We present a general framework for applying simulation to optimize the behavior of discrete event systems. Our approach … decision parameters. We then show how simulation and the likelihood ratio method can be used to evaluate the performance …

Cross-ruff coupons are obtained at the time of purchase of a carrier brand and may be redeemed at a later date on a target brand. These coupons therefore have the ability to link consumer purchases across different brands as well as shopping trips. We model the effects of cross-ruff coupons on...

In this paper we investigate importance sampling techniques for the simulation of Markovian systems with highly … reliable components. The need for simulation arises because the state space of such systems is typically huge, making numerical … computation inefficient. Naive simulation is inefficient due to the rarity of the system failure events. Failure biasing is a …

This paper presents an inventory-control model which includes a Markovian model of the supply system. As that system evolves over time, so do the replenishment leadtimes. The optimal policy has the same structure as in standard models, but its parameters change dynamically to reflect current...

We develop a new model for studying the phenomenon of congestion in a transient environment, focusing on the problem of aircraft landings at a busy "hub" airport. Our model is based on a Markov/semi-Markov treatment of changes in the weather, the principal source of uncertainty governing service...

We define a high volume factory to be a connected network of workstations, at which assigned workers process work-in-progress that flows at high rates through the workstations. A high rate usually implies that each worker processes many pieces per hour, enough so that work can be described as a...
