Multi-criteria Supplier Evaluation Using Fuzzy AHP

In order to ensure the uninterrupted supply of items, the suppliers´ performance needs to be evaluated periodically. The evaluation process typically consists of identifying the attributes and factors relevant to the decision, and measuring the performance of a supplier by considering the relevant factors. But the evaluation process is complex. Linguistic assessment of suppliers may be carried out based on several criteria. Much of the data are difficult to obtain and ambiguous or vague to interpret. Nonetheless, a rational process of evaluation must exist to select the most appropriate suppliers. This paper proposes fuzzy comprehensive method for evaluating the suppliers based on AHP. The method combines AHP and fuzzy theory and provides a comprehensive evolution method for choosing partner of supply chain. Finally a case was applied to qualify its scientific and feasibility.
