A hybrid fuzzy multi-criteria decision making model for green supplier selection

Abstract

Selecting appropriate suppliers has directly effect on this network efficiency, costs, quality and environmental performance. Hence, supplier selection is significant factor in supply chain success. Supplier selection is a multi-criteria problem, which involve uncertain qualitative and quantitative data. Thus, the aim of this paper is introducing an integrated model for green multiple sourcing in fuzzy environment. This proposed model considers various criteria and sub criteria to evaluate and rank best suppliers. First, fuzzy analytic hierarchy process has been used to find weight of each supplier. Then, a Fuzzy Technique of ranking Preferences by Similarity to the Ideal Solution (TOPSIS) method is developed to rank suppliers and select the appropriate ones. The proposed model helps managers to solve multiple-sourcing problem, reduce purchasing cost, lead time and improve quality and environmental issue.
