The Ploughman family has owned and operated a 640-acre farm for several generations. The family now needs to make a decision about the mix of livestock and crops for the coming year. By assuming that normal weather conditions will prevail next year, a linear programming model can be formulated and solved to guide this decision. However, adverse weather conditions would harm the crops and greatly reduce the resulting value. Therefore, considerable postoptimality analysis is needed to explore the effect of several possible scenarios for the weather next year and the implications for the family’s decision.
