ABSTRACT
Linear programming is a modeling tool that can assist in the solution of many problems in agriculture. In particular, linear programming is useful in selecting the best alternative from a number of available courses of action. A linear programming problem consists of three major components: Decision variables, Objective function and Constraints. Identifying and formulating linear programming problems is as much as an art as it is a science. The graphical view of linear programming portrays very clearly the formation of the region of feasible solutions using linear equations. It also demonstrates that the optimal solution of a linear programming problem is a solution to the set of simultaneous linear equations derived from the constraint inequalities and equalities. There are five groups of constraints in the linear programming formulation of the land forming design problem. The first two are similar, one for the cross-row direction and one for the row direction, and represent the majority of the constraints.
