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.

Modular Imperfect Coverage

A hierarchical system (HS) is a system whose underlying architecture can be characterized by multiple layers, with each layer housing different modules and/or components. In an HS, the failure behavior of an upper level often relies on the failure behavior of its lower level(s) [1,2].

Chapter 3 focuses on the traditional kill‐all imperfect fault coverage, where an uncovered component fault can lead to the failure of the entire system even when adequate redundancies still remain [3,4]. In an HS, however, the hierarchical nature of the system may aid in the fault coverage [ 2 ,5]: if an undetected fault escapes from one level of the system, it may be tolerated at a higher level. In other words, the extent of the damage from an uncovered component fault in a certain layer of a system does not necessarily cause the entire system loss. On the other hand, a fault can cause the entire system to fail only if it remains uncovered through all levels of the system...
