Abstract

In the studies done by the author about dynamic systems modelling, the basic concepts of systems and their application to ecological model theory have been formalised (Villacampa et al [3]). In the dynamic risk system modelling, it is not possible to obtain a system as a model, because it would suppose knowledge over reality. Moreover, it is usual to consider that a model is more real when more variables are studied and when there are a lot of relationships between them. It has been checked that the increase of parameter does not contribute to obtaining a better simulation. It is necessary to define measurements to improve the dynamic systems modelling. In
