In multi-period farm planning problems involving uncertainty, the usual case in the real world, planning must involve a continuous process of re-evaluation. In this dynamic situation it is necessary to know the number of periods to include in the decision model to ensure optimality. This is...

Farm planning in the non-certain world is complex so that models which adequately represent this situation are difficult and expensive to experiment with. Thus a range of linear programming models based on simplifications has been suggested for planning under non-certainty. This discussion...
