针对协同设计活动成熟度进行了研究,提出了一种以“任务的关键支撑要素成熟度系数”为衡量指标的协同设计活动成熟度评价方法,将设计活动分解为若干设计任务,综合考虑完成每项设计任务所必需的支撑要素的重要程度和该要素的成熟度,建立了任务在关键支撑要素方面的成熟度矩阵,定义了设计活动的总成熟度的计算方法,并成功应用该方法将某航天器构型布局设计活动的成熟度提高了18.57%。 This paper studies the maturity of collaborative design activities and puts forward a method to evaluate the maturity of collaborative design activities based on the key factor of maturity of key tasks. The design activity is divided into several design tasks, The degree of importance of the supporting elements necessary to complete each design task and the maturity of the elements, the maturity matrix of the tasks in the key supporting elements, the method of calculating the total maturity of the design activities, and the successful application of the method The maturity of a spacecraft configuration layout design activities increased by 18.57%.
