Maintenance functions have long been neglected in Indian industry. A few decades ago, there was a dearth of trained and motivated personnel as the job of maintenance used to be undermined earlier. But now, with the rapid progress in industrialisation, the outlook has changed and maintenance is now considered as a ‘profit centre’.To keep pace with the present market we have to manufacture and deliver goods and services which are on par with internationally accepted standards of quality. This book deals with the subject of maintenance management in detail. It includes topics on energy management, reliability, quality, and operation research as also important aspects in the context of the 21st century, such as total productive maintenance, maintenance information system, and application of computer in maintenance.
