New sections and chapters are added together with new real-world industry examples, and standards and problems are revised and updated. System Reliability Theory covers a broad and deep array of system reliability topics, including: <ul> <li>In depth discussion of failures and failure modes</li> <li>The main system reliability assessment methods</li> <li>Common-cause failure modeling</li> <li>Deterioration modeling</li> <li>Maintenance modeling and assessment using Python code</li> <li>Bayesian probability and methods</li> <li>Life data analysis using R</li> </ul> Perfect for undergraduate and graduate students taking courses in reliability engineering, this book also serves as a reference and resource for practicing statisticians and engineers. Throughout, the book has a practical focus, incorporating industry feedback and real-world industry problems and examples.
