quality function development (qfd)

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.

Nowadays, achieving continuous improvement and excellence in all aspect of the organization is very important. In this regard, European Foundation for Quality Management (EFQM) helps the organization to go toward the excellence. The aim of the research is to draw an integration model from 360-degree feedback and European Foundation for Quality Management (EFQM) by using Quality Function Development (QFD). The model should be useful in evaluating the performances of the managers of Iranian Poliacril Company and in pursuing excellence in the company. As a result, the existence gap between external performance evaluation and the managers’ self evaluation was analyzed in order to illustrate the strengths and weaknesses of the organization management. In addition, relationships between managers’ performance and organizational performance were established and the priority classification of managers’ performance criteria and that of organization excellence model enablers were determined.

Nowadays, the systematic transfer of customers, demands and comments and converting them to practical measures in line with the modification or correction of the product have become of immense importance for the companies in order to achieve success and competitive primacy . In this regard, companies have proceeded to seek higher levels of quality for their products and services as well as to improve them continually in order to keep up with the rapid pace of progress and change all over the world. The present survey attempts to present a mathematical model for quality function development (QFD) based on fuzzy approach which can consider customers demands and comments. For this purpose, first the demand and desired technical properties were identified by using QFD method. Then, by ANP method, we specified the demands and weighed technical properties as well as the rate of thecorrelation of demand and technical properties. Finally, the idealistic programming model was presented which includes different level of importance of technical needs through the use Fuzzy ANP method, such as limitation of financial resource, rate of feasibility, and degree of competitiveness, which should be considered in the designing phase. In conclusion, in order to test the presented model, we have shown the result of applying the model in a case study related to the production line of “Axel” in “X” industrial manufacturing company.
