چکیده

In most scheduling literature, constraints are seemingly generated in an ad-hoc manner using intuitive arguments. This could result in overlooking some constraints or including unnecessary constraints. Schruben (2000) has shown how the dynamics of some discrete event systems can be modeled as the solutions of optimization programs. In this paper, we use this idea to generate mathematical programming models systematically for scheduling resources in discrete event dynamic systems. Two examples are presented: a multiple server queue and a semiconductor manufacturing cluster tool. An interesting result was that the mathematical structure of the scheduling program generated from a simulation of a cluster tool found in the literature leads to a different, more concise and illuminating cluster tool simulation model that would have been difficult to discover otherwise. The corresponding optimal scheduling problem is surprising in that it does not include explicit representation of the resource that is actually being scheduled!

Integrating discrete-event simulation with statistical process control charts for transitions in a m - Winter Simulation Conference Proceedings, 1999

We present a model that integrates real-time process control charting with simulation modeling to illustrate the effects and benefits of SPC charts for quality improvement efforts. The integrated model is particularly significant in addressing transition issues arising from changes in the input material. A case study based on a medical manufacturing .industry process is used to illustrate the a...

History of the winter simulation conference: Coming-of-age period (1983-1992)

This paper presents the history of the Winter Simulation Conference (WSC) for the time period covering 1983–1992. This was a healthy era of growth for WSC as conference attendance was strong, exhibits were added, proceedings became hardback, program tracks were added, the Ph.D. Colloquium was initiated, and the Twenty-Fifth Anniversary of WSC was celebrated in 1992. This article discusses all o...

Proceedings of the 1989 Winter . Simulation Conference

This paper provides an introduction to the Johnson translation system of probability distributions, and it describes methods for using the Johnson system to model input processes in simulation experiments. For situations in which little or no sample information is available, we have developed a visual interactive method to estimate bounded Johnson distributions subjectively; and we have impleme...
