Sensitivity analysis Decision techniques and weighting techniques in multiple attribute decision making Case Study (priority public transport systems in Qom)

Abstract

Abstract . In recent years, academic societies have to pay more attention to the decision-making techniques and much academic research in this field has been done, but in choosing the appropriate decision, especially in the case of multi-criteria decision-making, Studies are not enough. This paper examines real case shows that the type of technique used, in both weight and in the decision-making Undeniable impact on the rankings achieved, It also specifies how to rank the resulting decisions using various methods to compare and evaluate them. This article describes three methods of multi-criteria decision-making methods of the decision of the three subsidiaries(SAW method of subset grading and Rating, TOPSIS method of subset compromise and ELECTRE method of subset Coordination) and Three methods of weighting factors(Entropy technique, AHP Technique and the combination of entropy and AHP techniques) Is evaluated. The assessment in the case of the city of Qom, in order to prioritize public and suburban transport system of the city is studied . According to the survey, the results of entropy techniques among different methods of weighting, is not a very stable And the results of the decision-making techniques, SAW, high relative stability compared to other techniques, this means that the results of this technique is low sensitivity to the weighting.
