This book constitutes a comprehensive and up-to-date text on this important topic for students, practising engineers and managers. The second edition consolidates the practical approach established in the first edition. New material is included on the engineering aspects of reliability and environmental testing, repairable system reliability, manufacturing control and production testing, and on maintenance and maintainability. Particular emphasis is placed on proven methods for the development and production of reliable equipment. The mathematical concepts described are limited to those necessary for the solution of the problems covered.
