New Product Development by Evaluating and Ranking Technical-Engineering Requirements Based on a Combined Approach of QFD, DEMATEL - Fuzzy ANP and DEA Methods.

Abstract

Nowadays, with regard to the competitiveness of the global trade and the need to meet the demands of customers, and given the increasing growth of technology in order to preserve and maintain the organization, we can use the various combinations of QFD as a powerful tool in quality engineering. . In this research, Delphi method was first used to identify the main components of the research including customer requirements and technical requirements, and then, due to the importance of weighing in the quality performance development tool, by developing a combined DEMATEL-ANP fusion decision method, and The severity of the relationships will affect the effectiveness and effectiveness of the components and weights associated with them to complete the matrix of the quality house. In order to complete the QFD method, we will use the new expansion of the Wasserman relationship. Also, in order to solve the traditional QFD problem of not considering the effect of constraints on technical engineering requirements, we will apply a combination of QFD, DEMATEL-Fuzzy ANP and DEA methods in the present study. Also, to demonstrate the effectiveness of this approach, we will consider it as a case study at the Goldiran Industry Corporation's executive washing machine production site.
