Abstract:
Aiming at the disadvantage of periodic maintenance, a condition description model of equipment based on Weibull proportional hazards model (WPHM) is proposed and taken as the foundation for condition-based maintenance (CBM) decision-making. In terms of the most emphasized tasks properties in equipment, CBM actions and condition inspection intervals are studied as the major contents which take the availability as decision-making objective function. The deteriorate process of covariate condition is presented in the form of transition matrix, and the maximized conditional availability is taken as the optimization target to determine the detailed decision-making methods and related algorithm. Finally, a case study is illustrated to verify the feasibility and reasonability of the method.
