The MM & S software model dynamically structures the system with four groups of factors: the group of elements, the elements of the elements, the groups of elements, the elements of the list. The software enables the drawing of structural simulations (elements and interactions between them), model calculations and time graphs to simulate fluctuations in elements or to plot phase diagrams showing fluctuations. between 2 elements. Mathematical models can be integrated into the simulation or written as text files. Mathematical models can be exported from simulation to text files.
