| Summary: | 碩士 === 淡江大學 === 管理科學學系碩士班 === 100 === In the rapidly changing market, the manufacturers are facing unprecedented competitive pressures. The life cycle of a product is getting shorter in this highly competitive condition, so the companies must make the product to enter the market within a very short time in order to maintain their competitive advantage. Thus, an integrated decision analysis model of form, function, feature, specification, and economic benefits evaluation of a product is needed for a design alternative plan which is constructed from customer’s need to product concept formation, selection and testing of the concept development process. To develop a planning model for new product design and development to achieve the anticipated goal of optimum product design and enhancing the effectiveness of development is the motivation and purpose of this study.
This study integrates the Fuzzy Delphi Method (FDM), Theory of Inventive Problem Solving (TRIZ), Analytic Network Process (ANP), and Zero-one Goal Programming (ZOGP) in the concept development of product design and development to construct a decision analysis model for concept evaluation. The construction of model first begins with questionnaire for the customer’s need that is the key information and structuralized the customer’s need by factor analysis. FDM expert questionnaire is adopted to select evaluation rules with highly consensus. Then TRIZ is used as conflict testing tool and the basis of conceiving innovative method for product design and produce innovative concept plan. A hierarchical relationship of the properties of the target and the rule is established. In the meanwhile, the effect of contradiction between the impacts of each rule property is considered to expand into network architecture. Continuing application of ANP made a pair comparison to obtain the comparative weights to sorting the weights of new product design alternative plan. The obtained value of weight is then introduced into the formula of ZOGP to resolve the optimum plan under the planning and restriction of optimum resource distribution.
In this study, an empirical analysis in the case of the function design of Tablet PC is used to verify the product design and development process and establish concept development process model to provide the decision-maker of the corporation to select an optimum design plan with substantial benefits.
