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.

8.1 Overview

A propagated failure with global effect (PFGE) that originates from a system component causes the failure of the entire system [1]. As one type of common‐cause failures (CCFs), PFGEs have been investigated intensively in literature (see, e.g. [26]). Examples of causes for PFGEs include imperfect coverage (IPC) and destructive effects. Specifically, as discussed in Chapter 3, due to the IPC, a component fault, if not being detected or located successfully by the system recovery mechanism, may propagate and cause an overall system failure even when adequate redundancy remains. Certain types of failures originating from a system component can cause destructive effects on other components, for example, fire, explosion, overheating, blackout, or short circuit may incapacitate or destroy all other system components, causing the failure of the entire system.

However, it is not necessarily always the truth that a PFGE causes the entire system failure, particularly...
