A fuzzy goal programming approach for vendor selection problem in a supply chain

A fuzzy goal programming approach is applied in this paper for solving the vendor selection problem withmultiple objectives, in which some of the parameters are fuzzy in nature. A vendor selection problem has beenformulated as a fuzzy mixed integer goal programming vendor selection problem that includes three primarygoals: minimizing the net cost, minimizing the net rejections, and minimizing the net late deliveries subject torealistic constraints regarding buyer's demand, vendors' capacity, vendors' quota flexibility, purchase value ofitems, budget allocation to individual vendor, etc. An illustration with a data set from a realistic situation isincluded to demonstrate the effectiveness of the proposed model. The proposed approach has the capability tohandle realistic situations in a fuzzy environment and provides a better decision tool for the vendor selectiondecision in a supply chain
