Abstract:
A method of determining maintenance due times for a machine on the basis of the operating status, comprising the steps of:giving a score according to reserve time remaining until next maintenance due time to each component of the machine;associating a point to be subtracted from a score of each the component of the machine, for every type of abnormal phenomenon that could occur while the machine is operating, and for associating a point to be added to the score of each the component of the machine for every type of maintenance that would be performed on the machine;detecting abnormal phenomena that occurred while the machine is operating, and inputting information on maintenance that was performed on the machine;subtracting a subtraction point associated with the detected abnormal phenomena from the score of the corresponding component of the machine, and for adding an addition point associated with maintenance type indicated by the maintenance information to the score of the corresponding component of the machine; anddetermining that the maintenance due time for the component has been reached when value resulting from subtraction from or addition to the score for the component of the machine attains a prescribed value.
