The textbook Reliability Engineering: A Handbook focuses on the foundational principles of reliability from an engineering perspective, presenting complex concepts in an accessible manner. It targets B.Tech. and M.Tech. students, research scholars and professionals, equipping them with essential methodologies for maintaining the reliability of engineering systems.
The textbook begins with an introduction, providing a conceptual framework and historical context. Key reliability measures, metrics, and indicators are then discussed, followed by an exploration of system reliability, emphasizing analysis and improvement. Redundancy techniques are presented as strategies for enhancing reliability, alongside Markov analysis for redundancy without repair.
Design for reliability is covered extensively, integrating reliability considerations into the design process. Reliability allocation guides the distribution of reliability targets among components. Fault-tree, event-tree, and failure modes analyses are introduced for failure identification and assessment. Complex systems’ reliability evaluation is supported through standards and methodologies such as load- and strength-based evaluations under varying conditions.
The text also delves into engineering maintenance, discussing proactive strategies, maintainability, and availability to ensure system uptime. Software reliability is examined along with techniques like life testing, accelerated life testing, and highly accelerated life testing. Finally, the economics of reliability engineering highlights the cost implications of reliability decisions.
Reliability Engineering: A Handbook offers detailed examples of core principles, essential techniques, and proven best practices in reliability engineering. The text also emphasizes the critical role of economic considerations, guiding students to balance reliability objectives with cost-effectiveness in their engineering decisions.
Target Audience:
B.Tech., M.Tech. students, research scholars and professionals.
