10.3.1 General 概 要
The following paragraphs discuss different approaches to the determination of
probability. For the purposes of the discussion, these approaches have been

that “qualitative” and “quantitative” are the end points of a continuum rather
than distinctive approaches (see Figure 3). Most probability assessments use a
blend of qualitative and quantitative approaches. 大 多 数 概 率 评 估 使 用 混 合 , 定

The methodology used for the assessment should be structured such that a
sensitivity analysis or other approach may be used to assure that realistic,
though conservative, probability values are obtained (see 12.4).
