Abstract :
The location of industrial area is a key factor in regional planning because this kind of decision haslarge social, economical and environmental impacts on any land. Location decision makers mustconsider a wide range of factors in order to coordinate socio-economic benefits and environmentalsustainability. Isfahan is one of the most important industrial centers in Iran and because of largeindustrial development in this region industrial construction is limited to 50 Km radius around Isfahancity. The present paper describes a Multi-Criteria Decision Analysis (MCDA) method, calledWeighted Linear Combination in GIS environment to evaluate the suitability of 50 Km radius aroundIsfahan for industrial establishment. At first by literature review and obtaining standards, industrialsite selection criteria are defined. The relative importance weights of criteria estimated usingAnalytical Hierarchy Process (AHP) and pair-wise comparisons. Finally all criteria layers areaggregated by WLC. After the elimination of sites which do not have enough area for industries, 4suitable patches for industrial construction are found
