<p>PROBLEM TO BE SOLVED: To easily predict a maintenance charge. SOLUTION: This device is equipped with a database 70 in which standard maintenance time specifying maintenance periods of respective portions of machines are stored by machine kinds, maintenance time read-in means 21 to 23 which read in the standard maintenance time of an object portion of an object machine WM from the database 70, input means 21 to 23 which inputs operation conditions of a customer to the object machine, and arithmetic means 21 to 23 which correct the standard maintenance time according to the operation conditions of the customer and computes a future standard maintenance time meeting the operation conditions, and predicts the maintenance charge based upon the target maintenance time according to the repair cost of the object portions.</p> |
