# Linear Programming : Optimizing Acreage of an Olive Farm

The seasonal yield of olives in a Pireaus, Greece, vineyard is greatly influenced by a process of branch pruning. If olive trees are pruned every two weeks, output is increased. The pruning process, however, requires considerably more labor than permitting the olives to grow on their own and results in a smaller size olive. It also, though, permits olive trees to be spaced closer together. The yield of one barrel of olives by pruning requires 5 hours of labor and 1 acre of land. The production of a barrel of olives by the normal process requires only 2 labor hours, but takes 2 acres of land. An olive grower has 250 hours of labor available and a total of 150 acres for growing. Because of the olive size difference, a barrel of olives produced on pruned trees sells for \$20, whereas a barrel of regular olives has a market price of \$30. The grower has determined that because of uncertain demand, no more than 40 barrels of pruned olives should be produced.

a. Formulate a linear programming model that can be used to determine the maximum possible profit contribution for the grower.

c. Determine the number of acres that the olive grower should devote to each growing process.

#### Solution Preview

Let x represent the number of barrels of pruned olives and y represent the number of barrels of normal olives. Now let's analyze this problem.

1. The yield of one barrel of olives by pruning requires 5 hours of labor and 1 acre of land. The production of a barrel of olives by the normal process requires only 2 labor hours, but takes 2 acres of land. Thus totally there are 5x+2y labor hours and x+2y acres of land.
2. An olive grower ...

#### Solution Summary
