Über dieses Buch

This book introduces the reliability modelling and optimization of warm standby systems. Warm standby is an attractive redundancy technique, as it consumes less energy than hot standby and switches into the active state faster than cold standby. Since a warm standby component experiences different failure rates in the standby state and active state, the reliability evaluation is challenging and the existing works are only restricted to very special cases. By adapting the decision diagrams, this book proposes the methodology to evaluate the reliability of different types of warm standby systems and studies the reliability optimization. Compared with existing works, the proposed methods allow the system to have an arbitrary number of components and allow the failure time distribution of components to observe arbitrary distributions. From this book, the readers can not only learn how to evaluate and optimize the reliability of warm standby systems but also use the methods to study the reliability of other complex systems.

Chapter 1. Introduction

Abstract
Reliability is an important quality characteristic. With the development of modern society and economy, people put forward higher and higher requirements for product reliability.
Rui Peng, Qingqing Zhai, Jun Yang

Chapter 2. Related Concepts in Reliability Modeling of Warm Standby Systems

Abstract
From the reliability modeling perspective, the warm standby component can fail both in the warm standby state and the normal working state, and its lifetime in the normal working state may depend on the duration of the warm standby state.
Rui Peng, Qingqing Zhai, Jun Yang

Chapter 3. Reliability of -Out-Of- Warm Standby Systems

Abstract
In real-life applications, the operation of systems requires the simultaneous work of multiple units

Chapter 4. Reliability of Demand-Based Warm Standby Systems

Abstract
In Chap. 3 we present a BDD-based approach for the reliability modeling of k-out-of-n wamr standby systems subject to imperfect fault coverage.
Rui Peng, Qingqing Zhai, Jun Yang

Chapter 5. Reliability of Warm Standby Systems with Imperfect Fault Coverage and Switching Failure

Abstract
The redundant system with warm standby components is still considered in this chapter.

Chapter 6. Optimal Working Sequence in a 1-Out-Of-N Warm Standby System

Abstract
In a warm standby system, the components are working following a predetermined order.

Chapter 7. Reliability Evaluation for Demand-Based Warm Standby Systems Considering Degradation Process

Abstract
Warm standby redundancy is a fault-tolerant technique balancing the low economical efficiency of hot standby and the long recovery time of cold standby.
Rui Peng, Qingqing Zhai, Jun Yang

Chapter 8. Reliability of Demand-Based Warm Standby System with Common Bus Performance Sharing

Abstract
Redundancy techniques have been extensively utilized to enhance the reliability of engineering systems.
Rui Peng, Qingqing Zhai, Jun Yang

Chapter 9. Reliability of Warm Standby Systems with Phased-Mission Requirement

Abstract
In the preceding chapters, we analyze the system reliability under fixed system demand. In reality, the demand can vary with time.
Rui Peng, Qingqing Zhai, Jun Yang

Chapter 10. Reliability of Warm Standby Systems with Complex Structure

Abstract
The redundant systems with warm standby components studied in the previous chapters are all simple parallel structures. In practice, the systems may have more complex structures, such as series-parallel system, consecutive k-n system, linear sliding window system, etc.
