                                                                                  Introduction


                     Instead of studying actual situations that sometimes might be too costly, too
                     dangerous, or too time consuming, researchers create similar situations using
                     random devices so that they are less expensive, less dangerous or less time
                     consuming. For example, pilots use flight simulators to practice on before
                     they actually fly a real plane. Many video games use the computer to simulate
                     real life sports situations such as baseball, football, or hockey.
                        Simulation techniques date back to ancient times when the game of chess
                     was invented to simulate warfare. Modern techniques date to the mid-1940s
                     when two physicists, John von Neuman and Stanislaw Ulam developed si-
                     mulation techniques to study the behavior of neutrons in the design of atomic
                     reactors.
                        Mathematical simulation techniques use random number devices along
                     with probability to create conditions similar to those found in real life.
