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.

9.3 System with Multiple Types of Component Local Failures

Some system components may experience multiple types of LFs. For example, a sensor in a WSN system can undergo two types of LFs, which respectively disable the transmission and sensing function of the sensor node. Correspondingly, they are referred to as transmission LFs and sensing LFs. A relay is subject to only transmission LFs based on its function performed. Both sensors and relay nodes may undergo PFGEs due to jamming attacks. They are launched by continually transmitting interference signals so as to block other WSN components, crashing the entire system [7]. Since the jamming attacks depend on the transmission function of the compromised component, the PFGE and transmission LF of the same component are disjoint or mutually exclusive. However, the PFGE and sensing LF of the same component are s‐independent. Figure 9.12 summarizes the s‐relationship among the different types of component failures.
