A Grey-Based Approach to Suppliers Selection Problem.

Abstract

Abstract The suppliers selection is a multiple attribute decision making (MADM) problem. Since the decision maker (DM)s like preferences on alternatives or on attributes of suppliers are often uncertain, and thus the selection of good suppliers becomes more difficult. Grey theory is one of the methods that are used to study uncertainty, it is superior in mathematical analysis of systems with uncertain information. In this paper, we proposed a new grey-based approach to deal with selection problem of suppliers. The work procedure is shown as follows briefly: First, the weight and rating of attribute for all alternatives are described by linguistic variables that can be expressed in grey number. Second, proposed grey possibility degree to determine the ranking order of all alternatives. Finally, an example of selection problem of suppliers was used to illustrate the proposed approach.
