Designing a hybrid sourcing model in the supply chain by using ANP, VIKOR and multi-objective model in fuzzy environment of The Case: Alborz Cable Company

Supplier selection and quota allocation is an important decision in supply chains. This decision can be considered as a complex multi-criteria group decision making problem. This decision in many practical situations is very difficult for vague and uncertain environment. This vagueness and uncertaintycan be handled by using fuzzy set theory. Therefore, this paper proposed a fuzzy MCDM model to evaluate candidate suppliers and quota allocation. A hybrid ANP-VIKOR method in fuzzy environment applied first with 16 criteria to evaluate suppliers. Then, a fuzzy multi-objective mathematical model is used to quota allocation. Finally, the fuzzy model is solved by Tiwarimethod. An illustration with a data set from a realistic situation is presented to demonstrate the effectiveness of the proposed model.
