MAINTENANCE OBJECT MANAGEMENT DEVICE AND PROCESSING METHOD AND PROGRAM OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a maintenance object management device that, taking replaceable components to be prematurely replaced depending upon an operation form or the like of a maintenance object device into account, can manage a stock quantity and a production quantity of the replaceable components.SOLUTION: A maintenance object management device performs the steps of: calculating a cumulative period of time of a reference operation period of time for each of replaceable components constituting a maintenance object device; calculating a predicted reference operation period of time indicating a period of time when the maintenance object device is operated in an operation form serving as a reference until next replacement timing; calculating a number of replacement components of the replaceable components in each of which an operation period of time obtained by adding the predicted reference operation period of time to the cumulative period of time of the reference operation period of time of each of the replaceable components exceeds a life period of time for each of the replaceable components; calculating a number of replacement components of the replaceable components in each of which the operation period of time does not exceed the life period of time on the basis of a relation between the operation period of time until the next replacement timing and a discard ratio of the replaceable components corresponding to the operation period of time; and managing a production quantity and a stock quantity of each of the replaceable components on the basis of the number of replacement components.
