Revenus, marchés et anticipations : la dynamique de l'offre agricole

One main limit of linear programming models is that all the parameters (prices, yields, input-output coefficients) are supposed known with certainty. There, this assumption is relaxed to take in account the risk attitude of the farmers. The risk is measured by the mean absolute deviation like in the MOTAD method. MOTAD approximation is generalised to problems where all parameters are stochastic. A new formulation is used to model the behaviour of polycultural farms with reference to milk production in the Forez region.
