| In power plant equipment maintenance activities, with a systematic and intelligent condition-based maintenance decision-making system is the strong support for the maintenance activities to carry out. In this paper, based on the study of the status for the power plant equipment' maintenance decision-making, the improved reliability-centered maintenance theory was proposed, which was compared with the traditional way. And with making full use of the existing theoretical methods, the structure for the maintenance decision was built up as well as the model from three links, which were the way decision for the equipment maintenance and the state decision for the equipment maintenance and the cycle optimization for the equipment maintenance. And finally, the models which made this research have practical value were applied in power plant equipment. |
