Abstract :
The process of evaluating and selecting suppliers should be done by examining all possible options and scenarios for each contractor, otherwise the organization will face a lot of difficulties in the implementation and implementation phase of the commitments. The purpose of this study was to determine the indifference points of the suppliers of gas companies in Zanjan province.This study is descriptive. The data of this study is related to the evaluation of suppliers of Zanjan province gas company projects. The data was collected based on the views of 10 experts with at least a bachelor's degree and at least 5 years of work experience in the company based on the "supplier assessment form". The data has been analyzed using the 2014 version of MATLAB software.A total of 6 items of matrix matched with the initial decision matrix are identified and generated for each method.TOPSIS-GA = 2 and TOPSIS-PSO = 3 and AHP-GA = 2 and AHP-PSO = 3. From the results of the ranking of options, the third-party contractor has ranked first among the other options. Depending on the indeterminate matrices identified, different scenarios are set for the third contractor. Considering the company's budget and expectations that are more in line with the fourth indifference point (OUT PUT-5-AHP-PSO), the third contractor is being asked to strengthen his capabilities so that he will succeed in the contract with his chance for future cooperation. Increase.
