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.

Deterministic Common‐Cause Failure

According to [1], common‐cause failures (CCFs) are “A subset of dependent events in which two or more component fault states exist at the same time, or in a short time interval, and are direct results of a shared cause.” There are two types of shared root causes or common causes (CCs): external causes and internal causes. Examples of external causes include floods, lightning strikes, earthquakes, sudden changes in environments, malicious attacks, design mistakes, power‐supply disturbances, human errors, radiations, computer viruses, etc. Internal causes are mainly propagated failures (PFs) or destructive effects like fire, overheating, short circuit, blackout, or explosions originating from some component within the system, which may destroy or incapacitate other system components.

CCFs typically happen in systems that are designed with redundancy techniques based on the use of s‐identical components [2]. It...
