Maintainability, Availability, And Operational Readiness

"This handbook provides a comprehensive guide to advance strategies and procedures for this vital function. Once equipment has been purchased, anywhere from four to forty times its purchase price may be spent on maintenance and repairs. The ability to monitor, quantifies, predicts maintenance needs and ensures the highest equipment availability at the lowest cost. Aimed at professional engineers and managers as well as students, the Maintainability, Availability, and Operational Readiness Engineering Handbook, includes problems, learning suggestions, and complete references. Practical examples, and computer programs, provide a thorough treatment.

The study covers the benefits of an integrated reliability and maintainability engineering programme in industry and government with its case histories. It includes maintainability design criteria, test methods to determine maintainability engineering measures and preventive maintenance policies. "

Caterina Cotter holds Ph.D. in Industrial Engineering from Technical University, Aachen.She is a Visiting Professor in several Technical Universities. Her activity ranges over all fields from improvement of quality in industrial processes,maintainability design criteria and maintenance. Her journals and articles deal with the problems concerning with industrial plant engineering, maintenance engineering, effectiveness and reliability engineering concepts, downtime distributions and maintainability engineering functions, restore and repair or replace components in an equipment.She is recognized as an innovator and thought leader in the field of Engineering.
