This short communication considers a tandem queue fed by Lévy input. The main result concerns expressions for the Laplace transform of the transient workload in the downstream queue, under the condition that the system starts off empty. This expression greatly simplifies if the driving Lévy...

Given the trend of increasing business globalization, management teams of multinational companies have taken steps to better understand consumers, local business partners, and local governments. Local queueing preferences present managers with additional challenges and opportunities in...

Kriging (Gaussian process, spatial correlation) metamodels approximate the Input/Output (I/O) functions implied by the underlying simulation models; such metamodels serve sensitivity analysis and optimization, especially for computationally expensive simulations. In practice, simulation analysts...

This is a preliminary draft of an Invited Symposium paper for the World Congress of the Econometric Society to be held in Seattle in August 2000. We discuss the strong connections between auction theory and 'standard' economic theory, and argue that auction-theoretic tools and intuitions can...

The paper models the practice of charging bribes for faster delivery of essential services in third world countries. It then examines the possibility of curbing corruption by supervision, and secondly, by introducing competition among delivery agents. It is argued that a supervisory solution...

Demonstrates the application of spreadsheets in simulating queuing systems with arrivals from a finite population. The problem is referred to as the machine repair problem where the members of the queue are machines that are breaking down and the servers are the technicians repairing the broken...

We develop a methodology for studying ''large deviations type'' questions. Our approach does not require that the large deviations principle holds, and is thus applicable to a larg class of systems. We study a system of queues with exponential servers, which share an arrival stream. Arrivals are...

Since consumers feel that time is becoming an increasingly scarcer resource, service organizations are also becoming increasingly sensitive to the economical and psychological costs which they impose on their clients in waiting lines. Reports a study aimed at examining the relations between two...

Suggests that while businesses have made great efforts to reduce the length of time customers wait for service, little attention has been paid to the actual experience of waiting. Argues that the final service encounter is crucial for reinforcing customers′ performance expectations. Suggests...
