This paper presents a linear programming model for farm planning known as the “Purdue Top Farmer Cropping Model ‘B’.” This model is designed for direct use with farmers and has been used by more than 5,000 individuals. The paper describes the features of this model and discusses the rationale for these features. In this process details on application, evolution and impact of the model are given. The success of the model is due to its design and the interplay between research and extension personnel in the model design.
Un modele de programmation lineaire, connu sous le nom de “Purdue Top Farmer Cropping Model ‘B’,” et destine a la planification de la production des exploitations agricoles, est presente dans ce rapport. Le modele, deja employe par plus de 5000 individus, est construit de maniere a etre directement utilisable par les exploitants agricoles. Le rapport decrit et expose la raison d'etre des caracteristiques du modele. Des details sur les applications, l'evolution et l'impact de ce dernier sont fournis. La collaboration entre Je personel de recherche et d'extension dans le dessin du modele en explique le succes.
