    The probabilistic safety assessed to N fuel rods assembled in one core of a nuclear reactor is commonly modelled by the sum of N independent Bernoulli random variables, i.e. 1 or 0, with individual safety probability pi that the i-th rod shows no failure during one cycle, coded by 1. The requirement set by the German Reaktor-Sicherheitskommission (Reactor Safety Commission) demands that... View full abstract»

    Dependability evaluation is a fundamental step in distributed control system design. However, the current dependability evaluation methods are not appropriate due to the level of complexity of such systems. Given the ineffectiveness of these methods, we propose the Safe-SADT formalism for dependability evaluation (SADT stands for Structured Analysis and Design Techniques). This formalism allows th...

    Several recent studies have reported & examined the phenomenon that long-running software systems show an increasing failure rate and/or a progressive degradation of their performance. Causes of this phenomenon, which has been referred to as "software aging", are the accumulation of internal error conditions, and the depletion of operating system resources. A proactive technique called "softwa... View full abstract»

    This paper proposes a novel heterogeneous software architecture GFTSA (Generic Fault Tolerant Software Architecture) which can guide the development of safety critical distributed systems. GFTSA incorporates an idealized fault tolerant component concept, and coordinated error recovery mechanism in the early system design phase. It can be reused in the high level model design of specific safety cri... View full abstract»

    Over the past 30 years, many software reliability growth models (SRGM) have been proposed. Often, it is assumed that detected faults are immediately corrected when mathematical models are developed. This assumption may not be realistic in practice because the time to remove a detected fault depends on the complexity of the fault, the skill and experience of personnel, the size of debugging team, t...

    This paper presents an analytical method for evaluating the reliability improvement for any size of multi-computer system based on Software-Implemented Fault-Tolerance (SIFT). The method is based on the equivalent failure rate Gamma, the single node failure rate lambda, the number of nodes in the system, N, the repair rate mu, the fault coverage factor c, the reconfiguration rate delta, and the pe...

    This paper presents a new methodology for predicting software reliability in the field environment. Our work differs from some existing models that assume a constant failure detection rate for software testing and field operation environments, as this new methodology considers the random environmental effects on software reliability. Assuming that all the random effects of the field environments c... View full abstract»

  • Bounds on MTBF of Systems Subjected to Periodic Maintenance

    Mean time between failures (MTBF) is a common reliability measure used to assess the failure behavior of repairable systems. In order to increase MTBF, in most systems, it is a common practice to perform preventive maintenance activities at periodic intervals. In this paper: We first discuss the validity of a commonly used equation for computing MTBF of systems subjected to periodic maintenance.) ... View full abstract»

    The Binrbaum-Saunders (B-S) distribution was derived in 1969 as a lifetime model for a specimen subjected to cyclic patterns of stresses and strains, and the ultimate failure of the specimen is assumed to be due to the growth of a dominant crack in the material. The derivation of this model will be revisited, and because the assumption of independence of crack extensions from cycle to cycle can be... View full abstract»

  • Customer-Rush Near Warranty Expiration Limit, and Nonparametric Hazard Rate Estimation From Known Mileage Accumulation Rates

    Time or mileage data obtained from warranty claims are generally more accurate for hard failures than for soft failures. For soft failures, automobile users sometimes delay reporting the warranty claim until the warranty coverage is about to expire. This results in an unusually high number of warranty claims near the end of warranty coverage. Because such a phenomenon of customer-rush near the war... View full abstract»

    Planned replacement policies are used to reduce the incidence of system failures, or to return a failed system to work. New better than used aging classes are commonly used in reliability theory to model situations in which the lifetime of a new unit is "better" than the lifetime of a used one. The purpose of this paper is to establish comparisons of expected failure times of an age (block) replac... View full abstract»

    We study the optimal configuration of p-cycles in survivable wavelength division multiplexing (WDM) optical mesh networks with sparse-partial wavelength conversion while 100% restorability is guaranteed against any single failures. We formulate the problem as two integer linear programs (Optimization Models I, and II) which have the same constraints, but different objective functions. p-cycles and... View full abstract»

    The paper considers grid computing systems with star architectures in which the resource management system (RMS) divides service tasks into subtasks, and sends the subtasks to different specialized resources for execution. To provide the desired level of service reliability, the RMS can assign the same subtasks to several independent resources for parallel execution. Some subtasks cannot be execut...

    The k-out-of-n structure is a very popular type of redundancy in fault-tolerant systems. It has been applied in industrial, and military systems. In this paper, we investigate the general residual life (GRL) of a (n-k+1)-out-of-n system with i.i.d. components, given that the total number of the failures of components is less than l-1(1lesl<klesn) at time tges0. It is shown that the GRL is decre... View full abstract»

    We review the principal progress of shock models during the last three decades. Our new model, the delta-shock model, and its latest developments are also introduced. Furthermore, for adapting shock models to a wider reliability field, we put forward a generalized framework for studying shock models, based on cluster point processes with cluster marks. In addition, we provide a noteworthy case und... View full abstract»

    A new heuristic is proposed and tested for system reliability optimization. The multiple weighted objective heuristic is based on a transformation of the problem into a multiple objective optimization problem, and then ultimately, transformation into a different single objective problem. The multiple objectives are to simultaneously maximize the reliability of each individual subsystem. This is a ... View full abstract»

    Effects of parameter estimation are examined for the well-known p-chart for the fraction nonconforming based on attributes (binary) data. The exact run-length distribution of the chart is obtained for Phase II applications, when the fraction of nonconforming items, p, is unknown, by conditioning on the observed number of nonconformities in a set of reference data (from Phase I) used to estimate p....
