    A practical classification rule for a SQ (software quality) model considers the needs of the project to use a model to guide targeting software RE (reliability enhancement) efforts, such as extra reviews early in development. Such a rule is often more useful than alternative rules. This paper discusses several classification rules for SQ models, and recommends a generalized classification rule, wh... View full abstract»

    This paper presents three mathematical models for network design of cellular networks. The models reflect varying degrees of complexity. Model 1 is a 1-period fixed-link capacity model. Three heuristics are used for solving this problem. All the heuristics first use linear programming relaxations to yield the near-optimal integer solution, then use clever rounding-schemes to find the final solutio... View full abstract»

  • Bootstrap confidence regions for the expected ROCOF of a repairable system

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (112 KB)

    Bootstrap methods are presented for constructing s-confidence regions for the s-expected ROCOF (rate of occurrence of failures) of a repairable system. This is based on the work of Cowling, et al. (1996) for the intensity function of a NHPP (nonhomogeneous Poisson process). The method is applied to the operating times of unscheduled maintenance actions for a diesel engine of the USS Grampus given ... View full abstract»

  • Thermal stability of MISFET with low-temp molecular-beam epitaxy-grown GaAs and Al0.3Ga0.7As gate ins

    GaAs and Al0.3Ga0.7As epilayers grown at LT by MBE were used as insulators in the fabrication of MISFET devices. Parametric changes were used to evaluate the thermal stability of MISFET, to identify failure mechanisms and validate the reliability of these devices. The LT-Al0.3Ga0.7As MISFET showed superior thermal stability. The degradation in the perfor... View full abstract»

  • Fitting the Weibull log-linear model to accelerated life-test data

    Publication Year: 2000, Page(s):217 - 223

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (168 KB)

    The Weibull log-linear model is a widely-used accelerated life-test model in reliability engineering. The standard deviation of log(life), s, was often assumed to be a constant or stress-independent. However, theoretical and experimental research results suggest that, in many cases, s is stress-dependent. The data analysis via the MLE method must be performed numerically, because of the complexity... View full abstract»

    The 2-parameter family of probability distributions introduced by Birnbaum and Saunders characterizes the fatigue failure of materials subjected to cyclic stresses and strains. It is shown that the methods of accelerated life testing are applicable to the Birnbaum-Saunders distribution for analyzing accelerated lifetime data, and the (inverse) power law model is used due to its justification for d...

    This paper proposes an imperfect-repair model for repairable systems where two repair modes, perfect and minimal, occur in accordance with a Markov chain. It investigates the characteristics of the model and presents a statistical procedure for estimating the lifetime distribution of the system, based on consecutive inter-failure times. Under the Brown-Proschan imperfect repair model, the system i... View full abstract»

    TG (task graphs) are used to describe the execution of several tasks under some precedence constraints. Direct evaluation of TG provides an average completion time of the overall job, assuming no limits exist in the number of processing units and with no regard for allocation schemes. This paper presents a systematic approach for evaluating TG of jobs executed under predetermined allocation constr... View full abstract»

    This paper presents reliability sampling plans for the lognormal distribution based on progressively censored samples. In constructing these sampling plans, large-sample approximations to the best linear unbiased estimators of the location and scale parameters are used. For some selected progressive censoring schemes, reliability sampling plans are tabulated for pα and p... View full abstract»

    In repairable systems, the steady-state availability is one of the more important factors in specifications and choice of hardware. Some (not all) books, and some expensive courses on reliability, suggest that the steady-state availability of a series system is found by the product rule as for reliability. This is wrong. When a series system fails due to the failure of any one of its components, a... View full abstract»

    This paper is concerned with ETA (event-tree analysis) where the branch point event causes are defined using fault trees. Attention is on the nontrivial situation where there are dependencies amongst the branch point events. The dependencies are due to component-failures in more than one of the fault trees. In these situations the analysis methods based on traditional FTA (fault-tree analysis) are... View full abstract»

    A misunderstanding exists in the PRA (probabilistic risk assessment) field over what constitutes correlated data. This report clarifies the applications that fit the initial intent of the definition. In addition, even when used as intended, current theory appears to give an overly conservative answer. A more realistic answer, which is still conservative (e.g., overestimates the failure frequency o... View full abstract»
