Abstract:
One of the main obstacle to the development process of aviation product is that the separation between the design and manufacturing departments together with the one-way serial mode of design-manufacturing leads to the long development cycle and low quality. This paper analyzed the development process of complex aviation products, established the aviation product maturity model, and defines the important links and state nodes of the development process. An aviation product development process controlling technology based on capability maturity model was presented. This technology replaced the original review by maturity calculation, achieving the control of the development process and determining the nodes for manufacturing sector involved in. An evaluation method for aviation product development maturity level based on the two-level fuzzy comprehensive evaluation method was designed to realize the multi-level and multi-factor evaluation of aviation products maturity degree. In order to verify the effectiveness of this method, it was applied to the development process of a type of aviation product. The results show that the manufacturing sector can effectively get involved in advance to implement the concurrent engineering, which is aimed at saving manufacturing cost by shortening the development time, controlling the development costs and improving the quality of products.
