Abstract:

In this study, for a white-goods manufacturer, supplier selection problem is discussed and Axiomatic Design (AD) method is proposed for the solution of the problem. AD is one of the multi attribute decision methods (MADM) that can be used for the solution of the problems which require to be considered both qualitative and quantitative factors at the decision process. In this study, an application of selecting the supplier which has minimum information content among the alternative supplier firms by a hierarchical supplier selection model which is designed based on the important criteria for decision maker has done based on the Information Axiom of AD. Since, all of the factors that affect supplier selection process can not be denoted by numerical values, the evaluation of the firms has been done by using triangular fuzzy numbers and fuzzy AD has been used for the evalution. Also, weighted AD has been used by regarding that factors have precedency with respect to each other and results of both methods have been compared.
