in this paper, a discrete event simulation model of iranian railway system is used for analyzing performance of the system in freight sector. the model analysis shows more sensitivity of the system on loading and unloading facilities than on number of wagons and locomotives. system optimization through simulation optimization technique, shows that more than 4% of all wagons available in the net...

Simulation has been used traditionally to solve other areas problems. Real time applications like videogames use typically a continuous simulation scheme. That way of operation has disadvantages that can be avoided using a discrete event simulator as a game kernel. This paper proposes the integration of a discrete event simulator into real time applications to control the applications simulatio...

Discrete-event simulation based optimization is the process of finding the optimum design of a stochastic system when the performance measure(s) could only be estimated via simulation. Randomness in simulation outputs often challenges the correct selection of the optimum. We propose an algorithm that merges Ranking and Selection procedures with a large class of random search methods for continu...

We describe the use of discrete event simulation in modeling the curbside vehicular traffic at airports. The dynamic nature of vehicular traffic poses a challenge in developing a discrete event simulation model to represent roadway operations. We present our simulation methodology in modeling the new Austin-Bergstrom International Airport and address the use of simulation in the design as well ...

Spreadsheet simulation" refers to the use of a spreadsheet as a platform for representing simulation models and performing simulation experiments. authoritative source on the theory & practice of simulation over 15 years ago. It. Handbook of Simulation Principles, Methodology, Advances, Applications,. By Margery J Doyle in Modeling and Simulation and Stigmergy. In Handbook of Simulation: Princi...

This article describes an implementation of real-time simulation and control in DEVS-Scheme, a knowledge-based, discrete event environment. We illustrate a methodology in which the plant, its actuators and sensors are described by discrete event models developed within the event-based control paradigm. A model of the controller is employed to validate its design in a plant/actuator/sensor exper...
