17.6 Assumptions Made to Assess <strong>Risk</strong> 风 险 假 设<br />

<strong>Risk</strong> analysis, by its very nature, requires that certain assumptions be made<br />

regarding the nature and extent of equipment deterioration. Moreover, the<br />

assignment of failure mode and the severity of the contemplated event will<br />

invariably be based on a variety of assumptions, regardless of whether the<br />

analysis is quantitative or qualitative. To understand the basis for the overall<br />

risk, it is essential that these factors be captured in the final documentation.<br />

Clearly documenting the key assumptions made during the analysis of<br />

probability and consequence will greatly enhance the capability to either<br />

recreate or update the RBI assessment.<br />
