<P>PROBLEM TO BE SOLVED: To suppress the variation of the deteriorating state of a vehicle in a prescribed management target period. <P>SOLUTION: Four vehicles are used in different management environments. Deterioration trends A1-A4 indicating the deterioration progressing conditions of each management environment are calculated from a traveling distance or the like. It is determined that the deterioration trend A1 results in the most the deterioration of the vehicle, and that the deterioration trend A4 results in the least the deterioration of the vehicle from the inclinations of the deterioration trends A1-A4. Then, the deterioration prediction values C1-C4 of each vehicle in a management target period are calculated based on the deterioration trends A1-A4 and the latest deterioration values B1-B4. Then, the vehicle of the largest deterioration prediction value C1 is newly assigned to the management environment of the deterioration trend A4 which results in the least the deterioration of the vehicle, and the vehicle of the smallest deterioration prediction value C4 is newly assigned to the management environment of the deterioration trend A1 which results in the most the deterioration of the vehicle. Also, the vehicle of the deterioration prediction value C3 is newly assigned to the management environment of the deterioration trend A2, and the vehicle of the deterioration prediction value C3 is newly assigned to the management environment of the deterioration trend A3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
