Abstract :

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
