Abstract
The present invention intends to provide a risk management system that can accurately extract information necessary for analysis of a variety of accidents in which a machine is involved. For this purpose, a controller calculates a main risk that is the degree at which a main factor of an accident contributes to the occurrence of the accident on the basis of an evaluation value of the main factor, and calculates a subsidiary risk that is the degree at which a subsidiary factor of the accident contributes to the occurrence of the accident on the basis of an evaluation value of the subsidiary factor. Furthermore, the controller calculates, as the occurrence risk of the accident, an integrated risk that has a value equal to or larger than the main risk and increases or decreases at a degree lower than the degree of increase or decrease in the subsidiary risk, and, when the integrated risk has exceeded a predetermined threshold, causes a recording device to record parameters measured by measuring devices in a certain time period including a clock time at which the integrated risk has exceeded the predetermined threshold.
