    An exponential reliability-growth model, which incorporates step changes in the failure intensity, is proposed as an alternative to other reliability-growth models commonly used to analyze the failure process of repairable equipment in a development program. A multicopy testing-modification scenario is used in which several s-identical copies are put on test, and design modifications are introduce... View full abstract»

    A model is developed to determine the variance of system reliability estimates and to estimate confidence intervals for series-parallel systems with arbitrarily repeated components. For these systems, different copies of the same component-type are used several or many times within the system, but only a single reliability estimate is available for each distinct component-type. The single estimate... View full abstract»

  • A neural approach to topological optimization of communication networks, with reliability constraints

    Consider network topological optimization under a reliability constraint. The objective is to find the topological layout of links, at minimal cost, under the constraint: all-terminal network reliability is not less than a given level of system reliability. The all-terminal reliability is Pr{every pair of nodes in the network can communicate with each other}. This paper presents a new approach bas... View full abstract»

  • Incorporating common-cause failures into nonrepairable multistate series-parallel system analysis

    This paper adapts the universal generating function method of multistate system reliability analysis to incorporate common-cause failures (CCF). An implicit 2-stage approach is used. In stage #1, a polynomial representation of system-output performance distribution is obtained without considering system elements which are subject to CCF. In stage #2, the contribution of CCF is correctly included b... View full abstract»

  • A distribution-free lower bound for availability of quantile-based inspection schemes

    This paper develops a lower bound for the availability of quantile-based inspection schemes when device lifetimes are assumed to have an increasing failure rate. The lower bound is useful in designing inspection schemes when lifetime distributions are not explicitly known, but must be estimated from limited failure data View full abstract»

    The statistical (black box) remaining lifetime of some simple coherent systems is stochastically compared with the remaining lifetime based on the information at hand. Parallel and cold standby systems of s-identical components with exponentially distributed lifetimes are considered. Information-based remaining lifetime is defined via the number of the nonfailed components at the moment of observa... View full abstract»

    Safety-critical systems require an assessment activity to verify that they are able to perform their functions in specified use environments. This activity benefits from evaluation methods that consider these systems as a whole and not as the simple sum of their parts. Indeed, analysis of accidents involving such systems has shown that they are rarely due to the simple failure of one of their comp... View full abstract»

    Since their introduction in the reliability field, binary decision diagrams have proved to be the most efficient tool to assess Boolean models such as fault trees. Their success increases the need of sound mathematical foundations for the notions that are involved in reliability and dependability studies. This paper clarifies the mathematical status of the notion of minimal cutsets which have a ce... View full abstract»

    Estimating warranty costs during the life cycle of a product is important to the manufacturer, who has to plan for creating a fund for warranty reserves. Replacement or repair costs associated with product-failure within the warranty period are drawn from this fund. This paper considers a policy where warranty is not renewed on product failure within the warranty period but the product is minimall... View full abstract»

    The purpose of this paper is to describe an approach to real-time reliability prediction, applicable to an individual product unit, operating under dynamic conditions. The concept of conditional reliability estimation is extended to real-time applications using time-series analysis techniques to bridge the gap between physical measurement and reliability prediction. The model is based on empirical... View full abstract»

    The cumulative hazard function H(n) should accumulate to infinity over the distribution support, because the survivor function is Sf(n)=exp(-H(n)). The widely used approximation for the cumulative hazard function, H(n)≈Σk=1nh(k), for a small value of the hazard function, h(k), can be useful and reasonably accurate for computing the survivor function. For the continuo... View full abstract»

    This paper describes a maintenance scheduling for pump systems in thermal power stations in order to reduce the maintenance cost during the whole period of operation, while keeping the current reliability level of the pump system. The dimensional reduction method is used to solve the problem in which a few available data are used together with other factors relating to the failures of pumps. The p... View full abstract»

  • An efficient method for evaluating network-reliability with variable link-capacities

    An efficient method is proposed to evaluate the network reliability with variable link capacities when the simple paths of the network are known. Most of the evaluation techniques proposed in the literature so far are based on enumerating the k-composite paths, each of which is a union of k simple paths. Although some of those methods lead to correct results, the redundancy is still quite large an... View full abstract»
