A task health measurement method based on complex equipment working time prediction

This paper analyzes the development of PHM technology in mechanical, electronic and other systems. Based on the life prediction ability of the PHM (prognostic health management) technology and task decomposition of complex equipment system, a quantitative method combining set pair analysis for evaluating the degree of task health is obtained. A specific case is analyzed based on this approach. At last, the characteristics and limitations of the method are also summarized.
