VV&A是风险驱动的,FMECA是常用的风险分析方法。将两者进行结合,提出一种面向建模与仿真的FMECA方法——SimFMECA。首先对FMECA分析表格和过程进行扩展,然后分析一般仿真系统的FMI(Failure Mode Identification)框架,并给出风险和危害度评定方法,由此确定所需的VV&A投入,包括VV&A等级以及必需的VV&A活动,最后给出该方法的应用实例。SimFMECA是一种定性的方法,具有花费成本低和易于实施的特点。
VV&A is risk-driven activity, and FMECA is a widely used risk analysis method. Based on them, a new method, aiming to M&S (Modeling and Simulation) domain and named SimFMECA, was put forward. Firstly, FMECA analysis table and process was extended, then a framework of FMI to general simulation system was discussed, moreover, a risk and criticality ranking measure was proposed, and according to the risk rank, required VV&A effort was identified, including VV&A level and W&A activities. Finally an experiment was carried out to validate SimFMECA. SimFMECA is a qualitative method, and is characteristic of low cost and easy implementation.
