    A method is presented for apportioning reliability growth to the subsystems that make up a system in order to achieve the required reliability at least cost. Reliability growth apportionment is handled as an s-expected cost minimization problem subject to the constraint of meeting a system reliability requirement. The problem is formulated in terms of Duane's reliability growth model, and is solve... View full abstract»

    A 3-state Markov-chain model has been developed to analyze the relationship between the failure rate and the technician visitation rate for remote electronic equipment facilities. The major assumption of the model is that a facility, prior to failure, will give an observable indication that it is about to fail. In order for the model to predict the failure rate for a change in technician visitatio... View full abstract»

  • A Reduction Technique for Obtaining a Simplified Reliability Expression

    Publication Year: 1977, Page(s):248 - 249
    Cited by:  Papers (13)

    A reduction technique is described for obtaining a simplified reliability expression (probability of success) when applied to the canonical form of minterms (having independent variables) such as those generated from a truth table format. The resulting terms are always mutually exclusive, which allows simple, direct transformation to a probability expression. View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (369 KB)

    A substitutionary decomposition method for computing the reliability of a redundant system S given by a Boolean expression is proposed, System S is decomposed into two subsystems S(x) and S(x) according to up-and down-states of its keystone variable x. This is repeated until all terms become s-independent in each decomposed subsystem. A criterion for choosing the keystone variable and a property w... View full abstract»

  • Queuing Models for Estimating Aircraft Fleet Availability

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (575 KB)

    The availability of a small fleet of aircraft in a flying-base, repair-depot combination is modeled and studied. First, a deterministic flow model relates parameters of interest and represents the state-of-the art in the planning of such systems. Second, a cyclic queue model shows the effect of the principal uncertainties in operation and repair and shows the consequent decrease in the availabilit... View full abstract»

    Distribution-free methods are evolved for 4 models of evaluating time-to-failure. Two decision procedures for choosing the better of two equipments are given in models I & II. Decision procedures for whether two equipments have the same availability or reliability are given in models III & IV; in these models, it is assumed that the mission time is a r.v. in the interval (0, T0). The method of mod... View full abstract»

    An approach to calculate the stationary state probabilities and in particular the stationary point availability of redundant systems with repair is presented. The approach is based on the theory of random marked point processes. The tractibility of the results is demonstrated by an example. View full abstract»

    Maximum likelihood estimators for the parameters of a multivariate exponential Cdf are easily obtained from partial information about a random sample, censored or not. The partial information consists of the minimum from each multivariate observation and the counts of how often each r.v. was equal to the minimum in an observation. The censoring might cause only the smallest r out of n minima to be... View full abstract»

    The design of modules to have some redundant functions in order to minimize module production cost is analysed. Upon production modules with failed functions are either discarded or repaired. If some functions have 2 elements in parallel, the production cost of a module can be minimized if modules are discarded or repaired, depending on the number of redundant functions, number of functions per mo...

    A class of redundant cascaded chains with i.i.d. modules is considered in which recovery from a failure takes place by replacing the faulty module by a spare module. The complexity of the reconfiguration process depends upon the location of spare modules in the cascade. This paper deals with the question of optimally placing the spare modules in order to minimize the s-expected recovery time (down... View full abstract»
