A health status evaluation based on minimal path about the destruction equipment of high-risk hazardous goods

摘要

The destroying tasks of high-risk hazardous goods have a strict request to the health status of destruction equipment. This paper proposes health status evaluation method for the polymorphic system based on minimal path theory. With the help of minimal path theory, the model of destruction equipment is analyzed. The health status of the components is predicted by the Markov process theory. According to the different states of the components, the reliability of the polymorphic subsystem is estimated. Finally accordance to the health status classification method based on mean time between failures (MTBF) for the destruction of equipment, health status of the system is determined. This paper provides a way to assess the health status of the device.
