| Abstract
Nowadays integrated multi-criteria decision making (MCDM) and geographic information system (GIS) is commonly used in order to solve spatial problems. Different multi-criteria decision making techniques present different methodology with certain limitations and advantages. Regarding to those mentioned limitations it is not simple to choose one of them. In this article, combinational FAHP technique is used in order to minimize the mentioned limitation, by using Fuzzy and AHP technique we propose a methodology for site selection problem. After importing green space criteria in GIS frame work we use them as criteria in AHP tree. In this methodology by utilizing improved Analytical Hierarchy Process by Fuzzy set theory, we try to calculate weight of each criterion. FAHP is AHP improved by fuzzy set theory which is a useful approach for evaluating complex multiple criteria alternatives involving subjective and uncertain judgment. By using fuzzy set theory in AHP method the qualitative judgment can be qualified to make comparison more intuitionists and reduce or eliminate assessment bias in pair wise comparison process. |
