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.

Keywords: green supplier selection; analytic hierarchy process; multi decision-making; fuzzy TOPSIS.
