A repair component is specified based on repair request information including at least failure information of a product to be repaired and a desired repair fee. A component information database and an owner information database are searched based on the specified repair product, whereby component providing candidates owning a product including the repair component are selected. A purchase reference price is input based the desired repair fee to notify the component providing candidates of the purchase reference price. An evaluation value is calculated which is an index for evaluating a residual value of the repair component on the component providing candidate basis from selling component information containing a desired selling price, and a component providing candidate that provides a repair component having the highest evaluation value is selected as a component provider. A repair fee is input, and the repair requester is notified of repair information containing the repair fee.
