Reliability, Maintainability and Risk: Practical Methods for Engineers, Fourth edition presents the techniques in the analysis and assessment of reliability, maintainability, safety, and risk factors in engineering design. The book contains chapters that are devoted to the discussion of reliability parameters and costs; the history of reliability and safety technology; cost-effective approaches to quality, reliability and safety; interpretation of failure rates; and prediction of reliability and risk. Risk assessment, design and assurance techniques, project management, and product liability are tackled as well. Industrial engineers, contract administrators, project managers, designers, and professionals responsible for the design and implementation of engineering projects will find the book invaluable.
