It is an optimisation technique that focuses on providing the optimal solution for allocating available resources amongst different competing and conflicting requirements. Theorem: Fundamental Theorem of Linear Programming. If a linear programming problem has a solution, then the solution always occurs at a corner point. If two adjacent corner points give solutions, then every point on the line segment connecting them also give that solution. If the profit function is \(P = ax + by \)

A linear programming problem with a bounded set always has an optimal solution. This means that a bounded set has a maximum value as well as a minimum value. Example 1: Given the objective function P = 10 x − 3 y and the following feasible set, Find the maximum value and the point where the maximum occurs.

The Maximization Linear Programming Problems. Define the unknowns. Write the objective function that needs to be maximized. Write the constraints. For the standard maximization linear programming problems, constraints are of the form: \(ax + by ≤ c\) Since the variables are non-negative, we include the constraints: \(x ≥ 0\); \(y ≥ 0\).
