摘要:

AbstractAn approximation for analyzing transient and nonstationary two‐priority non‐preemptive queueing systems is presented. This system has a three‐dimensional state space, and through use of state‐space partitioning in conjunction with use of conditional surrogate distributions with constant parameters an approximation is designed. Regardless of system capacityK, the approximation requires the numerical solution of only ten differential equations, compared to theK2+K+1 Kolmogorov‐forward equations required for the classic solution. Time‐dependent approximations of the mean number of entities of type i and of the probability of a type‐i entity being in service are obtained. Empirical test results over a wide range of systems indicate the approximation is q

摘要:

AbstractObservations from inspection by a “test” method and a standard method are combined to provide estimators of population proportion, and of probabilities of misclassification for the test method. Results of Hochberg and Tenenbein [3] and of Albers and Veldman [1]are extended to the case where the standard method is not perfect, but its misclassification probabilities have known values. Both moment and maximum‐likelihood estimators are considered and some asymptotic properties of the resulting estimators are com
