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.

2.3 Fault Tree Modeling

The FT technique was first introduced by Watson at Bell Telephone Laboratories in the 1960s for facilitating an analysis of a launch control system of the Minuteman intercontinental ballistic missile [2]. FT has evolved to be one of the most widely used techniques for system reliability and safety modeling and analysis.

FT is an analytical technique starting with identifying an undesired system event (typically the system considered being in a particular failure mode). Then the system is analyzed to identify all possible combinations of basic component failure events that can cause occurrence of the predefined undesired system event [3]. An FT can graphically represent the logical relationship between the undesired system event and the basic component failure events. It provides a logical framework for comprehending the possible ways in which a system can fail in a certain mode [4].

As a deductive technique, an FT analysis starts with a system failure scenario...
