ABSTRACT
The word simulation refers to the treatment of a real problem through reproduction in an environment controlled by the experimenter. The environment is often provided by computational equipment although it can be a smaller scale reproduction of the system under study. An example is the study of tides in a laboratory reservoir. In this controlled environment, the water movement is caused by a device that is governed by an electric engine. This constitutes a study of a system that has all its components known or at least deductible and whose behavior has an intrinsic deterministic character.
