Risk evaluation system for process system, risk evaluation program and risk evaluation method

摘要

This risk evaluation system for a process system is equipped with: a storage unit, an operation unit, a calculation unit, a risk evaluation unit, and a display unit. The calculation unit calculates first and second factors to be used for risk evaluation related to specific constituent devices of respective processes on the basis of predetermined information about the specific constituent devices. The risk evaluation unit generates device risk evaluation information to be used for displaying a device risk evaluation matrix, including plot images that are defined by two axes comprising the first and second factors and plotted on the basis of the calculated first and second factors of the specific constituent devices. In addition, the risk evaluation unit generates the device risk evaluation information in such a manner as to achieve a display mode in which the plot images of the respective specific devices constituting the same process can be identified from one another.
