Abstract

Processes for system failure analysis (for example, FMEA) are structured, well-documented, and supported by tools. Nevertheless, we hear complaints that FMEA work feels (1) too labor intensive to encourage engagement, (2) somewhat arbitrary in identifying issues, (3) overly sensitive to the skills and background of the performing team, and (4) not building enough confidence of fully identifying the risks of system failure. In fairness to experts in the process, perhaps such complaints come from those less experienced — but even so, we should care how to describe this process to encourage better technical and experience outcomes. This paper shows how model-based systems engineering (MBSE) answers these challenges by deeper and novel integration with requirements and design. Just as MBSE powered the requirements discovery process past its earlier, more subjective performance, so also can MBSE accelerate understanding and performance of failure risk analysis — as a discipline deeply connected within the systems engineering process.

故障分析:基于模型的系统工程的启示
系统故障分析流程(如 FMEA)结构严谨、记录详实,并有工具支持。尽管如此,我们还是会听到一些抱怨,说 FMEA 工作(1)劳动强度太大,不鼓励参与;(2)在确定问题时有些武断;(3)对执行团队的技能和背景过于敏感;(4)没有建立起充分识别系统故障风险的足够信心。公平地说,这些抱怨可能来自那些经验较少的专家,但即便如此,我们也应该关心如何描述这一过程,以鼓励取得更好的技术和经验成果。本文展示了基于模型的系统工程(MBSE)如何通过与需求和设计更深入、更新颖的整合来应对这些挑战。正如 MBSE 使需求发现过程超越了其早期的主观表现一样,MBSE 也能加速故障风险分析的理解和表现--作为一门与系统工程过程紧密相连的学科。
