A Study of Proportional Hazards Models: Its Applications in Prognostics
Prognostics and health management technology is proposed to satisfy the requirements of equipment autonomous maintenance and diagnosis, which is a new technique relying on condition-based maintenance. It mainly includes condition monitoring, fault diagnostics, life prediction, maintenance decision-making, and spare parts management. As one of the most commonly used reliability statistical modeling methods, proportional hazards model (PHM) is widely used in the field of prognostics, because it can effectively combine equipment service age and condition monitoring information to obtain more accurate condition prediction results. In the past decades, PHM-based methods have been widely employed, especially since the twenty-first century. However, after the rapid development of PHM, there is no systematic review and summary particularly focused on it. Therefore, this chapter comprehensively summarizes the research progress of PHM in prognostics.
