Reliability-centered Intelligent Maintenance Decision-making Model

Reliability-centered maintenance is an internationally common systematic engineering approach,which is used to determine the preventive maintenance requirements and optimize maintenance management system.Different from the traditional breakdown maintenance,time-based maintenance,condition-based maintenance,and other maintenance management modes,it can help to avoid "insufficient or excessive maintenance".According to the characteristics of management over equipments in petroleum and chemical industries,a reliability-centered intelligent maintenance decision-making model is established and utilized to guide equipment maintenance.Results show that this strategic maintenance plan bears the property of being more purposeful,and the maintenance tasks can be more scientific.
