Research On The Product Maturity Of High Reliable Application

Product Maturity refers to the maturity of product design, process, production and application. In recent years, the development of high reliability projects has accelerated, the improvement for product maturity of high reliability applications attracted more and more attention. How to evaluate the maturity of the products, as to find the shortcomings and inadequacies of the current products, which targeted to develop an effective improvement plans, also to improve the product maturity rapidly, has great theoretical and practical significance for the sustainable development of enterprises.Studies on evaluating the Product Maturity of high reliable application is provided in this dissertation. The research focuses on the following items: First, based on the analysis of maturity model and application in both domestic and international, formed the main contents of the product maturity, the product maturity is divided into five levels, also the dissertation proposes a method for further evaluation and promotion;Second, the QFD method is creative introduced to evaluation of the product maturity field, and build the evaluation index system based on the customer needs. The system includes two levels, six first-level indicators and 20 second-level indicators, covering all factors which have great effects on product reliability including design, production, inspection and so on. Besides ,it also provided a path for further evaluation by the conversion of user needs;Finally, considering t complexity and fuzziness of product maturity evaluation for high-reliability applications, fuzzy comprehensive evaluation method is introduced to provide an objective evaluation of an effective quantitative tool,Also a case is given to prove the feasibility of this study.
