To determine "to maintain a construction machine of any one machine type more preferentially than a construction machine of other machine types" by comparing data between the construction machines of different machine types in accordance with the same criterion.

For each type of construction machine, a plurality of abnormality determination items to be determined are set and a point is allocated for each abnormality determination item beforehand (101). Each time an abnormality is determined, a numerical value is calculated by converting the point allocated to a determination item of the corresponding abnormality into a ratio of one abnormality determination item with respect to the number of all the abnormality determination items being set to a corresponding construction machine, and a current cumulative point of the relevant construction machine is calculated by adding the calculated numerical value to a cumulative point obtained in the past (103). The current cumulative points obtained for a plurality of construction machines are ranked (104) and the construction machines are maintained in accordance with a maintenance priority order corresponding to the ranking of the current cumulative points (105).
