Engineered systems are prevalent to failures when they are in operation, therefore maintaining their reliability is critical to ensure that they continue to operate safely and reliably for their entire lifespan. However, continuously planning and scheduling their reliability maintenance functions is necessary to improve their operation, availability, and overall reliability. Through a case study, the research study evaluates maintenance strategic approaches on a critical asset in a brick manufacturing process to improve the reliability of the asset for quality production. Based on historic failure analysis, optimized maintenance plans and schedules are derived and implemented on the asset to reduce or eliminate unplanned work.
