Dynamic System Reliability

By: Liudong Xing, Gregory Levitin, Chaonan Wang

Overview of this book

This book focuses on hot issues of dynamic system reliability, systematically introducing the reliability modeling and analysis methods for systems with imperfect fault coverage, systems with function dependence, systems subject to deterministic or probabilistic common-cause failures, systems subject to deterministic or probabilistic competing failures, and dynamic standby sparing systems. It presents recent developments of such extensions involving reliability modeling theory, reliability evaluation methods, and features numerous case studies based on real-world examples. The presented dynamic reliability theory can enable a more accurate representation of actual complex system behavior, thus more effectively guiding the reliable design of real-world critical systems. The book begins by describing the evolution from the traditional static reliability theory to the dynamic system reliability theory and provides a detailed investigation of dynamic and dependent behaviors in subsequent chapters. Although written for those with a background in basic probability theory and stochastic processes, the book includes a chapter reviewing the fundamentals that readers need to know in order to understand the contents of other chapters that cover advanced topics in reliability theory and case studies.

9.5 Summary

This chapter addresses the probabilistic competing failure behavior, which extends the deterministic competing failure behavior addressed in Chapter 8 by considering uncertain or probabilistic failure isolation effects. As demonstrated by the case studies from the Internet of Things applications (WSNs, body sensor systems, and smart homes), the probabilistic competing failure behavior abounds in systems involving relayed wireless communications. Combinatorial methods are presented for reliability analysis of single‐phase systems with a single type of component LFs, multiple different types of component LFs, and random PT. Refer to [11] on a combinatorial procedure for analyzing reliability of single‐phase systems subject to multiple dependent PFD groups. Refer to [12] on addressing the probabilistic competing failure behavior in the reliability analysis of phased‐mission systems (PMSs).
