Facility Location - Allocation using

ArcGIS:

A case study of Amaravati City,

Andhra Pradesh

Dr. Rajiv Gupta Senior Professor

Lalu Saheb K M.E- Infrastructure Engineering & Management

BITS Pilani, Pilani Campus

• Quantification of given facilities by location-allocation analysis

and OD cost matrix analysis in ArcGIS.

• By using OD cost matrix analysis, calculated accessibility

index for each origin and destination points.

• As per the accessibility index values, replaced the locations of

facilities in prioritizing order taken from questionnaires.

Aim and scope:

BITS Pilani, Pilani Campus

Introduction:

• Andhra Pradesh is building a new Capital City named

Amaravati.

• The Andhra Pradesh State Government has assigned a 7,325

km2 area for Capital Region.

• Amaravati is to be built in 391 square kilometres in Guntur

district, on the bank of the Krishna River.

• It will be 12 km north-west of vijayawada city and 20 km north-

east of Guntur city. It would comprise 33 villages in three

mandalas.

• The master plan is given by Singapore and The Japanese

companies are ready to associate in construction.

This study integrates GIS and geospatial analytical methods

based on location allocation & OD cost matrix models with

the following objectives:

• To evaluate and assess the locations of facilities given in

approved master plan of new capital city.

• To find which part of the city might be seriously uncovered

and inaccessible from facilities within the standard

response distance.

• To find out if new facilities should be established in

strategic locations to under coverage or reallocation.

• Find optimal locations and reallocate facilities.

Origins – Residential high (127 locations)

Destinations – Medical centres (126 locations)

Network lines – 127x126 = 16002 lines.

• Here, I have exported the attribute table values I.e. origin

– destination distances for residential high to Medical

centres.

• In such a way that, exported 3 tables for below O-D’s:

• - Residential medium to medical centres

• - Residential low to medical centres

• - Residential mix to medical centres.

• Same procedure done for other facilities and exported

attribute tables in excel sheets.

• Finally got 32 maps & tables (4 Origins x 8 Destinations).

Definition : Accessibility refers to the ability to reach desired

goods, services, activities and destinations Or measure of

the relative access of an area or zone to population,

employment, opportunities, and community services.

Accessibility Index:

Individuals, based

at home

Desired activities

at destinations

Individual & activity

• Considered preferred distance value shown in table.

• Distance Ratio = Preferred distance/Existing distance.

• Accessibility Index = Distance Ratio/Max. distance ratio

value.

• Next insert pivot table. In this add origin and accessibility

index values.

• Then we can get final accessibility index values for each

origin point i.e. sum of each origin point to all destination

point distances.

• Same way find out for all other facilities.

• Take all the pivot tables in a single sheet and calculate

overall sum of all other facilities i.e. each origin point to

all the destination points of all the types of facilities.

• Continue the same for residential medium , residential

low & residential mix locations.

• We got the final accessibility index values for each

location.

• Calculated accessibility index values to all the destination

points followed the same procedure.

• But here considered average preferred distance by

weighted average method.

• Then take all the pivot tables in a single excel file. And

sort out in a single column in ascending order of

accessibility values.

• Next replace the facility locations as per the priority

ranking wise taken in questionnaire – l

BITS Pilani, Pilani Campus

• In this case, all residential locations (origin) taken in a

single shape file (append) and all facility (Destination)

location shape files merged in a separate append shape

file.

• Then loaded these shape files to the OD cost matrix origin

& destination classes.

• Continue the same procedure described above and

consider average preferred distance by weighted average

method.

• Here 452 habitants loaded into the origin class and facility

append file having 652 locations loaded into the facility

point class.

• In this research study, accessibility is the main object but

population density not considered.

• If we consider population densities along with

accessibility index value methodology, then we can get

better accurate results.

• As per these values, we can find the habitants which are

not serving by the particular facility or too far from facility

then subsequently increase the number of facility

locations or reallocate the facilities to bridge the gaps.

Recommendations:

BITS Pilani, Pilani Campus

• In this study, we are suggesting a better facility allocation.

• Considered quantification for all the facilities and habitants

at a time rather than considering single facility, because

facilities to be reallocated in a prioritizing order.

• Bus stops, WTP, water distribution plants, electrical power

plants locations not considered because special surveys

to be done for those locations9529318296.
