Institute of Production Systems and Logistics (IFA)

The Institute of

Production Systems and

Logistics is located in

Garbsen.

The IFA is one of 17

institutes of the

engineering faculty of the

Leibniz University in

Hanover.

The IFA is the biggest

Research Institute in the

field of Production

Logistics in Germany.


Principles of PZH

• Concentration of production engineering by combining

7 institutes

• Support of communication by sophisticated architecture

• Integration of science and industry

Excerpt from the Causality Diagram


Clustering of Sustainability Enablers

First step:

• Analysis of characteristics,

regarding to corresponding

criteria

• Development of the

similarity matrix and

coefficient

Second step:

Using of a fusion algorithm

Corresponding criteria

ristics

Binary affiliation

0 = not corresponding

1 = corresponding

Used corresponding

criteria:

• Elements

• Stakeholder

1. Using of a fusion algorithm

2. Development of cluster groups

Calculation of similarity coefficients

(e.g. using of RR-coefficient)

S = similarity

a = available at 1 and 2

b = available only at 1

c = available only at 2

d = not availabledcba

Third step:

Development of sustainability enablers

Maturity Model

1 Definition of an evaluation scale:

Using of sustainability characteristics . The amount of fullfilled

characteristics determines the target maturity level.
