Abstract
In the product development process, the marketing personnel and the R&D engineers usually rely on their past vague experience to analyze the relationship between product attributes and engineering design attributes. This may often result in the problem that the engineering attributes can not properly respond to customer requirements. Therefore, in order to achieve the economic goal, both customer requirements and engineering design attributes must be taken into consideration in the evaluation of a new product. Also the ability to confirm the final requirements needs to be developed for the purpose of rapidly creating the needed product. In order to achieve this purpose, it’s not only the problem of marketing or the problem of design or manufacturing, it’s a task which requires the cooperation of different functional departments. This study tries to combine the QFD method and fuzzy theory to treat customer requirements and to establish the relationship between product attributes and engineering attributes. Finally, using the relationship between customer requirements and engineering requirements, the optimal engineering design requirements can be found, the importance factors can be given, and the most appropriate engineer design requirements can be selected. The proposed method can be used in the design and construction of a new product.In order to verify the practicability of the method, the development of commemorative medals of the Central Mint in Taiwan is taken as an example, the steps of the proposed method were followed. The result shows that the proposed method can effectively help the development of a new product.
