Use of GIS-based Multi-Criteria Decision Making to Optimal Site Selection in an Illustrative Study Area in the Center of Iran

In order to obtain national and international high-speed transport system, optimization of choosing the airport place is very important in country development. Analytical Hierarchy Process (AHP) have possible in using the linguistic variables along quantitative variables and essentially is based on expert opinions. In recent years in order to increase the capability of AHP, this method combined with the fuzzy method and in the Fuzzy-AHP algorithm is presented. In this paper, analytic hierarchy process (AHP), one of multi-criteria decision making (MCDM) techniques in the fuzzy environment is applied to select the optimal alternative for airport site selection in a case study. Results show that using AHP in the fuzzy environment improves decision making through considering more important factors in decision making. So the goal of this research is to investigate the environmental factors incorporating with airport site selection and optimal design for airport site selection using the GIS-based methodology in an illustrative study area.
