摘要: 为应对逐渐增多的用户需求给“需求满足型”的逆向设计带来的挑战,将基于模型的系统工程应用于“安全注入系统”架构设计,设计过程包括需求分析、功能分析和设计综合。通过需求分析过程的时序图和需求图获取系统需求,并建立需求间追踪关系,便于需求变更影响性分析;通过功能分析的活动图、状态图和时序图实现系统功能架构设计及早期验证与确认;通过设计综合过程的权衡分析优选关键功能备选方案,并借助块定义图展示系统架构模型和动态运行过程,确保所设计的系统满足利益攸关者期望。应用结果表明,基于模型的系统工程(MBSE)适用于现有核电设计,可有效改善传统设计中存在的问题。

Abstract: In order to deal with the challenges brought by the increasing user requirements to the “requirements-satisfying” backward design, in this paper, the model based system engineering is applied to the architecture design of “safety injection system”. The design process includes requirement analysis, function analysis and design synthesis: the system requirements are obtained through the sequence diagram and requirement diagram of the requirement analysis process, and the tracking relationship between the requirements is established to facilitate the impact analysis of requirement changes. The system function architecture design and early verification and confirmation are realized through the activity diagram, state diagram and sequence diagram of the function analysis. Through the trade-off analysis of the design synthesis process, the key function alternatives are selected, and the system architecture model and dynamic operation process are displayed with the help of block definition diagram to ensure that the designed system meets the expectations of stakeholders. The application results show that model-based systems engineering (MBSE) is suitable for the existing nuclear power design and can effectively improve the problems existing in the traditional design. -
