From the antiquity the man has used the processes *biotecnológicos for the obtaining of products of interest. In the actuality, the sector *biotecnológico is one of the areas that is experiencing a greater growth, what comports the need to select, inside a space of possibilities, those alternatives that in base to a criterion predetermined, allow to fulfil with the aims wished. The research of a formal approach of the problem of design promotes the need to find mathematical models that adjust to the empirical data and that allow a greater ease in the optimisation and simulation of said processes. All this *redundará in a greater efficiency and ease of control of diversity of processes with base *biotecnológica
