摘要:

We consider a stochastic dynamic single product inventory model with finite horizon and allow the demand process to be dependent. Conditions are found for the optimally of a (zZ) strategy. In case of an independent demand process the results carry over to the optimality of an (sS) strategy.

摘要:

A dynamic inventory model with random demands is considered. Purchase costs and convex holding and shortage costs are assumed. The planning horizon is divided in intervals of the same length, and the cumulative stock on order is bounded by a constantRin every of these intervals. It is shown that a modification of an (SS) policy is optimal by these assumptions.

摘要:

Using a formula for the intensity measure of stationary marked point processes some of fundamental formulas of stereology are proved for a grain model with non-Poisson germ, process, for example that for mean volume fraction and mean surface area per unit area.

摘要:

This paper deals with the availability of 1-server 2-unit system with slow switch. The switch is taken up for maintenance after completingr(fixed number) switching operations. Explicit expression for the Laplace transform of the mean up-time of the system during (0t) is obtained. The steady-state availability to the system is discussed, xne case when the switch-over is instantaneous is also considered.

摘要:

This paper considers a 2-unit warm standby system. The failure time of the operating unit and the repair time of the failed unit are assumed to be independent random variables with general distribution functions. If one unit is in operation the repaired standby unit has a constant failure rate, There is only one repair facility for the 2 units. The number of repairs completed In a period and the total repair time are studied.

摘要:

A single server, limited capacity queueing system with Poisson arrivals and exponential service is studied. The joint probability distribution of the number of times the system reaches its capacity in time interval (0t] and the number of customers in the system at time i has been obtained. From, the joint probability, the probability that the system has reached its capacity m times in time interval (0t] has been determined and the expectation and variance have been found explicitly. A criterion for the system to be optimum is established and is illustrated numerically.
