Each scenario will have an associated overall probability of occurrence that will<br />

be lower than the probability of the failure itself so that the POF and COF<br />

should be developed interactively(?). After the scenarios have been<br />

developed and potential consequences estimated, acceptable ways to list<br />

consequences include: 可 以 接 受 潜 在 后 果 , 列 出 方 法 有 ;<br />

• classify consequence into three or more categories (e.g. a five-category<br />

classification system might be very low, low, moderate, high, very high);<br />

分 类 结 果 为 三 个 或 更 多 类 别 - 例 如 一 个 五 级 分 类 制 度 可 能 非 常 低 , 低 , 中 , 高 ,<br />

很 高 .<br />

• rank consequence on a scale (e.g. a scale might be from 1 to 10);<br />

排 名 结 果 - 例 如 的 规 模 可 能 是 从 1 到 10.<br />

• measure consequence (e.g. determine the estimated number of fatalities for<br />

a scenario and the economic losses in monetary units).<br />

测 量 结 果 - 例 如 以 货 币 单 位 的 经 济 损 失 死 亡 人 数 的 估 计 数 .<br />
