Application of Fuzzy Analytical Hierarchy Process and Quality Function Deployment Techniques for Supplier's Assessment

Vendor Selection Problem (VSP) has been considered in this paper as an integrated method of Fuzzy Analytic Hierarchy Process (FAHP) and Quality Function Deployment (QFD) in the hygienic company. In QFD method, determining the importance of the "weights" for the customer requirements is an essential and crucial issue. FAHP has been used to determine the importance of the "weights" for Product Designing which incorporates 5 important criteria in a hygienic company namely Cost, Sustainability, Delivery Time, Creativity and Quality in 4 categories such as Commercial, Technical, Strategic, Green needs with 12 sub-attributes. The new approach can improve the imprecise ranking of customer requirements and provides a decision tool that facilitates the vendor assessment and selection. The most significant advantage of this integrated method is using of it as a self-evaluation tool in the organization to determine weaknesses and strengths, so it can help researchers to solve this specific subject for supplier’s selection.
