Maintenance Strategy

Chapter 1 takes the systems view of a company and explains that the maintenance sub-system influences - and is influenced by - many other sub-systems. It emphasises that the capital asset management function has a major effect on the maintenance department via its concern for asset reliability and maintainability and also that, as regards organisation design, the maintenance and production departments are inseparable. Chapter 2 looks at the influence of capital asset acquisition policy on maintenance life cycle costs. Via an industrial case study, Chapter 3 then develops the overall methodology of BCM. Chapter 4 shows how an industrial plant can be modelled as a hierarchy of inter-related parts and also as a process flow. Chapters 5 and 6 then explain how statistical techniques can be used, firstly to model patterns of component failure and quantify component reliability, and secondly to model and assess the reliability of plant systems. As well as showing how business needs determine the development of maintenance objectives. Chapter 7 also outlines a hierarchy of such objectives. chapter 8 then deals with what is probably the key issue in this area, via preventive maintenance decision making, discussing the concepts and principles involved and their application to the formulation of a life-plan for a unit of plant. Chapter 9 outlines the unique TDBU approach to formulating a preventive maintenance schedule for a plant and Chapter 10 then describes a reliability-based model for controlling the application of maintenance effort. To further illuminate the ideas which have been discussed up to that point, and to reinforce understanding of them, Chapters 11 and 12 present various contrasting industrial case studies and exercises. Finally, Chapters 13, 14 and 15 firstly review the merits and limitations of the two other basic philosophies of maintenance strategy formulation, viz Reliability Centred Maintenance (RCM) and Total Productive Maintenance (TPM) and then compare and contrast them with BCM.
