Modélisation des exploitations porcines et de grandes cultures en Bretagne : spatialisation de la demande en aliments du bétail
Résumé
The high proportion of livestock farms in the agriculture in Brittany results in many animal feed factories established in this area. Thereby, the animal feed flows evolution is a major issue for this sector. This paper presents a farm model based on a linear programming approach using a Positive Mathematical Programming calibration procedure which aims at studying the localisation of the supply and demand of animal feed. Agricultural productions modelled thus far are limited to cereals and pork meat in Brittany. We describe the proposed model and explain how it as been calibrated from the available data. Some simple simulations are also presented to illustrate how the model fulfils or not expectations.
