GIS based multiple criteria decision support system for urban planning problems in Gaziantep

Finding new service facility location is one of the main applications of industrialengineering. Service facility location problem has multiple criteria and multiplealternatives. Therefore, the solutions of such problems are difficult. GeographicInformation System (GIS) provides some easy ways to solve such difficult problems.In this thesis, a multiple criteria decision support system based on the GeographicInformation Systems is developed facility location type urban planning problems.The developed system is applied to three different urban planning location problemsin Gaziantep.Three different urban planning problems are investigated in this study: determinationof locations for hospitals in Gaziantep, determination of locations for supermarketsin Gaziantep, and determination of locations and the numbers of the police stationsin Gaziantep. In the first case, Analytic Hierarchy Process (AHP) is integrated withGIS to determine alternative places in which hospitals can be established and toselect the best place for the hospital. A computer program is developed for thatpurpose by using Visual Basic and MapBasic programming languages. In the secondapplication supermarket location problem is studied by using simple additiveweighting method (SAW) and GIS. In the third case, Set Covering Algorithm(SCA)is used with GIS for determination of locations and number of the police stations inGaziantep. The problem is solved by means of a computer program developed byVisual Basic.Keywords: Geographic Information Systems (GIS), Decision Support Systems,Multicriteria Decision Support System, Set Covering Algorithm, Buffer Analysis,Analytic Hierarchy Process (AHP), Simple Additive Weighting Method (SAW).ii
