A hybrid MCDM approach for ranking suppliers by considering ethical factors

subject

description

One of the negative effects of cooperating with un-ethically behaving suppliers is that it may devastate the companies' credibility among employees, customers and the public. In this paper, a hybrid Multiple Criteria Decision Making (MCDM) approach (Disjunctive-WPM method) is proposed to resolve this limitation. The proposed methods consist of the following steps: 1. drop unethical solutions and 2. rank the remaining solutions. Therefore, the aim of this paper is the application of the DisjunctiveWPM method to supplier selection problem by adding ethical factors into the analysis. In addition, a comparative analysis to the traditional WMP method is carried out. The proposed method appears to be more satisfactory than the traditional method in solving this kind of decision problems. The main findings of this study confirm the applicability of the proposed approach.
