An Approximation to Multisource Supplier Selection Problem using Extended Fuzzy AHP and GA

Nowadays, within new important strategies for production price and quality, supplier plays a key role in the corporate competition. Because of this reason, supplier selection must be considerate for all corporate. Supplier selection may include a multi criteria problem which includes both qualitative and quantitative factors for example purchase cost, quality level, supplier risk etc... Selecting best supplier is necessary to make a trade off between tangible and intangible factors. In this work we suggested to integrate Analytic Hierarchy Process (AHP), Fuzzy AHP and Genetic Algorithm (GA) to determine best suppliers. Fuzzy set will be utilized linguistic factor to organize criteria and sub criteria weight,with pairwise compare with fuzzy AHP; it will be utilized to organize all factors and which assigned weighting for related factor. Finally, a hypothetical supplier selection problem will be solved by proposed (GA) algorithm.
