| Outline of Final Research Achievements |
Product liability makes it obligatory for manufacturers to provide an appropriate and effective preventive maintenance procedure for each product. However, the international standards on maintenance, such as IEC 60300-3-11, and well-known references in the fields of safety and dependability engineering do not describe an operating state suitable for safely performing preventive maintenance of control systems. In this research project, an operating state suitable for safely performing preventive maintenance of each subsystem of a control system has been theoretically clarified for the first time. Furthermore, a new control system design for achieving the operating state has been proposed, where the safety of the bidirectional transitions between normal operation and the operating state is guaranteed. This preventive maintenance support technology can be some help for Japanese products to enhance global competitiveness.
