PURPOSE:To repair a fault only by operating a selected means by diagnosing the fault state of the device and outputting an actuator means which can remove secondary influence. CONSTITUTION:State data supplied from sensors 1a - 1c are compared with reference data to discriminate whether or not there is the fault and a fault diagnostic part 12 diagnoses the fault state according to qualitative data. When there if the fault, a repair planning part 15 reasons and selects an actuator means for repair according to qualitative data and fault diagnostic knowledge. Further, the secondary influence exerted when the selected means is operated is simulated and when the influence is exerted, it is discriminated whether or not the influence can be removed by an actuator means other than the actuator means. When not, a different means is selected again and discriminated. Then a means which can remove the secondary influence is selected and outputted to an actuator control circuit 5. |
