From the editor.
June 22, 2002... The lead paper in this issue is a Feature Article by Michael Fu on a topic that's long been near and dear to me personally: methods to seek a combination of input parameters to a simulation model that optimize some output performance measure....

Optimization for simulation: Theory vs. Practice. (Feature Article).
June 22, 2002... Probably one of the most successful interfaces between operations research and computer science has been the development of discrete-event simulation software. The recent integration of optimization techniques into simulation practice,...

Simulation optimization: integrating research and practice. (Commentary).
June 22, 2002... The feature article by Fu (2002) identifies several areas within the field of simulation optimization that need further attention, including the development of good stopping criteria, providing improved measures of goodness for the estimated...

Additional perspectives on simulation for optimization. (Commentary).
June 22, 2002... Professor Fu has provided an excellent survey of the state-of-the-art in the area of simulation for optimization. His discussion offers insights into topics ranging from the evolution of commercial simulation software to future directions for...

Simulation Optimization is Evolving. (Commentary).
June 22, 2002... Michael Fu's paper comparing the theory and practice of simulation optimization implies that there is disconnect between academic research and commercial software. This author agrees wholeheartedly with this premise. The disconnect exists for...

Simulation optimization in the future: evolution or revolution? (Rejoinder).
June 22, 2002... I thank each of the commentators for their additional insights and perspectives on simulation optimization. In this rejoinder, I will attempt to briefly highlight or respond to a few of the points in the commentaries. First, all three of...

A hybrid GRASP with perturbations for the Steiner problem in graphs.
June 22, 2002... We propose and describe a hybrid GRASP with weight perturbations and adaptive path-relinking heuristic (HGP + PR) for the Steiner problem in graphs. In this multi-start approach, the greedy randomized construction phase of a GRASP is replaced...

Capacitated network design with uncertain demand.
June 22, 2002... We consider a capacity-expansion problem arising in the design of telecommunication networks. The problem is to install capacity on links of the network so as to meet customer demand while minimizing total costs incurred. When studying this and...

Symbolic computation of moments in priority queues.
June 22, 2002... Analytical tools such as Laplace-Stieltjes transforms and z-transforms are commonly used to characterize queueing-theoretic quantities such as busy-period, waiting-time, and queue-size distributions. Many of these transforms, particularly in...

An evolutionary approach to group decision making.
June 22, 2002... We propose modeling Group Support System (GSS) search tasks with Genetic Algorithms. Using explicit mathematical models for Genetic Algorithms (GAs), we show how to estimate the underlying GA parameters from an observed GSS solution path. Once...
