Biological functions are the result of the interaction of many processes that connect different hierarchy levels going from macroscopic to microscopic level. Each process works in different way, and it is common to observe that changes in the conditions, such as nutrients or environment, modify the behavior of the systems. To approach these elements we consider the Hybrid Systems theory, which is adapted to reuse and reconcile models a priori validated. The aim in wine fermentation control is to predict fermentation problems in time to save them. Several models have been built trying to...
