Simulation is one of the most frequently used techniques for modeling
manufacturing and other systems found in modern enterprises. Most simu
lation models are built with either a traditional programming language
such as FORTRAN or a simulation software package written in a traditi
onal 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 busines
s systems. However, many professionals engaged in modeling systems in
enterprises are not yet familiar with the technology. This article pro
vides a succinct introduction to object-oriented concepts and presents
an intuitive methodology for building object-oriented simulation mode
ls. The methodology, which is based on the ideas of actors and scripts
, is illustrated with queuing models. The advantages and limitations o
f the methodology are discussed. (C) 1997 by Elsevier Science Inc.
