概要
For accomplishing the safety of a large-scale engineering plant, the common approach is to suppose various emergency situations and prepare in advance effective measures. However, there may happen an unanticipated event. Therefore, it is very important to generate support information of operators to take responsive actions. The previous study developed a technique to generate plausible operation procedures for an emergency situation based on a functional model. Although the algorithm produces some plausible counter operation procedures, it does not indicate which counter operation procedure should be suitable. It is desirable for operators that the technique can prioritize the counter operation procedures produced. This study investigates the indices to prioritize counter operation procedures produced. The indices are listed up considering the viewpoint of the risk assessment. The indices include the effects of executing counter operation procedures, the required time of executing a counter operation procedure, the influence on the environment, and so on.
