Abstract
Effective reuse of parts is necessary to achieve a sustainable society. However, consumers are often reluctant to use reused parts because those parts are prone to cause failures. It is necessary to offer consumers information on the possibility of failures with reused parts in order to promote their reuse. We are proposing a method for evaluating the usability of a reused part by forecasting its effect on functions of product including the part by comparing it with information gathered from the consumers who uses the same parts. A system is developed for hard disk drive as an example part.
