摘要:
针对航空产品研制过程中设计部门与制造部门分离,研制流程多为单向串行,导致出现复杂航空产品研制周期长、质量低的现状,分析了复杂航空产品的研制流程,建立航空产品成熟度模型,对其研制过程中的重要环节和状态节点进行定义。在此基础上,提出基于成熟度模型的航空产品研制流程控制技术,该技术采用成熟度计算取代原有的阶段评审,实现研制流程的跳转控制和制造部门介入的节点判定。设计基于二级模糊综合评价的航空产品研制成熟度等级评价方法,实现航空产品研制成熟度的多层次多因素评价。为了验证上述方法的有效性,将其应用于某型号航空产品的研制过程。采用上述方法后,制造部门能够有效地提前介入并开展研制工作,实现基于制造成本节约的并行工程,达到缩短研制时间,保证研制成本可控且产品质量稳步提高的目的。

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.
Key words:  aviation  concurrent engineering  product maturity  fuzzy comprehensive evaluation
