Abstract
In a server, a standard setting sectionestablishes a standard amount of deposits and a standard amount of money of a maintenance charge in advance; a first calculating sectioncalculates the maintenance charge by multiplying the standard amount of money by a ratio of a deposition level at returning to a standard deposition level; a memory sectionstores in memory an engine operating time, the number of regeneration sequences performed, and a reduction coefficient table; a second calculating sectionestablishes a reduction coefficient based on the reduction coefficient table and reduces the maintenance charge after reduction by multiplying the maintenance charge calculated by the first calculating sectionby the reduction coefficient; and a third calculating sectioncalculates an amount of refund by subtracting the value of the maintenance charge from the value of a maintenance guarantee.
