7
pattern of resource use that aims to human needs while protecting the natural resource so
that these needs cannot be met only for present but also for future (Kates et al., 2005). The
most adopted definition of sustainability is that of the Brundtland commission
―development that meets the needs of the present without compromising the ability of
future generation to meet their needs‖ (WCED, 1987, p.20 ; Paper 2012). The literature on
SSCM is still on the budding stage. Carter and Rogers (2008) mentioned sustainability is a
concept to gain long-term economic benefits by key integration of environmental, social,
and economic factors. Many researchers have indicated SSCM as an integrated approach
for minimizing ecological degradation (Esfahbodi et al., 2016; Harms, 2011).
Sustainability has become a popular global concern and hence motivated industrial
organizations are modifying their supply chain activities taking into consideration the
environmental, social and as well as economic impacts of their supply chains network
(Carter and Easton, 2011; Carter and Rogers, 2008). Sustainability is taken into
consideration by legislation, public awareness, and competitive opportunity. Sustainable
development is the better solution of reducing waste by proper utilization of the resource.
From this point of view, sustainable supply chain management is an activity that helps to
modify traditional supply chain. This modification turns to the sustainable development of
an organization. A truly sustainable organization can simultaneously achieve social,
environmental and economic benefits.
A wide range of issues like supply chain risk mitigation, greening in the supply
chain have to be incorporated in sustainable supply chain management. Along with this,
sustainable supply chain management approach includes product safety and performance,
protecting the environment, ensuring good governance thus making Bangladesh a good
place to work and live. The target of sustainable supply chain reduce is to reduce energy
consumption from operations, increase renewable energy use, reduce water consumption,
reduce hazardous waste generation, reduce environmental impacts from manufacturing etc
(Jayant and Azhar, 2014; Rauer and Kaufmann, 2015; Walker et al., 2008). As in
Bangladeshi leather industries, sustainability of supply chain is not maintained in
operational procedures due to the lack of proper law implementation or lack of proper law
existence. Also, scientific research and knowledge will definitely help private industries to
adopt the operational procedures to ensure SSCM and also to motivate government to
8
implement SSCM law to ensure sustainability. Operational implementation of SSCM in
industries should be a part of compliance maintenance as per International Standard
Organization. Along with supply chain, sustainability is also described as the potential to
reduce long term supply chain risks associated with resource depletion, population and
waste management (Govindan et al., 2014). During recent time, the micro-economic
application has been investigated in the field of engineering, operation, and supply chain
(Sarkis, 2012). In most of the case sustainability has described as ecological sustainability
with a little recognition of social and economic responsibilities (Maloni and Brown, 2006).
And almost all research conducted up to now has been done focusing on developed
countries (Zaabi et al., 2013). No research has been made in respect of Bangladeshi
context. Thinking about the adverse effect of the environment, top priority should be given
to maintaining and implementing sustainable supply chain to ensure a developed
infrastructure for the future generation of developing countries.
2.3 Overview of Leather Sector of Bangladesh
The government of Bangladesh has indicated leather sector as one of the most
growth and investment potential (ranked 5th) in the export earning sector (Paul et al.,
2013). Due to its high esteem expansion and less expensive work openings; the leather
sector has already been pronounced a thrust sector of the country. As of now Bangladesh
delivers and fares quality bovine and ovine, caprine (wild ox and bovine; sheep and goat)
leather that have a decent nearby and global notoriety for quality skins (Paul et al., 2013).
With export of quality leather, Bangladesh also export a huge amount of leather goods like
ladies bag, backpack, wallet, belts, travel bag etc. and leather footwear to developed
countries like Chaina, France, Italy, Germany, USA, UK, Japan, Spain, UAE ( Technical
Report, 2013). The entire leather sector of Bangladesh meets only 0.5% of the world‘s
leather demand which worth is USD 75 billion (Paul et al., 2013).
In Bangladesh, approximately 187 tanneries are located in the Hazaribagh area of
Dhaka that produces 180 million square feet of hides and skins per year (Technical Report,
2013). The supply-cycle of raw skins and hides 40-45% of the annual supply available
during the festival of Eid-ul-Azha, which is the major source of producing quality leather.
9
However, only about 40 tanneries are utilizing a major portion of their installed capacity
indicating ―sickness‖ existing in the sub-sector. This leather sector has a long established
tanning industry which produces around 1.13% of the world‘s leather from a local supply
of raw hides and skins ( Technical Report, 2013). Most of the tanneries of Bangladesh do
not have proper effluent treatment plants and every day those tanneries generate 20,000m3
of tannery effluent and 232 tones of solid waste. This effluent and solid waste are one of
critical issue for sustainable manufacturing practices in the leather industry. To minimize
this critical issue, specific cleaner technologies are required to adoption of sustainable
supply chain management practices in leather industries of Bangladesh ( Technical Report,
2013).
A newly established leather zone is expected to bring a clear conversion to the
leather industry with increasing green production, product diversification and new product
systems with increasing manufacturing sustainability of the sector. Sustainable
manufacturing practices and cleaner production will be a key issue for the development
nation destroying the environment. The leather sector of Bangladesh requires sustainable
manufacturing practices to achieve international standards in technical, environmental,
safety, and commercial aspects, and to attain competitiveness in the world market.
In addition to 2500 small footwear manufacturer, there are 30 modern shoe
manufacturers in Bangladesh, which produces quality footwear and export to developed
countries. The footwear sector is a top value added sector which earned revenues in an
amount of USD 483.81 million during 2014-15 fiscal years whereas leather sub-sector
earned revenues in excess of USD 397.54 million during 2014-15.
.
Leather goods sector is another rising sector as even, without large investment
could possibly to build industry. Besides, 3,500 MSMEs there are around 100 small-to-
medium leather goods manufacturers and a small number of larger manufacturers (
Technical Report, 2013). The leather goods manufacturing sector is ideal for young
people, women and micro entrepreneurs to start off in, based on the volume of start-up
costs and low capital investment. Leather goods manufacturing sector can also offer the
10
opportunity to achieve industrial experience and helps to transform to footwear or other
sub-sector. The leather goods sector earned revenue USD 249.16 million during the fiscal
year of 2014-15. The entire sector directly employs approximately 850,000 people. 53% of
the workforces are ladies in the leather and footwear ventures of Bangladesh.

2.4 Barriers to Sustainable Supply Chain Management
There are lots of barriers to adoption of sustainable supply chain management
practices in the traditional supply chain. In the context of Bangladesh, it is necessary to
identify barriers to implementing sustainable supply chain management practices,
especially for leather processing factory. In this section, this thesis shows the discussion on
most common barriers of sustainable manufacturing practices context of leather processing
factory of Bangladesh.
In the category of environment, plenty of barriers are present in Bangladesh. Strict
environmental regulations and reduction raw material resources have given importance to
SSCM implementation (Richey et al., 2005). Lack of Eco-Literacy amongst supply chain
partner is one of them. Lack of eco-literature in leather supply chain is the most important
barriers. Supply chain partner not have deeper knowledge about sustainable manufacturing
practice. Eco-literacy means the expertise understanding of the workforce resulting in
proactive responses when tackling environmental issues, rather than reactive responses. In
many of the research take this barrier for their research work. Lack of environmental
requirement, lack of practice on reverse logistics, lack of awareness of local customers in
the green product are the most common barriers in respect to environmental issues. In
Bangladesh, sustainable supply chain management is not practiced in structured ways in
12
any leather industry. Thus barriers are the major obstacle to adoption of sustainable supply
chain management practices in the leather processing factory.
In the category of technology, the barriers are the lack of technical expertise,
resistance to change and adopt innovation, lack of cleaner technology, outdated machinery
(Vachon and Klassen, 2007; Klassen and Whybark, 1999). All of those barriers hinder the
total sustainability of supply chain. In the context of leather processing factory, lack of
cleaner technology is one of the most important issues for adopting SSCM practices.
Therefore, the manager should give attention during the implementing stage. But the top
management of the industries of leather in Bangladesh has less interest in taking cleaner
technology as thinking the non-profit issue.
Another most common major category is knowledge & support. Under knowledge
and support, there are number of most common barriers present here that are information
gap, lack of commitment from top management, lack of training and education about
sustainability, limited access to market information (Guler et al., 2000; Muduli et al.,
2013). The lack of awareness and lack of knowledge of benefits of sustainability is a prime
and major barrier to the implementation of SSCM practices in leather processing factory.
The category of society also indicates the significant barriers to SSCM
implementation. Society pressure can be key success factor for an industry to the adoption
of SSCM practices in leather processing factory of Bangladesh. Hence, absent of society
pressure is a major barrier. There are four most common barriers are present here that are
the lack of government support & guideline to adopt sustainable supply chain practices,
the absence of society pressure, lack demand & pressure for the lower price, less of
business-friendly policy (Prakash and Barua, 2015). In Bangladesh, the companies also
don‘t show any interest as Govt. policy doesn‘t comply with directly or doesn‘t encourage
in green practices. Lack of support from the government towards the sustainable supply
chain management practice is a significant barrier.
The last and final major barrier category is the financial burden. In this category,
there are some most common barriers are present. Financial issues are the top priority
13
considerations in the implementation of SSCM practices in Bangladesh. The cost of
sustainability & economic condition, capacity constraints, lack of funds for sustainable
supply chain practices, green power shortage are the major barriers in this category
(Kulatunga et al., 2013; Presley et al., 2007). All of those barriers are the major issues
during SSCM implementing practices. Due to the lack of infrastructural facility, most of
the industries do not show the interest to take SSCM practices. Co-operative support from
all members of the supply chain is desired during the proper implementation of reverse
sustainable supply chain infrastructure in leather industries of Bangladesh.

Methodology
3.1 Research Methodology
The aim of this thesis is to find out the most influential barriers to adoption of
SSCM practices in leather processing factory using grey based DEMATEL methodology.
To apply the research framework in a real life problem, we need to finalize the most
common SSCM implementing barriers. Based on the survey of literature on SSCM
implementing barriers, and discussion with the team of four members in which three
members are from case company and one from academic experts. In this thesis, 35 barriers
are identified from existing literature review and from field survey on leather processing
factory. From 35 existing SSCM implementing barriers, twenty barriers are taken into
account for analyzing and evaluation of most influential barriers.
The proposed research framework is shown in Fig. 3.1 which is used for this
study to find out the most influential barriers to adoption of sustainable supply chain
management practices in leather processing factory of Bangladesh.

3.2 Solution Methodology
Grey theory, DEMATEL method, application of grey-DEMATEL approach and
procedure of grey-DEMATEL approach are presented in this section subsequently.
3.2.1 Grey Theory
Grey theory from grey set was first initiated by Deng in 1982 (Deng, 1982). Grey
systems methodology can manage many of the uncertainty decision which is created from
human decisions (Julong, 1989; Liu and Lin, 2011; Fu et al., 2001). Grey system theory
has successful applications in different fields such as manufacturing industries, agriculture,
economics, earthquakes, medicine etc. Any of the decision-making process can be
successfully done by grey system analysis, so as to improve the rightness of judgments (Li
et al., 2007). The grey number can be described as the number of uncertain data which can
generate required outcome with the small amount of data (Dong and Luo, 2006). Grey
numbers are easily convertible into crisp numbers using modified- CFCS (converting
fuzzy values into crisp scores) method by three step procedure (Fu et al., 2012). Grey
theory was introduced from a grey set by combining the concept of system theory, space
theory and control theory (Liu et al., 2011). The most import thing is grey theory can be
combined with any decision making methods to improve the quality of judgments (Arce et
al., 2015; Asad et al., 2016). One of the main advantages of grey system is that it can give
acceptable outcomes by using small amount of data. Therefore, grey theory is used to
solve various uncertainty problems with discrete data. As grey theory is very suitable to
combine itself to any multi-criteria decision-making method, we will use DEMATEL with
grey theory that means we will use grey DEMATEL method to get our desired result more
perfectly (Su et al., 2015).
3.2.2 DEMATEL Method
Decision-making trial and evaluation laboratory (DEMATEL) method is best
suited for analyzing a complex casual relationship among various factor or barriers (Hsu et
al., 2013; Wang et al., 2012; Jeng and Tzeng, 2012). DEMATEL is a structural modeling
17
approach which can show the interdependence among various factor and show the
influential cause-effect relationship in the form of a digraph (Büyüközkan and Ifi, 2012;
Chen and Chen, 2010; Shen et al., 2011). In DEMATEL method, all the factors or barriers
are divided into cause and effect group so that it helps to find the casual relationship
among multiple barriers. Basically, DEMATEL is a digraph theory which helps to realize
the cause and effect of the system by dividing into zone. Grey-DEMATEL approach can
be successfully applied to analyze the relationship between multiple factors (Shao et al.,
2016). In this study, grey theory has been combined with famous DEMATEL method to
get the more perfect result. Combining grey theory with other MCDM method, results in
more perfection in the result. DEMATEL is a powerful technique in the casual analysis
that helps researchers to divide the involving criteria into cause and effect group (Su et al.,
2015). This method can convert the relationship between cause and effect into a structural
system and also can reduce the number of criteria for evaluation. DEMATEL itself is a
very powerful technique and combining it with grey theory definitely gives it more
calculative power to solve the problem (Wu et al., 2011). It can be applied to the
managerial problem.
3.2.3 Application of Grey-DEMATEL Approach
The application of grey-DEMATEL appears in several fields including electronic
industry (Rajesh and Ravi, 2015), food packaging industry (Zhigang Wang et al., 2015a),
hospital service (Shieh et al., 2010), auto spare parts industry (Wu and Tsai, 2011). In
order to obtain the advantages of both grey theory and DEMATEL, we have chosen of
these two methodologies in this thesis to evaluate and analyze causal relationships among
common barriers of sustainable supply chain management practices in the leather industry
of Bangladesh.

3.2.4 Procedure of Grey-DEMATEL Methodology
Step 1: Compute the initial relation matrices
Let the number of identified common barriers to sustainable supply chain
management practices be ‗n’ and the respondents chosen to be l. Each respondent k is given
the task of evaluating the direct influence of barrier i over barrier j on an integer scale
ranging from 0, 1, 2, 3, 4, 5, indicating “no influence”, “very low influence”, “low
influence”, medium influence”, “high influence” and “very high influence” subsequently
among n barrier. Thus, set up l initial comparison relation matrices based on ratings obtain
from respondents.
Step 2: Compute the grey relation matrices
An upper value and lower value of grey scales need to be identified from the integer
rating scale (Deng, 1982; Deng, 1989). i.e.,
, . (3.1)k k ky y yij ij ij
Where, 1 ;1 ;1 .k l i n j n
The initial relation matrices are converted into grey relation matrices based on the
obtained grey values,
i. e. 1 2 3, , ,......., .ly y y yij ij ij ij
Step 3: Calculate the average grey relation matrix
The average grey relation matrix [⊗ yij ] is computed (Lin et al., 2004; Kose et
al., 2013) from l grey relation matrices, ;kyij
k= 1 – l as,
, . (3.2)
k ky yij ijk kyij l l
19
Step 4: Calculate the crisp relation matrix from the average grey relation matrix
The grey values are modified into crisp values by modified- CFCS method (Arikan
et al. 2013; Dou et al., 2014), following a three-step procedure which is described as
follows;
(i) Normalization of the grey value
. min max/ (3.3)miny y yjij ij ij
Where .
ijy indicates the normalized lower limit value of the grey number ijy .
. min max/ (3.4)miny y yjij ij ij
Where .
ijy indicates the normalized upper limit value of the grey number ijy .
max minmax . (3.5)min y yj ij j ij
(ii) Calculating total normalized crisp value
. . . .

(iii) Computing the final crisp values
min max* , (3.7)miny ZZ ijj ij
And *ijZ Z . (3.8)
Step 5: Calculate the normalized direct crisp relation matrix
In this step, the normalized direct crisp relation matrix, P is obtained by computing
Q and multiplying Q with the average relation matrix Z. i. e.,
20

1 ,max *1 j

Z iji n
(3.9)
And, P=Z×Q. (3.10)
Each element in matrix P falls between zero and one.
Step 6: Compute the total relation matrix
In this step, the total relation matrix, T is calculated by the following equation,
1 (3.11)T P I P
Where, I is the identity matrix.
Step 7: Obtain the cause and effect parameters by summing rows and columns
Assume ijt denotes the elements in the total relation matrix, T. Let r and c be
defined as n×1 and 1×n vectors representing the sum of row elements and sum of column
elements for the total relation matrix T, respectively. If ri represents the sum of ith row
elements in matrix T, then ri summarizes both direct and indirect effects given by barrier i
towards the other barrier. If cj represents the sum of jth column elements in matrix T, then
cj summarizes both direct and indirect effects received by barrier j from other barriers, i.e.,
1nr t iji ij
(3.12)
1nc t jij ij
(3.13)
When j=i, the sum i jr c indicates the total effects given and received by barrier
i; i. e, i jr c represents the degree of importance that the barrier i plays in the entire
system. On the other hand i jr c outlines the net effect that the barrier i
contributes to the entire system. If i jr c is positive, barrier i is the net cause.
Barrier i indicates the net effect if i jr c comes out to be negative value.
21
Step 8: Compute threshold value from total relation matrix and plot the digraph
Total relation matrix, T provides information on how one barrier affects another
barriers, a threshold value needs to calculate to avoid the complexity to plot the diagraph.
Calculated threshold value indicates that the greater value than threshold has higher
influence during SSCM implementing. Threshold value is usually computed by sum of the
mean value and standard deviation of elements in the total relation matrix T. In digraph,
causal relations is plotted from the dataset of , .i j i jr c r c i j

A Case Study
4.1 Application of the proposed research framework
This proposed research framework is applied in a leather processing factory in
Bangladesh. The case leather processing factory has shown as a representative case
selected for implementation of sustainable supply chain management practices. XYZ is a
global export oriented leather processing factory of Bangladesh which exports leather to
different developed countries like Germany, Italy, and China and also meets demand for
Footwear Company of their own brand. Supply chain network of XYZ is indirectly
globally distributed their products and it is important to consider sustainable supply chain
management practices in their traditional supply chain. To introduce the sustainable supply
chain management practices in their leather processing factory is a top most recent
concern.
Recently this leather processing factory is interested in implementing sustainable
supply chain management practices. They want to find out barriers to adoption of
sustainable supply chain management in their TSCM. This study helps to find out the most
common barriers to adoption of sustainable supply chain practices in leather processing
factory supply chain. In this study, 20 common barriers ware collected from the literature
reviews with the help of industry experts and academic expert.
23
4.2 Data Collection
In the process of data collection, a team of four experts, three from the relevant
industry and one from academic expert, is constructed. Table 4.1 shows the team members'
profile. To improve the validity and reliability of thesis, triangular approach (Azevedo et
al., 2013) could be applied in this thesis. Triangulation approaches are of three types-data
triangulation (combining multiple data sources), methodological triangulation (using
multiple research methods to analyze the same problem, or investigator triangulation
(using multiple investigators to work on the same task. In this thesis, data and investigator
triangulation approach are utilized. The required data are collected from industry
professionals and academic expert. Here, data collection is performed in two phases, which
are illustrated below.
Phase-1: Finalizing the most common barriers for implementing sustainable
manufacturing practices
At first, identify 35 barriers to adopting sustainable manufacturing practices in
different industries through a survey of literature and investigate the relevant sector. These
barriers may be applicable to specific industry category for a specific country. To identify
suitable barriers in the social, economic, and technological context of Bangladesh, the
experts are asked to add or delete any barriers to undertaking sustainable manufacturing
practices in the leather industry. In this study, collect responses from the experts and then
arrange several discussion sessions to finalize the barriers. Thus, 20 barriers are identified
for this study. We proceed to the next step of this thesis by taking input from experts to
evaluate comparison among identified barriers for the purpose of developing a grey-
DEMATEL model. For the sake of confidentiality, the name of the companies is not
mentioned here.
Phase-2: Evaluation of comparison among identified barriers to sustainable manufacturing
practices
We communicate the objectives as well as the brief methodology of this thesis to
the expert panel and we ask them to fill a pair-wise comparison matrix necessary for
developing a grey-DEMATEL model. The barriers to adopt of sustainable supply chain
24
management practices have been considered in the study and their relevant literature is
given in Table 4.2 which is shown in Appendix A.
A summary of codes used for the most common barriers to adoption of SSCM practices for
the ease of reference is shown in Table 4.3.

The applications of proposed framework to the case of leather processing factory XYZ is
explained as follows:
Step 1: A group composing of 3 supply chain experts and 1 academic expert is formed to
evaluate the direct influential barriers among twenty common barriers to adoption of
SSCM practices for the case leather processing factory XYZ. The supply chain experts and
academic expert selected based on 10 years of working experience in the relevant field.
They evaluated the direct influence of one barrier to the other barriers on linguistic
provided grey scales varying from “no influence‖ to “very high influence‖. Four initial
comparison matrices (20×20) are formulated based on the integer grey scale ratings.
Linguistics ratings of grey scales are given in Table 4.4 for formulating comparison
relation matrices.

Step 7: Let r and c defined to be 20×1 and 1×20 vectors representing sum of row
values and sum of column values for the total relation matrix T, respectively. Using
Equations (3.12) and (3.13) ir and jc values are computed. ir denotes sum of row i
and the values of ir indicates direct and indirect effect of barrier i over other
barriers for sustainable supply chain management practices. jc represents sum of
column j and the values of jc indicates overall direct and indirect effects of barriers j
to all other barriers. The cause and effect parameters i jr c and i jr c is
constructed from the total relation matrix, T for values i=j, which is presented in Table
4.13.

Step 8: Develop cause and effect digraph by using total relation matrix. A
threshold value (θ=0.178) is calculated by adding the standard deviation (σ) to the mean
(µ) of the elements in the total relation matrix T, to find out comparably negligible cause-
effects among different barriers. Fig. 4.1 indicates the obtained digraph showing cause-
effect relationship among the common barriers, plotted from the dataset of
(( ) ( )) , i j i jr c r c i j . The arrow represents the direction from cause barriers to effect
barriers to adoption of sustainable supply chain management practices. Two-way
significant relationships among barriers are represented in dotted lines whereas one-way
relationships among barriers indicated by solid lines in Fig. 4.1.

Chapter 5
Results and Discussions
In this section, the final results are presented. Table 5.1 reveals the cause-effect
relationship among various SSCM implementation barriers in leather processing factory of
Bangladesh. A grey based DEMATEL approach is applied in this thesis to evaluate and
analyze most influential barriers to adoption of sustainable supply chain management
practices in case of the leather processing factory supply chain. A threshold value of
0.178 is considered in this thesis to reduce the complexity of digraph and to eliminate
some of the minor effect of barriers. Threshold value is computed from total relation
matrix T. The barriers are ranked on its importance the based on i jr c i j values as
follows; KS1>KS2>S1>F1>S2>T3>KS4>E4>T4>E1>F2>T1>E3>E2>T2>F3>S3>KS3>

follows, E4>KS2>F1>E1>S1>S2>KS4>KS1>T3. In this casual group, Lack of awareness
of local customer in green products (E4) and Lack of commitment from top management
(KS2) seem to be the crucial driving barriers, as those can effect of many other barriers to
SCCM implementation in leather processing company. We discuss the result with industry
experts and academic experts and they accepted those barriers as major barriers to
adoption of SSCM implementation. Lack of awareness of local customer and lack of
interest of top management are the major two hindrances of SSCM implementation. Lack
40
of awareness of local customer (E4) is on the category of environmental issues which
could obstacle the green supply chain implementation. When the customers are the lack of
awareness about green products the ultimate result is top management would not interest to
implement SSCM in their TSCM network.
Lack of commitment from top management (KS2) seems to be the major casual
issues during the SSCM implementation in respect to Bangladeshi leather processing
industry. In Bangladesh, top management is not interested to implementation of SSCM
because of sufficient funds not available and this implementation needs large investment.
Hence, this barrier is big issue during SSCM implementation. SSCM practices into TSSC
system needs large investment to modify the existing system and hence, top management
does not want to implement SSCM in their company especially in leather processing
industry. In leather processing industry, the top management is not aware about green
supply chain as well as SSCM.
The third position for barriers of SSCM implementation on importance goes to
cost of sustainability and economic condition (F1). This barrier takes place in casual
group. Therefore, cost of sustainability and poor economic condition is responsible to
hinder the implantation of SSCM in traditional system. In Bangladesh, SSCM
implementation is not an easy practice because of its cost to implement and need for
economic stability.
Lack of eco-literacy amongst supply chain partner (E1) is the forth casual barrier
that means in Bangladesh, the supply chain partners are not conscious about eco-products.
The lack of environmental knowledge is responsible to implement SSCM. The next casual
barrier is lack of support and guideline from regulatory authority (S1) and is one of the
most influential barriers that can directly influence other barriers during SSCM
implementation in leather processing industry. In Bangladesh, the regulatory authority do
not give support for SSCM practices and also not have any regulation for practicing SSCM
into manufacturing industry. This barrier is one of the major obstacles. Hence, it is
necessary to eradicate this barrier to influence other barriers during SSCM practices.
41
Absence of society pressure (S2) is an additional important casual issue during
SSCM practices. Bangladesh is an over populated country. The people are not conscious
about green products, sustainability, environmental issues. This turns to bad impact in
manufacturing industry. It‘s a great opportunity to drive other barriers by introducing
consciousness in society about green products and harmful effect of environment.
Lack of training and education about sustainability (KS4) is knowledge and
support related casual barrier. Introducing training and education can help to adopting
sustainable supply chain management practices in leather processing industry because in
leather processing industry not only employer but also owners of industry not have
sufficient knowledge about sustainability. By introducing training can help to modify
TSCM to SSCM in their supply chain network.
Information gap (KS1) is the eighth ranked casual barrier. An overall gap of
information on sustainability, green supply chain, reverse logistics, social sustainability,
and economic sustainability is one of the major barriers for adopting sustainable supply
chain management practices. Overcoming this barrier can help to implement SSCM
practices in leather processing industry.
The last one identified is the lack of cleaner technology (T3). Lack of cleaner
technology is largely responsible for destroying environment especially for leather
processing industry because of waste water directly imposed to river and polluting the air,
soil, and water. In Bangladesh, leather industry is directly responsible for environmental
degradation. The chemical use in tannery industry directly produces solid waste which can
pollute water as well as soil directly. Introducing cleaner technology for SSCM can largely
help to modify the current situation.
5.2 Effect Group
The effect group can be sorted on the basis of i jr c i j in Fig. 4.1 as
follows; T2>S3>S4>F4>E2>F3>KS3>F2>T1>T4>E3. The eleven barriers are directly
influenced by casual nine barriers which are hindrance to adopting SSCM practices in
42
leather processing factory in Bangladesh. Resistance to change and adopt innovation (T2)
is near to casual group and hence, has less influence by casual barriers. Resistance to
change and adopt innovation is the barriers of SSCM implantation which could influence
by other casual group and it is necessary to eradicate during introducing SSCM practices.
Other effect barriers are lack of demand and pressure for lower price (S3), less business-
friendly policy (S4), green power shortage (F4), lack of environmental requirement (E2),
lack of funds for sustainable supply chain practices (F3), limited access to market
information (KS3), capacity constraints (F2), lack of technical expertise (T1), outdated
machinery (T4), lack of practices on reverse logistics (E3). All of those barriers can easily
influence by casual barriers. During implantation of SSCM practices, it‘s necessary to
identify the cause and effect group to take action against barriers. This thesis could help to
the manager to identify this cause-effect relationship for introducing SSCM practices in
leather processing factory.
5.3 Correlation among the Barriers
The center of barriers can be ranked as follows on the basis of i jr c i j and
it is shown by following ways, KS1>KS2>S1>F1>S2>T3>KS4>E4>T4>E1>F2>T1>E3
E2>T2>F3>S3>KS3>F4>S4. Information gap (KS1) seems to be the highest correlation
with other barriers because overall information about sustainable supply chain can force
other barriers to adopt SSCM practices in existing supply chain and for the new
entrepreneur. In Bangladesh, the major obstacle is information gap. Insufficient knowledge
on the sustainable supply chain is the major issue for SSCM implementation. In
Bangladesh, every branch of supply chain network everybody is not conscious about green
products, reverse logistics, social issues, environmental requirement, and knowledge about
sustainability. Thus the ultimate result is pollution of water, soil, air etc. Bangladesh needs
to undertake the various training and educational facility of SSCM that ensure the
manufacturer, customer to conscious about environmentally friendly products.
43
In this study, one barrier is directly influenced by another barrier. In Fig. 5.1, the
barriers located above the x-axis have the most influence on the network and are indicated
as casual group barriers. The other barriers which are located under this line are indicated
as influenced group. The barriers are shown in Fig. 5.1 can be divided into four regions for
accurate analysis of their influences. In Fig. 5.1, zone 1 represents the barriers with the
least influential effect to other barriers and their importance is low. Resistance to change
and adopt innovation (T2), lack demand and pressure for lower price (S3), less of
business-friendly policy (S4), green power shortage (F4), lack of environmental
requirement (E2), lack of funds for sustainable supply chain practices (F3), limited access
to market information (KS3), lack of technical expertise (T1) and lack of practice on
reverse logistics (E3) barriers are under this zone. Zone two represents the casual relation
among different barriers which has less influence in SSCM implementation. In this zone,
there is no barrier.
Therefore, zone three represents the barriers which have the highest significance.
These barriers are located in the casual group and should consider for SSCM
implementation. These barriers are indicated as strong success factor to adopting SSCM
practices in leather processing supply chain. Therefore, these barriers help to the manager
to undertake proactive and reactive step to adopting SSCM practices in their supply chain
network. Lack of awareness of local customers in green products (E4), lack of
commitment from top management (KS2), cost of sustainability and economic condition
(F1), lack of eco-literacy amongst supply chain partner (E1), lack of support and guideline
from regulatory authority (S1), absence of society pressure (S2), lack of training and
education about sustainability (KS4), information gap (KS1), lack of cleaner technology
(T3) barriers come under this zone.
Zone four indicates the barriers which have high significance but is suited in the
under the x-axis that means it is suited in effect group. In these zone barriers capacity
constraints (F2) and outdated machinery (T4) take place into account which have high
influenced during SSCM practices by other casual barriers.

5.4 Sensitivity Analysis
Sensitivity analysis is a process to test the robustness of the gained results. For the
purpose of testing robustness of obtained result different weighting has been assigned for
one expert while keeping equal weightings for the others experts. This can be done in a
number of ways, as for example, by changing the level of weightings given to an expert or
by changing the level of weightings to various barriers. In this study, we use archetypal
sensitivity analysis by assigning separate weightings to experts and academic. As for
example, first, the weight assigned for experts-1 is 0.4 while keeping the same weight for
other that is 0.2.
For sensitivity analysis, at first we made four separate total relationship matrix by
multiplying each assign weight in respond to Table 4.2, 4.3, 4.4 and 4.5. After that,
average relationship matrices have been computed and finally cause-effect relationships
among different barriers have been established. The weight assigned for different
evaluator, cause-effect relationships of different barriers and ranking of different barriers
during sensitivity analysis are shown in Table 5.2, 5.3 and 5.4.

From the above plotted diagraph it is clear that there is no major change in
ranking among various barriers during sensitivity analysis. This results show the same
priority ranking order for cause-effect barriers for each experts and academic, accepting
minor order variation. Hence, there is no serious change in ranking during sensitivity
analysis. Therefore, sensitivity analysis ensures the robustness of obtained results.
5.5 Managerial Implications
The results of this study reveal important implications for decision makers during
sustainable supply chain management implementation. From the study results, several
managerial suggestions are formed. Therefore it is important to focus on the cause group
barriers due to their direct influence on the effect group barriers. It is evident from
obtained results that identification of most influential barriers in industries during SSCM
adoption is necessary to ensure sustainable manufacturing practices as well as for
sustainable development (Luthra et al., 2011; Muduli et al., 2013; Rauer and Kaufmann,
2015). Hence, this study helps decision maker to identify the most influential barriers to
give more attention during SSCM implementation. Managers are able to define which
barriers within their industries need greater attention and which barriers may be given less
importance. The ranking of cause group and effect group barriers assist manager to take
action during SSCM implementation. During the sustainable supply chain management
implementation, this thesis framework will be effective for analyzing and identification of
numerous barriers. This proposed framework will be helpful for the industrial manager to
systematically organize their decision by proper planning and by computing the relative
importance and influence of different SSCM implementation barriers by using grey-
DEMATEL approach and on the industries SSCM program.
This thesis gives direction to a better understanding of the cause-effect
relationship of SSCM barriers. The effect group can easily influence by the cause group
and therefore managers need to attention on cause group during implementing SSCM
practices in their traditional supply chain. The results of this thesis could encourage
managers and top management to the adoption of SSCM practices which are more
54
important for sustainable development of a country and have a great effect on the
traditional supply chain. The sensitivity analysis results help to evaluate the stability of
experts and academic practitioner‘s opinion. The manager can consider this framework for
a benchmarking to improve the traditional supply chain which leads to improving
environmental, social and economic sustainability (Chin et al., 2015). The results reveal
that lack of awareness of local customers in green products (E4), lack of commitment from
top management (KS2) and cost of sustainability and economic condition (F1) takes place
first three priority casual barriers. Therefore, decision maker and manager should take
attention to those casual barriers during SSCM implementation. It is necessary to provide
governmental support and regulation to motivate companies for SSCM practices.
Therefore managers should understand that results of this thesis could be changed due to
the case situation.

Conclusions and Recommendations
6.1 Conclusions
Foreign buyer pressure, global market demand and environmental policies, the
organizations are pushing to implement sustainable supply chain management practices in
their traditional supply chain network for sustainable development (Mathiyazhagan et al.
2014). For this reason, environmental sustainability, green issues, social sustainability
have an increasing popularity among researchers and supply chain practicing managers
(Hutchins and Sutherland, 2008; Zhu et al., 2008; Giannakis and Papadopoulos, 2016; Xia
and Tang, 2011). Implementing SSCM practices in industries can ensure the long-term
environmental, social and economic benefits for both organizations and customers. Hence,
it is not easy task to implement SSCM in traditional supply chain network because of there
are numerous barriers present (Chkanikova and Mont, 2015; McCormick and Kåberger,
2007; A Sajjad et al., 2015). The goal of this thesis work was to identify and analyze
barriers that play a crucial role in hindering the implementation of sustainable supply chain
management practices in leather processing factory. Literature reveals that no study found
on sustainable supply chain management implementation in leather processing factory of
Bangladesh by using grey DEMATEL approach. This study has attempted to present
framework to analyze the barriers to adoption of SSCM practices in leather processing
factory with the help of a blended grey DEMATEL approach. The major contribution is to
identify and analyze the barriers from existing literature review and investigation of
relevant leather processing industry. 35 initial barriers are taken from existing literature
review and discussion with industrial experts. Twenty barriers are identified from 35
barriers through the initial survey. Therefore, it is not easy to eradicate all these barriers to
56
adoption of SSCM practices so industries must need to identify which barrier is major
obstacle for SSCM implementation. After discussion with experts and academic personnel,
a blended grey DEMATEL methodology is used which helps to identify cause-effect
relationships among different barriers, effectively ignoring imprecise judgments. In this
thesis, lack of awareness of local customers in green products and lack of commitment
from top management seem to be the most important barriers during SSSCM introducing
in traditional supply chain. Outdated machineries and lack of practices on reverse logistics
seem to be the most influential barriers that means other barriers can easily influenced to
those barriers and improvement of other barriers will directly influence those barriers.
Therefore our motivation is that this study helps to managers and planner to identify most
influential SSCM implementing barriers and eradicating those barriers by taking necessary
steps. Other industrial sector like textile, polymer, electronics, footwear, leather goods, and
mining of Bangladesh can also get idea from this thesis to find out the barriers for
sustainable manufacturing practices.
6.2 Recommendations
In this thesis, grey based multiple criteria decision-making tool DEMATEL is
proposed for analyzing and identifying of SSCM implementation barriers and a real life
industrial case study is introduced to show the way of testing proposed research model in
Bangladeshi context. The expectation is that this thesis will help to other industrial fields
of Bangladesh to evaluate barriers during SSCM implementations. This thesis could be
used for other industrial sector of Bangladesh like garments, footwear, leather goods,
polymer, food processing, mining, chemical, pharmaceutical etc. All of those industrial
sectors have harmful effect on environments and society. This thesis helps to industrial
manager to convert traditional supply chain to sustainable supply chain by considering
priority ranking of casual group barriers. This thesis cannot take all the barriers for
analysis. For this reason, other industrial sector can take relevant barriers for their analysis.
In future, other multi criteria decision making tools like Fuzzy-AHP, Fuzzy-VIKOR,
Fuzzy-DEMATEL, ANP, ISM, ELECTRE III, TOPSIS can be used for analysis barriers to
evaluate most influential barriers to adoption of SSCM practices (Bhatia and Chand, 2014;
Bhattacharya et al., 2014; Büyüközkan and Çifçi, 2012; Mangla et al., 2015; Wang et al.,
2012; Govindan et al., 2015; Sawadogo and Anciaux, 2009).
