preventive maintenance scheduling is to perform a series of tasks that prevents or minimizes production breakdowns and improves the reliability. mathematical models have been developed to solve the preventive maintenance scheduling problem. there are several limitations in the prior work in this area of research. craft combinations are assumed to be given. the craft combination problem concerns...

RCM evolved during the 1950s in the aircraft industry as a result of a number of major reliability studies concerning complex equipment. In particular, the 1960 FAA / Airline Industry Reliability Program Study was initiated to respond to rapidly increasing maintenance costs, poor availability, and concern over the effectiveness of traditional time-based preventive maintenance. This, like severa...

In some companies, corrective maintenance is conducted in-house but preventive maintenance might be outsourced. This raises a need to optimise some parameters such as the number of contracts from a perspective of the equipment owner. This paper considers a maintenance policy for such a situation, analyses the roles of the parameters in a PM model, proposes approaches to defining bonus functions...

This paper explores the impact of the size of a staff of equally trained maintenance technicians on the productivity of a serial production line. First, we use the reliability and maintainability characteristics of the line to derive optimal preventive maintenance (PM) policies for each unit of equipment. Second, we use simulation modeling to evaluate the performance of the line assuming all re...

Flexible manufacturing cells (FMCs) often operate with increasing failure rate due to extensive utilization and wear-outs of equipment. While maintenance plans can eliminate wear-out failures, random failures are still unavoidable. This paper discusses a procedure that combines simulation and analytical models to analyze the effects of corrective, preventive, and opportunistic maintenance polic...

Computerized maintenance management systems (CMMS) are required to manage and control asset, plant, and equipment maintenance in today’s hospitals. A CMMS is much more than just a way to schedule preventive maintenance (PM). By using a CMMS, you can create equipment logs to record events associated with a piece of equipment; create work orders automatically according to a schedule or manually f...
