S corresponds to the severity of the vehicle. S _j corresponds to the severity of the vehicle when the vehicle is driven under the j severe condition type among j types of other severe condition types. M _ji corresponds to the i-th mileage the vehicle has traveled among the driving ranges where M _j is divided into i sections in j severe condition type. W _ji corresponds to the specific gravity constant of the i-th running section among the running sections divided into i sections in the j severe condition type. C _ji corresponds to the contribution of the i-th driving segment among the driving segments divided into i segments in the j severe condition type.
