This classic text has now been completely revised and updated, making it an ideal introductory course in reliability for a wide range of engineering qualifications, including City & Guilds 8030 and HNC/Ds. A new chapter focuses on the role of the microprocessor and microcomputer controller, and the use of algorithms for monitoring system performance. The addition of numerous problems, self-check questions and exam-style questions makes this an extremely useful book for courses with an element of independent study.
