摘要：A quantitative risk asssment system (QRAS) builds a risk model of a system for which risk of failure is being assd, then analyzes the risk of the system
corresponding to the risk model. The QRAS performs nsitivity analysis of the risk model by altering fundamental components a课文日月潭
nd quantifications built into the risk model, then re-analyzes the risk of the system using the modifications. More particularly, the risk model is built by building a hierarchy, creating a mission timeline, quantifying failure modes, and building/editing event quence diagrams. Multiplicities, dependencies, and redundancies of the system are included in the r英语歌
