An overview of time-based and condition-based maintenance in industrial application

An electricity price-dependent control-limit policy for conditionbased maintenance optimization for power generating unit

“…The component degradation process can be described by the 1) proportional hazard model, with covariates observable at each inspection. The components of the system are independent in degradations 2) and failure processes.…”

“…Generally, there are two types of preventive maintenance strategies, i.e. scheduled maintenance and condition-based maintenance (CBM) [1,14,17]. For scheduled maintenance (also called planned maintenance), the PM is carried out in accordance with established time intervals.…”

Maintenance decision-making based on remaining useful life considering economy optimal targets and its application

“…Then its characteristics were analyzed, and the key relationship of maintenance contents and decision-making process were proposed [3]. Therefore, the maintenance decision method was proposed in the application of complex equipment [4][5][6].…”

Design of Condition-Based Decision Support System for Preventive Maintenance

“…Therefore, CBM is needed for better equipment health management, lower life cycle costs, catastrophic failure avoidance, etc. (Ahmad and Kamaruddin, 2012). However, the introduction of CBM without managerial support at all levels, appropriate data and analysis, disciplined and knowledgeable maintenance staff is unlikely to achieve desired results (Ellis, 2008).…”

“…According to Ahmad and Kamaruddin (2012), maintenance strategies can be broadly classified into Corrective Maintenance (CM) and Preventive Maintenance (PM) strategies. Authors further report that the PM concept involves the performance of maintenance activities prior to the failure of equipment.…”
