Abstract
The use of computers to model things, both real and imaginary, and the use of those models as surrogates for investigative and experimental purposes, constitute the art and science of simulation.
Since its inception in the late nineteen forties simulation has undergone some interesting evolutionary changes. Paced by the development of rapidly improving computing and allied equip ment, the technology and methodology of simulation have faced — and to varying degrees learned to cope with - changing chal lenges as the ever-widening fields of application have multiplied.
Hard limits are not in sight. However, vestiges of some original problems remain while others have been solved as simulation progresses from an art toward becoming a science.
