A Vendor Selection Model For A Reverse Supply Chain Management

The aim of this paper is to determine the appropriate supplier providing the most customer satisfaction for the criteria identified in the Reverse supply chain Management. The choice of suppliers and their performance assessment are becoming major challenges that face supply chain managers or directors especially in Reverse Supply Chain Management. Evaluating suppliers and selecting one of them are complicated tasks due to the fact that various criteria or objectives must be considered in the decision making process. Also in many real world cases the criteria are not equally important for the purchase managers. In this study, we proposed a supplier selection analysis model considering both Shannon Entropy and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. Subjective and objective opinions of purchase managers/experts is turned into quantitative form using Shannon Entropy. TOPSIS technique is used for calculating the supplier’s ratings.
