Unplanned downtime is expensive, but simply increasing maintenance is not always the answer. The focus here is on reliability, preventive and predictive maintenance, condition monitoring, CMMS, spare parts and ways to make maintenance resources more effective.
Preventive and predictive maintenance are not competing plant-wide systems. The right approach depends on asset criticality, failure behavior, detectability, data and the cost of acting too early or too late.
Downtime falls when a factory uses one event definition, separates failure frequency from recovery time and attacks the losses that constrain output. This guide provides metrics, a data model and a 90-day improvement plan.
