Manufacturing systems availability is of fundamental importance to efficient operation. Current ideas on maintenance are quite different from the out-of-date traditional approach of fire-fighting breakdowns. "Condition-based Maintenance" offers the means of efficient operation and is an enabling vehicle for quality assurance. The book covers all aspects of the modern approach both technically and managerially. This book should be of interest to Condition-Monitoring practitioners, industrial engineers, Technical managers in Manufacturing and Maintenance, senior undergraduate/graduate students on Manufacturing/Industrial/Systems engineering courses.
