1. A method of managing maintenance for a plant, comprising the steps of:
- (a) grouping structural members of the plant on the basis of a likeness criterion of a predetermined operation status into a plurality of groups; and
(b) installing an index member to be inspected at at least a part of at least one of the structural members belonging to each group, the index member having a higher degradation tendency than the other structural members in the group.

Abstract
Structural members constructing a plant are classified into a plurality of groups on basis of a likeness criterion of a predetermined operation status. An index member having a higher degradation tendency than the structural members belonging to the group is installed at at least a part of at least one of structural member to generate an inspection plan through actual inspection of the index member to provide reduction in the number of structural members to be inspected and an extended inspection interval without decrease in reliability.

10. A method of managing maintenance for a plant comprising:
-
a first step of grouping structural members of the plant on the basis of likeness criterion of a predetermined operation status into a plurality of groups;
a second step of predicting degradation of the structural members belonging to each group to estimate the degradation tendencies;
a third step of selecting at least one of the structural members having a high degradation tendency; and
a fourth step of installing an index member to be inspected at at least a part of at least one of the structural members belonging to each group, the index member having a higher degradation tendency than the other structural members in the group. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
