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.

8.8 Summary

In systems subject to the FDEP behavior, there exist competitions in the time domain between the failure isolation effect (caused by the trigger failure) and the failure propagation effect (caused by the PFGE/PFSE of the dependent components). As different occurrence sequences of the trigger failure and the dependent component PFGE/PFSE can lead to different system statuses, it is significant to address the competing effects in the system reliability analysis. Combinatorial methods are presented for reliability analysis of single‐phase systems with a single FDEP group or multiple dependent FDEP groups, and for multi‐phase systems with a single FDEP group. A CTMC‐based method is discussed for addressing the competing effects in the reliability analysis of multi‐phase systems with multiple FDEP groups.
