PURPOSE:To determine more adequate corresponding operation in case of abnormality occurrence by finding quantitatively the degrees of attainment of respective targets constituting a target attainment network, deciding on an abnormal node, and displaying the results of them on a CRT. CONSTITUTION:An abnormal node decision device 7 compares the degree of attainment of each node which is found by a target attainment degree calculating device 6 with a predetermined boundary, value, and decides on the occurrence of abnormality when the former the degree of attainment is less. The processing result and collected data of a target attainment degree calculating device 6 and the abnormal node decision device 7 are all inputted to a computer 3 and displayed on the CRT 4 fitted to a plant monitor board 5. The relation between the final target of a plant and a low-priority target for attaining the target is grasped objectively on the CRT screen and the various degrees of attainment are known quantitatively, so useful judgment information is obtained. |
