An Introduction to Reliability and Quality Engineering
TLDR
In this paper, the authors defined the principles of quality and reliability in manufacturing and maintenance of a product, including the meaning of quality product specification using continuous performance characteristics, and the reliability of the product.Abstract:
Part 1 Principles of quality and reliability: the quality of a product the meaning of quality product specification using continuous performance characteristics statistical analysis of continuous performance characteristics comparison of performance statistics with product specification the reliability of a product the meaning of reliability practical reliability definitions instantaneous failure rate and its relation to reliability typical forms of hazard rate function rules for combining probabilities. Part 2 Reliability of systems: series systems parallel systems general series-parallel system majority voting systems standby systems common mode failures availability of systems. Part 3 Failure rate data and models: failure rate data failures influencing failure rate failure rate models calculation of equipment failure rate from component failure rate data software reliability human reliability. Part 4 Quality and reliability in manufacture: the achievement of quality economics of quality and reliability design for quality and reliability quality and reliability in production testing of the finished product. Part 5: Reliability in maintenance: reliability and the total cost of ownership breakdown maintenance preventive maintenance on-condition maintenance. Part 6 Protective systems for hazardous processes: introduction the hazardous process target hazard rate for the protective system choice of trip initiating parameters design of the protective system hazard analysis of process and protective system.read more

Wavelet packet based damage identification of beam structures
TL;DR: In this article, a damage detection index called wavelet packet energy rate index (WPERI) was proposed for the damage detection of beam structures, where the measured dynamic signals are decomposed into the wavelet packets components and the WPERI is computed to indicate the structural damage.

Systemic approach for the maintenance of complex structural systems
TL;DR: In this article, a general framework for the development and maintenance of complex structural systems is presented, with the overall design phase defined with the aid of the performance-based design philosophy, emphasizing the concepts of dependability and enlightening the role of structural identification.

Joint optimal inspection and inventory for a k-out-of-n system
TL;DR: A model, which optimizes jointly the inspection frequency and the inventory level for a k-out-of-n system with repairable components whose failures are hidden and follows a non-homogeneous Poisson process is developed.

Soft Computing Based Multilevel Strategy for Bridge Integrity Monitoring
S. Arangio,Franco Bontempi +1 more
TL;DR: Bayesian neural networks model is chosen and successfully improved by applying the Bayesian inference at four hierarchical levels: for training, optimization of the regularization terms, data‐based model selection, and evaluation of the relative importance of different inputs.

Reliability based approach for structural design and assessment: performance criteria and indicators in current European codes and guidelines
TL;DR: In this paper, the reliability based approach for design and assessment of civil engineering systems is discussed, in particular the performance criteria and indicators given in current structural codes are discussed, and the concept of dependability is introduced.
