PROMETHEE-II MADM approach for selecting the green supplier
The multi-criteria decision-making (MCDM) method is referred to as a method used for scoring or ranking a finite number of alternatives by considering multiple criteria attached to the alternatives. PROMETHEE is well adapted to the decision problems where a finite set of alternatives is to be outranked subjected to multiple conflicting criteria. This paper proposes a preference of green suppliers using the PROMETHEE-II. Comparable results are presented to check the effect of different preference functions on the final preference. Seven economic and environmental criteria, four suppliers are taken in the green supplier selection problem. The PROMETHEE method begins with an evaluation of alternatives with respect to the criteria. These evaluations essentially need numerical data where their implementation needs information on the relative importance of the criteria and also information on the decision makerís preference functions. The information is obtained when the decision-makers compared the contribution of the alternatives with respect to each criterion. Different types of preference functions have been used in the implementation. The first net outflows and preference order are obtained using the usual criterion preference function, which is considered as the simplest function. The second net outflows and preference order are obtained using the combination of linear preference function and level preference functions. Both of these functions are chosen based on the nature of the criteria. The results are compared to see the impact of different preference functions.
