Reliability Centered Maintenance in Industrial Planning - A Case Study

Maintenance planning and scheduling is one of the most efficient investments an industry can make to improve productivity and availability, at the same time to ensure safe working environment at the minimum operating cost. This paper discusses a general approach to develop Reliability Centered Maintenance plan for any system, with the help of a case study of a drag chain conveyor system. RCM is a recently unfolded maintenance strategy with the basic goal of maximizing reliability and availability. This is achieved by incorporating all traditional maintenance strategies and implementing specific policy on each of the assets of the facility. The process involves identifying individual systems or functions and addressing any possible issues ahead of time, using methods like FMEA or FMECA. From the operating history and failure details of the system, approximate life and reliability at any time can be estimated using statistical methods. RPN is calculated from the assessment of risk of failure, and is used to identify critical equipment and prioritize failure modes. Careful analysis of all the results helps in identifying the best suitable maintenance strategy for individual components. The paper further discusses the method of deducing the optimum interval for preventive maintenance tasks, based on reliability data. Keywords - Maintenance, RCM, RPN, FMEA, FMECA, Conveyor System
