Journal Reliability: theory and applications No. 4 (Vol. 1)

Paper - 11 p In this paper the reliability is presented as an important feature for use in mission-critical distributed applications. Certain aspects of distributed systems make the requested level of reliability more difficult. An obvious benefit of distributed systems is that they serve the global business and social environment in which we live and work. Another benefit is that they can improve the quality of services, in terms of reliability,...

Article 12 pp,Polish Naval University The semi-Markov reliability model of the cold standby system with renewal is presented in the paper. The model is some modification of the model that was considered by Barlow & Proshan (1965), Brodi & Pogosian (1978). To describe the reliability evolution of the system, we construct a semi-Markov process by defining the states and the renewal kernel of that one. In our model the time to failure of the...

Paper - 16 pp System reliability is considered as an important performance index. Performance of engineering systems can be assessed by various techniques. The traditional analytical approach consists of developing a mathematical model that represents the system and to evaluate its reliability indices. There have been attempts in the literature to derive more realistic approaches for the reliability analysis of systems, for example, based on simu...

ISBN: 0824720008, 0849392470 Tools to Proactively Predict Failure The prediction of failures involves uncertainty, and problems associated with failures are inherently probabilistic. Their solution requires optimal tools to analyze strength of evidence and understand failure events and processes to gauge confidence in a design’s reliability.

1991 - 107 p This report presents the results of the first phase of the ongoing EG&G Idaho, Inc. , Software Reliability Research Program. The program is studying the existing software reliability mc:lels and proposes a state-of-the-art software reliability model that is relevant to the nuclear reactor control environment. This report consists of three parts: (1) summaries of the literature review of existing software reliability and fault tol...

Paper - 12 p This paper reviews recent developments in Bayesian software reliability modeling. In so doing, emphasis is given to two models which can incorporate the case of reliability deterioration due to potential introduction of new bugs to the software during the development phase. Since the introduction of bugs is an unobservable process, latent variables are introduced to incorporate this characteristic into the models. The two models are...

Paper - 21 p Prevalent black-box based approaches to software reliability modeling are inappropriate for the reliability assessment of modern component-based systems. The existing Markovian and semi-Markovian methods to predict the reliability and performance of such heterogeneous systems, suffer from several limitations: they are subject to an intractably large state-space for more involved scenarios, and they cannot take into account the influe...

Article 20 pp-Vlad Stefan Barbu, Nikolaos Limnios, November 19, 2006 This article presents the reliability of discrete-time semi-Markov systems. After some basic definitions and notation, we obtain explicit forms for reliability indicators. We propose nonparametric estimators for reliability, availability, failure rate, mean hitting times and we study their asymptotic properties. Finaly, we give a three state example with detailled calculus and n...
