Presenting a Model for Evaluating and Ranking Fuel Stations Based on AHP Approach

In this article، an evaluating model for ranking the fuel stations of N. I. O. P. D. C. is presented. The model was formulated based on one of MCDM techniques known as Analytical Hierarchy Process (AHP). More specifically، initially، we conducted a survey through administering a questionnaire to experts in order to identify the criteria for evaluating fuel stations. Then، we determined criteria weights using a questionnaire on the basis of AHP standard. We used a rating scale instead of direct pair wise comparisons among alternatives so that we could overcome the explosion in the number of required comparisons when the number of alternatives is excessively large. Then، we calculated global Weights of every criterion in each level and after that considering assigned rates by evaluators to every fuel station، the scores of every fuel station was eventually calculated. All of weights were calculated and run using EC software. To test the presented model، we evaluated four stations in Zanjan province.
