Modeling and simulating dynamical system is an autonomous problem in sciences and engineering. General methodologies have been proposed in the following fields sciences, general system theory, the control theory, the economy and lately in artificial intelligence. These different methodologies are necessary because of the granularity and consistency problems. The scientific systems' approximation is based in the mathematical formulation of the dynamical systems, whose strength is based in the modeling an automatic quantitative simulation, which maintains a precise description of the physical systems, to guarantee consistency.
