Actors and scripts: Object-oriented simulation of enterprise systems

Abstract

Simulation is one of the most frequently used techniques for modeling manufacturing and other systems found in modern enterprises. Most simulation models are built with either a traditional programming language such as FORTRAN or a simulation software package written in a traditional programming language. These tools have their limitations. Object-oriented technology has seen increasing application in many fields and promises a more flexible and efficient approach to simulating business systems. However, many professionals engaged in modeling systems in enterprises are not yet familiar with the technology. This article provides a succinct introduction to object-oriented concepts and presents an intuitive methodology for building object-oriented simulation models. The methodology, which is based on the ideas of actors and scripts, is illustrated with queuing models. The advantages and limitations of the methodology are discussed.
