Preventive maintenance opportunities for large production systems

Traditionally, production and maintenance two major objectives of manufacturing systems are not coordinated. Production is often interrupted by pre-scheduled preventive maintenance (PM) without considering the throughput target, and PM tasks are not cost-effectively conducted. This paper investigates the extra hidden opportunities for PMs during production time without violating the system throughput requirement. We develop a prediction model to identify such PM opportunity windows for large production systems based on real-time factory information system data. (c) 2015 CIRP.
