FUZZY AHP COMBINED WITH IMPRECISE GOAL PROGRAMMING FOR THE SUPPLIER SELECTION PROBLEMS: INTEGRATION OF THE DECISION MAKER\'S PREFERENCES Author(s): Mohamed Anis Allouche ,Tahar Jouili J. Ponte - Sep 2016 - Volume 72 - Issue 9 doi: 10.21506/j.ponte.2016.9.18 Abstract: The purpose of this paper is to suggest a fuzzy optimization approach to solve supplier selection problem which is based on fuzzy analytic hierarchy process (FAHP) and imprecise goal programming (IGP). To deal with the decision-maker (DM) preferences, the concept of satisfaction function is introduced. The proposed approach is applied in a real case, Tunisian Company, in which the DM considers several conflicting objectives simultaneously: maximizing the total value of purchases, minimizing the total cost of product, minimizing the total number of defective product and minimizing the total number of delivered late units. The obtained results show that the proposed approach is very useful for selecting the best supplier, practising and meeting the DM preferences
