In today's global competitive market, a firm, in order to survive and to succeed, needs to improve its competitive edges to meet rapidly changing technological innovations and dynamic customer needs. A well-constructed and reliable supply chain can ensure the success of products in terms of product quality, performance, delivery and cost, etc. As a result, the supplier evaluation and selection process is important, and it must be implemented appropriately to maintain a highquality and long-duration buyer-supplier relationship. In this research, an integrated supplier selection model is proposed. The model applies the decision making trial and evaluation laboratory (DEMATEL), the analytic network process (FANP) and the fuzzy set theory. The DEMATEL can be applied to determine whether there are interrelationships between two factors, whether the interrelationships are significant, and whether the relationship between two factors is two-directional. Thus, it can be used to determine the relationships among the aspects and among the criteria. Instead of prioritizing aspects, criteria and suppliers based on linear thinking using a point scoring scale, ANP is applied so that the aspects, criteria and suppliers can be pairwise compared by experts in a systematic way to ensure consistency in experts' opinions. By applying ANP, the interrelationship among the aspects and among the criteria can be evaluated too. Because the DEMATEL is applied first, the relationships that are not very significant do not need to be considered. Thus, the number of pairwise comparisons in the ANP can be reduced substantially. The adoption of the fuzzy set theory to the DEMATEL and the ANP is to incorporate the fuzziness and uncertainty in the information contents of the experts when filling out the questionnaires. A case study is examined using the proposed model to rank the suppliers. The proposed model can provide references for firms in supply chain management, and it can be tailored to meet the requirement of the firm in the decision-making. [ABSTRACT FROM AUTHOR] |
