Abstract:

The improvement of concurrent degree supported by cooperative design leads to redundant reciprocating work.Degree of maturity with instant and numerical indicator is a solution to the drawback.A synthesis fuzzy assessment method was proposed,aiming at the requirements of maturity indicator in airplane cooperative design.The method gave maturity degree of component/part combined physical readiness,perspective satisfaction,implementation framework deviation and increment of design indexes.The technology and process of the assessment method was described in detail,and demonstrated by application in design of a specific airplane component,which showed the reflection of each impact factors.The use case shows that the method conforms to the real value and waving law of maturity degree in design,which can aid cooperative design efficiently.

Key words: maturity, cooperative design, concurrent engineering, evaluation

摘要：

飞机协同设计中并行度的提高带来了冗余反复设计的增加,实时、量化的成熟度指标是这一问题的解决途径。针对飞机协同设计对成熟度指标的要求,提出了一种综合模糊评估方法。该方法依据CPM设计理论,使用零部件的物理完备度、指标符合度、创新度和目标偏离度,评估其剩余的修改程度。在具体描述评估的方法和过程的基础上,将评估方法应用于一个具体的飞机部件协同设计场景,演示其实施过程,并探讨各影响因子在评估结果中的影响情况。最后,通过应用实例说明,该评估方法反映了设计过程中成熟度的真实取值和波动规律,能有效辅助协同设计的展开。
