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.

3.1 Different Types of IPC

Based on fault‐tolerant techniques adopted, there are three types of IPC [8, 9]: element level coverage (ELC), fault level coverage (FLC), and performance dependent coverage (PDC).

Under ELC, also known as a single‐fault model, each component has a particular fault coverage and is associated with a certain coverage probability or factor. This coverage probability does not depend on status of other components belonging to the same system. Under ELC, effectiveness of the system recovery and reconfiguration mechanism relies on the occurrence of each individual fault. For any particular component fault, the recovery mechanism's success or failure is independent of other component faults occurring in the same system. It is possible that a system can tolerate multiple coexisting single component faults.

Under FLC, also known as a multi‐fault model, the fault coverage probability depends on the number of failed components within a particular...
