Linear programming, an optimizing mathematical programming technique, is applied to the problem of allocating space with a greenhouse range to crops in such a way as to maximize profits.
Space is a primary cost of production.
Other major costs are fuel for heating, labor and materials.
All these costs were included in the problem formulation.
Aside from space limitations, the other constraints on production volume are those dictated by the market and by management preferences.
The total space available dictates an upper limit on total crop volume and the amount the market will absorb may dictate upper limits on individual crops varying by season.
Lower limits on crops may be dictated by contractual obligations or by management preferences.
These limits are represented in the problem formulation.
An example of a simple problem formulation and the output is presented here.
