摘要
产品方案设计结果是产品研制的主要依据,其发放过程主要依赖于成熟度进行管控。为了加强对产品方案设计阶段的有效管控,针对方案设计阶段运用基于模型的系统工程方法(MBSE)构建模型的过程中,缺少成熟度量化评估方法的问题,提出一种系统工程模型成熟度模型评估方法,用以量化方案设计过程中系统工程模型成熟程度。在产品方案设计系统工程模型的基础上,建立包含有构建成熟度与迭代成熟度的系统工程模型成熟度模型,进一步对设计元素完成率及需求覆盖率进行评估,并以百分比的形式给出方案设计系统工程模型成熟程度。通过对航天器方案设计阶段环控系统方案设计阶段进行成熟度评估,验证了该方法的可行性。
The product scheme design,delivery of which relies greatly on the maturity management,is the main basis of product development.In the process of the methodology to model based system engineering(MBSE)in the scheme design to model,there is a lack of quantitative evaluation method for maturity,as far as the author is concerned.To strengthen the effective control of the scheme design,a maturity evaluation method with system engineering model was proposed in this paper.Based on the system engineering model in the scheme design,a system engineering model for maturity including establishment and iteration of maturity was established.The design elements are utilized in the maturity model,evaluating the completion rate of the design elements and the coverage rate of requirements,and the maturity of system engineering model in the scheme design is finally given by percentage form.The application in environment control system of spacecraft scheme design shows the effectiveness of the present method.
