Abstract:
Interactive multiple goal linear programming model for dairy farming on sandy soils in the Netherlands. Economic, environmental and landscape goals are considered in an integrated way. It is a static model, figures are expressed per hectare per year. It can be used to explore possible developments in dairy farming with respect to a varying set of goals and constraints. N flows and losses get much attention. Crops considered are: grass, maize and fodder beet. An input-output table is generated by using a Technical Coefficient Generator for those crops, of which GRASMOD* is an example. Purpose of the model:
Model parentage: New.
