Research on Key Technologies of Health Assessment for Multi-equipment Production Line

In order to realize the reliable operation of the multi-equipment production line, it is necessary to monitor the overall health status of the production line system to avoid large-scale shutdowns of the production line equipment. The multi-equipment production line has the characteristics of large-scale equipment and complex structure, which bring difficulties to the health assessment of the entire system. Existing research on health assessment at the system level lacks the establishment of a multilevel evaluation system from the equipment level to the system level. Therefore, this article proposes a system health index calculation method based on the importance of data and dynamically set weights for the system health assessment of multi-equipment production lines. This method overcomes the shortcomings of the traditional system health index construction method, and comprehensively considers the health status of most equipment in the production line and the worst health status, so it can more accurately reflect the overall health level of the system.
