Protective Devices

C-MORE is working on an optimal policy for the inspection, repair, and replacement (IRR) of a protective system. In such a system, a single protective system device exists to operate in the case of an emergency incident to prevent undesirable consequences, such as danger to humans, the environment or downstream equipment. Protective systems present a special case, since their failures are hidden and can only be discovered during inspections or in case of an actual emergency. Our method considers maximization of expected interval availability of a protective system during a given interval of time.
