Abstract
Maintenance due times of components of a machine are determined according to the status of user-performed in-house maintenance and according to the occurrence of abnormalities during machine operation. A subtraction point (20 points) associated with an abnormality (overheating) detected during machine operation is subtracted from the score (80 points) of a corresponding component (engine) in the machine. An addition point (50 points) associated with the type of maintenance (overhaul performed by in-house maintenance) indicated in maintenance information is added to the score (80 points). Thus, at the time where the value resulting from subtractions from and additions to the score for that component (engine) reaches a prescribed value (10 points) indicating maintenance due time, it is determined that the maintenance due time for that component (engine) has been reached.
