对修正行为的分析

RESEARCH OF RECOVERY ACTIONS

对于每个事件树及其割集 ,一般要考虑可能的修正行为 ,并且可能有的修正行为是包含在所有的事件割集中的 .重要的是 ,正确理解修正行为包含的内容 ,确定那些修正行为是可行的 ,而且把它加入到模型中是最可能成功的 .当然 ,这些工作都是根据操作人员的输入信息进行的 .修正行为的第一阶段是判断并描述可能的修正行为 ,以及可用的时间限度 .第二阶段是收集所需的数据和信息 ,并估算第一阶段确定的修正行为的概率 .第三阶段是把修正行为加入到事件割集中 。

For each event tree sequency or cut set, several different potential recovery actions may be considered. Usually one is include per sequence or cut set. It is important to understand what is entailed in the recovery actions and decide which, if any, are physically feasible, and incorporate the one most likely to be successful into the model. The choice is, of course, guided by input from the station staff. The identification and description of potential recovery actions complete with their associated time windows. The second stage of teh recovery analysis consists of data/information collection need for, and estimate of the probabilities of the recovery actions that are identified in the first stage. The third stage is incorporation of quantified recovery actions into sequence cut sets, and requantification of the logic model.
