    This study shows that sockets can be reliable enough in a relatively benign environment for the short-term. Criteria for failure-free performance include 1) operation in a controlled, non-vibration environment, 2) gold-plated, machined sockets, 3) either gold or tin-plated IC leads. Accelerated testing is required to estimate long-term reliability. Numerous federal and commercial systems use socke... View full abstract»

  • A Fault Tree Approach to Quality Control by Variables

    Based on the analogy between the events ``component failed'' (in reliability) and ``measurement out of tolerances'' (in quality control) acceptance sampling by variables is investigated when using the measurements made at several check-points for each device to be tested. The joint use of the fault-tree approach (especially in terms of min-cuts and min-paths) and of finite-sample hypothesis testin... View full abstract»

  • An Efficient Bottom-up Algorithm for Enumerating Minimal Cut Sets of Fault Trees

    The paper improves the conventional bottom-up algorithm for enumerating minimal cut sets of fault tree. It is proved that, when the logical product of two reduced sum-of-product forms is expanded by the distribution rule, one need only check if each resulting term is absorbed by some terms of two original sum-of-product forms. The algorithm for executing this process is presented and illustrated b... View full abstract»

    The method of synthesis for calculating the reliability of a complex network was developed by Woodcock. However, he experienced some difficulty in properly incorporating s-dependency, and this often necessitated considerable manipulation of the network beforehand. This difficulty is overcome in the present method by working with algebraic expressions involving component failure probabilities, and ... View full abstract»

  • Equivalence of a Nonoriented Line and a Pair of Oriented Lines in a Network

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (539 KB)

    Equivalence of a nonoriented line and a pair of oriented lines (in the reliability-sene) is examined for four types of networks. Type I has one input node and one output node; type II has one input node and two or more output nodes; type II' has two or more input nodes and one input node; type III has two or more input nodes and two or more output nodes. For types I, II, II', every non-oriented li... View full abstract»

    This paper describes and analyses the Kumamoto, Tanaka, Inoue (KTI) Monte Carlo method for estimating the reliability R of an s-coherent system by bracketing it between deterministic lower and upper bounds, and then positioning R between the bounds as a weighted average of the structure functions of Monte Carlo generated k-vectors. The procedure is illustrated with both a 2-out-of-3 system and a l... View full abstract»

  • Inverting and Minimizing Boolean Functions, Minimal Paths and Minimal Cuts: Noncoherent System Analysis

    An efficient technique is presented for inverting the minimal paths of a reliability logic diagram or fault tree, and then minimizing to obtain the minimal cuts, or else inverting the minimal cuts for the minimal paths. The method is appropriate for both s-coherent and s-noncoherent systems; it can also obtain the minimized dual inverse of any Boolean function. Inversion is more complex with s-non...

    Stochastic processes within the general Poisson family, but distinguished by having rates which are changed by events, rather than by time, accurately describe the software error detection process. Several promising new models of this general type have been developed by the author and apply to hardware and software reliability problems, especially during the bum-in and wear-out phases. The growth ... View full abstract»

    A notation for defining events to a computer program is described. It has been used in weapon-effect simulation models. It is simple and can be efficiently processed by computer. Computer codes using the notation have been developed with small effort. View full abstract»

    This paper describes a reliability analysis of a system where its components take one of three states-good, degraded, or bad. For this 3-state system, the analogy of 2-state system is investigated. The calculation of system reliability can be reduced to that of the reliability of a corresponding 2-state system, provided that it is a generalized S-P system, with or without artificial, degraded comp...

    Usually, more than one independent (conflicting) criterion is important in determining the replacement age of a critical item for a maintained system. In this study, mathematical models have been developed for three such criteria: 1) minimum replacement cost-rate, 2) maximum availability, and 3) lower-bound on mission reliability. The solutions are obtained using four methods for multiple criteria... View full abstract»

    A modified block replacement policy is examined with the purpose of excluding the wastefulness caused by the property that almost new items might be sometimes replaced at planned replacement times under the ordinary block replacement policy. This modified policy can be stated as follows: 1) Operating items are replaced by new items at times kT (k = 1,2,...), 2) If operating items fail in [(k - 1)T... View full abstract»
