Reliable Preventive Maintenance Scheduling

Abstract

Abstract Maintenance of goods producing systems is undertaken on the principle of minimum cost whereas the maintenance of service producing systems is done on the principle of operational reliability. High pressure boilers, elevator ropes, aeroplane engines, subway tunnels, suspension bridges, air conditioning and transportation networks are examples of such systems. In this paper, reliability models are built for a service producing system which works intermittently, is subject to wear, and can be improved through maintenance actions like cleaning, lubrication, realignment, etc.-short of replacement. Finally an application is shown and maintenance scheduling is developed through an example.
