    This paper presents a degradation modeling framework for computing condition-based residual life distributions of partially degraded systems and/or components functioning under time-varying environmental and/or operational conditions. Our approach is to mathematically model degradation-based signals from a population of components using stochastic models that combine three main sources of informat... View full abstract»

    Spare capacity allocation serves as one of the most critical tasks in dynamic GMPLS networks to meet the stringent network availability constraint stipulated in the SLA of each connection. In this paper, an availability-aware spare capacity reconfiguration scheme based on shared backup path protection (SBPP) is proposed, aiming to guarantee the E2E availability of each LSP. We first provide an E2E... View full abstract»

  • Hierarchical Variance Decomposition of System Reliability Estimates With Duplicated Components

    A hierarchical decomposition procedure is proposed to determine the variance of the reliability estimate for complex systems with duplicated components. For these systems, multiple copies of the same component type are used within the system, but only a single reliability estimate is available for each distinct component type. The variance of the reliability estimate is magnified at the system-lev... View full abstract»

    We consider a coherent structure consisting of n components having the property that if it is known that at most r components (r < n) have failed, the system is still operating with probability 1. Some examples of the systems having this property are (n - k + 1)-out-of- n, some parallel-series, and some series-parallel structures. Depending on th... View full abstract»

  • A Fast Algorithm for Searching All Multi-State Minimal Cuts

    Evaluating network reliability is an important topic in planning, designing, and control of systems. Many real-world systems are limited-flow (multi-state) networks composed of multi-state components, and their reliabilities can be computed in terms of minimal cut (MC) vectors to level d (named d-MC). A straightforward exact algorithm is presented here. The idea is to find all ... View full abstract»

    Compared with a binary system model, a multi-state system model provides a more flexible tool for representing engineering systems in real life. In conventional multi-state theory, it is assumed that the exact probability and performance level of each component state are given. However, it may be difficult to obtain sufficient data to estimate the precise values of these probabilities and performa... View full abstract»

    Multistate systems (MSS) are systems in which both the systems, and/or their components may exhibit multiple performance levels or states. MSS can model complex behaviors such as shared loads, performance degradation, imperfect fault coverage, standby redundancy, and limited repair resources. The non-binary state property of MSS, and their components makes the analysis of MSS challenging. In this ... View full abstract»

    We were curious about how well various reliability and testing models would compare with respect to prediction accuracy and testing effectiveness. Therefore, we conducted several experiments to evaluate these properties for the following models: fault tree analysis, geometric and binomial statistical models; and reliability growth models: Yamada S Shape Model, Schneidewind Single Parameter Model, ...

  • Inference for a Simple Step-Stress Model With Type-II Censoring, and Weibull Distributed Lifetimes

    The simple step-stress model under type-II censoring based on Weibull lifetimes, which provides a more flexible model than the exponential model, is considered in this paper. For this model, the maximum likelihood estimates (MLE) of its parameters, as well as the corresponding observed Fisher information matrix, are derived. The likelihood equations do not lead to closed-form expressions for the M... View full abstract»

    Consecutive successes total failures (CSTF) is a well known start-up demonstration test procedure in which a unit under test is accepted when successive start-up attempts produce a specified number of consecutive successes before a specified number of failures; otherwise the unit is rejected, and in both cases testing (the experiment) is terminated. The CSTF procedure is studied here assuming that... View full abstract»

  • A New Method for Goodness-of-Fit Testing Based on Type-II Right Censored Samples

    We present a simple method for testing goodness-of-fit based on type-II right censored samples. Applying the property of order statistics due to Malmquist, we can transform any conventional type-II right censored sample of size r out of n from a uniform distribution to a complete sample of size r from a uniform distribution. This result is used to develop the proposed goodness... View full abstract»

    The choice of an appropriate life test sampling plan is a crucial decision problem because a good plan not only can help producers save testing time, and reduce testing cost; but it also can positively affect the image of the product, and thus attract more consumers to buy it. This study developed a decision model in determining the optimal life test sampling plan with an aim of cost minimization ... View full abstract»

    This paper proposes a generalized formulation for multilevel redundancy allocation problems that can handle redundancies for each unit in a hierarchical reliability system, with structures containing multiple layers of subsystems and components. Multilevel redundancy allocation is an especially powerful approach for improving the system reliability of such hierarchical configurations, and system o... View full abstract»

    The present paper examines the effect of safe failure fraction (SFF) constraints on hazardous-event rates, and discusses the validity of the SFF constraints in IEC 61508. First, the safe states are categorized into three types of states, and overall systems involving safety-related systems are classified into six types of systems based on the safe-state categorization, and the completeness of trip...
