METHOD OF MEASURING HEALTH INDEX OF PLANT IN WHICH CONDITION OF LOWER LEVEL COMPONENT IS REFLECTED AND COMPUTER-READABLE STORAGE MEDIUM IN WHICH PROGRAM TO PERFORM THE METHOD IS STORED

摘要

The present invention relates to a method of measuring a health index of a plant in which a condition of a lower level component is reflected and a computer-readable storage medium in which a program to perform the method is stored in which the condition of the plant is more easily and conveniently monitored based on only the health index of the uppermost level layer, in a case in which an actual measurement value of a certain component of a certain lower level layer deviates from a normal range, the actual measurement value is reflected in the health index, and, in a case in which a trip possibility of the plant due to change of an actual measurement value of a specific component is low although the actual measurement value of the component temporarily deviates from a normal range, the actual measurement value of the component has a minimal influence on the health index.
