<p>A first service life prediction unit 311 predicts the service lives of main components, such as an engine, based upon their actual wear states. A second service life prediction unit 312 predicts the service lives of the same components, based upon their cumulative load amounts. An order setting unit 320 selects the shorter predicted service lives and sets a priority order for overhaul based thereon. An overhaul schedule table generation unit 330 creates a schedule table D1 based upon this priority order. The contents of this schedule table D1 are corrected, if necessary, by a correction unit 341. A plan creation unit 350 creates an overhaul implementation plan document D2 and the like, based upon the corrected schedule table D1a. The result of the overhaul task and the present states of components are tested, and these test results are reflected by the service life prediction units 311 and 312.</p> |
