Abstract
A control system includes a risk management control unit, an input unit, an execution system unit, and an evaluation unit. The evaluation unit detects gain in line with expected target characteristic and risk contrary to the target characteristic as a result of control. The detected gain and risk are processed in the probability dimension, and histograms indicating occurrence probabilities are generated. By grasping the gain and risk in the probability dimension as the system reliability, the risk management control unit determines the risk and decides a cyclic, growth process. The risk management control unit carries out risk management by detecting a sign of abnormality or the like, based on the system reliability with the gain and risk detected by the evaluation unit being taken in the probability dimension.
