    Two broad categories of human error occur during software development: (1) development errors made during requirements analysis, design, and coding activities; (2) debugging errors made during attempts to remove faults identified during software inspections and dynamic testing. This paper describes a stochastic model that relates the software failure intensity function to development and debugging... View full abstract»

  • Availability and reliability of system with dependent components and time-varying failure and repair rates

    System reliability depends not only on the reliabilities of components in the system but also on their interactions. Generally, in a system, not only s-independent failures but also s-dependent failures among components can occur; thus there are many studies where the s-dependencies among components are taken into account in system reliability and availability analysis, but in which the failure an...

  • Defining mean time-to-failure in a particular failure-state for multi-failure-state systems

    In multi-failure-state systems which have both dangerous (critical) and safe (noncritical) failure states, it is both meaningful and important to be able to measure the MTTF in a particular failure state separately from MTTF in general. MTTFD (fail dangerous) and MTTFS (fail safe) are defined, emphasizing the engineering context of the problem. Methods are developed for compu... View full abstract»

    This paper presents a methodology and an example of risk assessment of functional-requirement specifications for complex real-time software systems. A heuristic risk-assessment technique based on CPN (colored Petri-net) models is presented. This technique is used to classify software functional-requirement specification components according to their relative importance in terms of such factors as ... View full abstract»

  • A discretizing approach for evaluating reliability of complex systems under stress-strength model

    This paper introduces a new discretizing approach for evaluating reliability of any complex system where analytic methods fail to offer a closed-form solution. Numerical analyses on 4 important engineering items have been used to examine the closeness between the proposed reliability estimators and the simulated values. A comparative study between the discretizing approach of English et al. (1996)... View full abstract»

  • Reliability of conformance tests

    Conformance testing is considered from a statistical point of view. An s-confidence interval is found for the reliability that an implementation of a software package complies with specifications of a standard. Determination of whether it complies depends on a conformance test, which is written directly from the standard. Although the conformance test is written directly from the standard it does ...

  • Effect of code coverage on software reliability measurement

    Existing software reliability-growth models often over-estimate the reliability of a given program. Empirical studies suggest that the over-estimations exist because the models do not account for the nature of the testing. Every testing technique has a limit to its ability to reveal faults in a given system. Thus, as testing continues in its region of saturation, no more faults are discovered and ...

  • Estimating transition-probabilities in a dynamic graphic model with unobservable variables

    This paper emphasizes the utility of graphic models in describing partially observed dynamic systems, and establishes a method for estimating the parameters of the model. A dynamic graphic model with an associated graphic structure, which consists of a sequence of chain graphs with two consecutive graphs in the sequence connected by directed links, is described. The chain graphs describe relations... View full abstract»

  • Some properties of a classification system for multivariate life distributions

    A good classification system for multivariate life distributions can play a major role in system analysis during the early stage of product design. The problem of multivariate classification has drawn the attention of the researchers, and various classes are now available in the literature. D. Roy (1994) proposed a unified classification system for the multivariate life laws. It not only retains t... View full abstract»

    This paper suggests a new model for reliability demonstration of safety-critical systems, based on the TRW Software Reliability Theory. The paper describes the model, the test equipment required, and test strategies based on the various constraints occurring during software development.

    One of the basic problems of dependability modeling is the adequate abstraction of real-world technological problems to the principle terms of reliability/safety scenarios. This concerns primarily the definition of components and of faults on different system levels. Given these terms the rest of any modeling needs basic logical operations, mostly AND and OR, and delays, and often some counting (o... View full abstract»

    This paper is adapted from the author's speech at the Annual Reliability and Maintainability Symposium, January, 2001. The author discusses decision-making, hazards, technological upsets, and the social contexts within which reliability decisions are made. Suggestions are given on the areas where those in reliability and maintainability can help in establishing social policy for products and proce... View full abstract»

    Our new method uses order statistics to judge the fit of a distribution to data. A test-statistic based on quantiles of order-statistics compares favorably with the Kolmogorov-Smirnov (K-S) and Anderson-Darling (A-D) test statistics. The performance of this new goodness-of-fit test statistic is examined with simulation experiments. For certain hypothesis tests, the test statistic is more powerful ... View full abstract»
