Warranty-terms setting system and warranty-terms setting method

A computer-executable warranty-terms setting method, the method comprising:

• a point-of-determination remaining-lifetime recognizing step of recognizing a time-point-of-determination remaining-lifetime indicative of a remaining lifetime of a subject mobile unit at a point of determination;
• a remaining-lifetime consumption-degree predicting step of predicting a remaining-lifetime consumption degree based on usages on another mobile unit different from the subject mobile unit by a first user who starts using the subject mobile unit after the point of determination, the remaining-lifetime consumption degree being indicative of to what degree the remaining lifetime of the subject mobile unit has been consumed per predetermined period in which the first user uses the subject mobile unit;
• a predicted remaining-lifetime decreasing period calculating step of, based on the remaining-lifetime consumption degree, calculating a predicted remaining-lifetime decreasing period indicative of a predicted period in which a remaining lifetime of the subject mobile unit decreases from the time-point-of-determination remaining lifetime to a predetermined criterion value or lower when it is assumed that the first user uses the subject mobile unit after the point of determination;
• and
• a warranty-terms setting step of setting warranty terms for the subject mobile unit based on the predicted remaining-lifetime decreasing period.
