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

摘要

A risk evaluation system includes 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 for use in risk evaluation relating to specific constituent devices on the basis of predetermined information about the specific constituent devices. The risk evaluation unit generates risk evaluation information to be used for displaying a device risk evaluation matrix defined by two axes of the first factor and the second factor and including plot images plotted based on the first and second factors of the specific constituent devices. Further, the risk evaluation unit generates the device risk evaluation information in identifiable displaying mode to allow identification of plot images of specific constituent devices constituting a same process.
