This book is dedicated toDr. Thad Regulinski on his 80th birthdayfor his many years of contributionsin Reliability Engineering and profession!
Preface
Growing international competition has increased the need for all engineers and de-signers to ensure the level of quality and reliability of their products before release,and for all manufacturers to produce products at their best reliability level at thelowest cost. This implies that the interest in reliability and quality will continue togrow for many years to come.
This book comprises 25 chapters, organized in five parts: System ReliabilityComputing, Reliability Engineering in Design, Software Reliability and Testing,Quality Engineering in Design, and Applications in Engineering Design. It aims topresent the latest theories and methods of reliability and quality, with emphasis onsystems design, models and applications. The subjects covered include reliabilityengineering, maintenance, quality in design, failure analysis, robust design, soft-ware reliability and engineering, engineering reliability in design, software devel-opment process and improvement, reliability computing, software measurements,software cost effectiveness, applications in reliability design, stress-strength proba-bilistic, statistical process control, stochastic process modeling, repairable systems,safety analysis, accelerated life modeling, probabilistic modeling and risk analysis.Each chapter will be written by active researchers and/or experienced practition-ers with international reputations in the field and with the hope of bridging the gapbetween theory and practice in reliability and quality in design. Authors of manyoutstanding papers from the 12th ISSAT Conference Proceedings of the Interna-tional Conference on Reliability and Quality in Design (2006) have been invited toexpand their conference papers for contribution as chapters to this book.
The book consists of five parts. Part I of the book contains five papers, dealswith different aspects of System Reliability Computing. Chapter 1 by Zeephongsekuldescribes in detail the characteristic of central limit theorem for a reliability mea-sure, called gauge measure, which is based on a marked point process. It also dis-cusses directions of applications related to this new reliability measure. Chapter 2by Tian, Li, and Zuo discusses a recent advance in the modeling and reliability eval-uation of multi-state k out of n systems and its applications in engineering. Chap-ter 3 by Zhang, Xie, and Tang discusses a method for the parameter estimation ofWeibull distribution when there is no censoring using weighted least squares estima-

tion. They also present a simple approximation formula to calculate the weights fora small sample of size. Chapter 4 by Nakagawa and Mizutani discusses several char-acteristics of periodic cumulative damage models where the total damage is additive.The derivations of obtaining the optimum replacement policies along with numeri-cal examples are also discussed. Chapter 5 by Filus and Filus presents an overviewand the development concepts of stochastic reliability modeling approaches. Someanalytical description and application of stochastic dependences such as condition-ing method and transformations method are also discussed. Chapter 6 by Liu andMazzuchi discusses a comprehensive literature review on the various burn-in as-pects respect to cost functions. The authors also discuss various cost optimizationmodels and their warranty policies considering the concept of “per-item-output”.
Part II of the book contains five papers, and focuses on Reliability Engineeringin Design.
Chapter 7 by Elsayed and Zhang presents a predictive maintenance model ad-dressing multiple imperfect maintenance actions and optimization procedures todetermine the optimum system maintenance threshold level that achieves the max-imum system availability. Chapter 8 by Lu and Wang presents a method to esti-mate the reliability and its confidence limits for the Weibull distribution, when thereare only few or no failure data available. The Monte Carlo simulation techniquewith only three failure samples was also discussed to obtain the estimates of a two-parameter Weibull distribution. Chapter 9 by Xie and Wang presents an extendedstress-strength interference analysis method to calculate the fatigue reliability un-der constant cyclic load with uncertainty in stress amplitude. For a specified cyclicload amplitude distribution, fatigue reliability can be calculated using the statisti-cal average of the probabilities. Applications of the methods are also discussed toshow the effect of load uncertainty on reliability analysis. Chapter 10 by Fukuda,Tokuno, and Yamada presents a method to evaluate the performance of the softwaresystems considering real-time properties including time-dependent debugging ac-tivities using Markov process. Chapter 11 by Xie, Wang, Hao and Zhang providesa general review of the load-component strength interference relationship and thenpresents a time-dependent strength function to estimate the failure probability ofseries pipeline systems under randomly multiple load actions.
Part III of the book contains five papers, focuses on Software Reliability andTesting.
Chapter 12 by Folleco, Khoshgoftaar and Van Hulse discusses the impact of noisebased on the incomplete measurement data on the evaluation of software quality im-putation techniques including Bayesian multiple imputation, nearest neighbor impu-tation, decision tree imputation, and regression imputation. Chapter 13 by Kimurapresents a linearized growth curve model and its parameter estimation using themethod of two-parameter numerical differentiation. Chapter 14 by Hwang and Phamdiscusses a generalized time-delay software reliability model addressing the time re-quired to identify and prioritize the detected faults before removing them optimalpolicies using the method of steps. Numerical examples based on software failuredata are presented to illustrate the use of the proposed model when it is applied inpractice. Chapter 15 by Lipton and Gokhale presents architecture-based software
