Research Of New Product Developing Model Based On Quality Function Deployment And Association Rules

Product innovation becomes more and more popular. People are looking for kinds of ways to develop new products. Among which quality function deployment (QFD) applied abroadly in new product development (NPD) because of its special characteristics. When we are applying QFD, we got the weight of left side from the avaragc of all individual’s appraisal of the customer requirements, which was the substitude for the all people. But according to Arrow’s Impossiblity Theorem, this process was not supported. This paper presented the NPD model based on QFD and association rules, which correlates the customer sementation and customer requirements and creatively puts forward the customer segmentaiton house of quality. Not only it simplifies the House of Quality, but also makes newly developing product targeted to some customer. Extracting the according customer requirements based on the customer segmentaion makes the left side of the house of quality, the most important input, more accurate and targeting, and provides the right direction for product improving.In this paper, Affinity Diagram was used to systemize, induce and classify the customer requirements. Fuzzy Analytic Hierarchy Process (FAHP) was used to measure the importance of customer requiirements. The author also used the principle of association rule to select the valued criterio and the according customer types. What’s more, customer requirements value was proposed in this paper to analyze, select and extract customer requirements. Based on what has been done above, customer segmentation house of quality was constructed to transform the custoemr needs to the product design. This NPD model was also applied in a mulitlayerd wood flooring program successfully.The researching findings are:(1) Proposed the new product development model based on QFD and association rule.(2) Proposed the "customer segmentation house of quality" and connected the customer requirement with customer segmentaion.(3) Applied this model in a mulitlayerd wood flooring program in a board company successfully.(4) Creatively put forward the concept of "customer requirement value"...
