Structured in stand-alone sections and designed specifically for practicing engineers, this book addresses specific reliability and maintainability analysis methods for part design, systems integration, and life-cycle sustainment. Unlike many books on this subject, this one departs from the nearly exclusive use of the exponential probability distribution to characterize failure and demonstrates other probability distributions that more accurately describe the true behavior of failure. Eschewing a more mathematical or statistical approach, it focuses on engineering and emphasizes failure that results from wear-out over the useful life of the part.
