Systems' complexity increase as rises the range of possible assumptions to be considered, the level of detail required for the solutions, the flexibility with which we want to count to build alternatives, or the range of points of view from the that observe an operation. The incorporation of dynamic factors, indirect effects, as well as of surrogated operational models in a global model, requires customized and advanced modeling and representation techniques.

Our models allow to display, in an orderly and gradual way, large and complex systems embodying large amount of information of different levels of detail. The employed approach makes it possible to contrast the validity of different alternatives, compare them, and observe their results from different perspectives without losing the overall vision.
