In this paper, linear programming model was applied to Sharks bread Production Company to determine the right product-mix and quantities that maximize the company’s daily profit. In this lecture, we will be covering different examples of LP, and present an algorithm A linear program in canonical form can be replaced by a linear program in standard form by just replacing Ax ≤b by Ax + Is = b, s ≥0 where s is a vector of slack variables and I is the m×m identity matrix. 2: Maximization By The Simplex Method The simplex method uses an approach that is very efficient. Similarly, a linear program in standard form can be replaced by a linear program in canonical form by replacing Ax = b by A′x ≤b Applications of the method of linear programming were first seriously attempted in the late 1930s by the Soviet mathematician Leonid Kantorovich and by the American economist Wassily Leontief in the areas of manufacturing schedules and of economics, respectively, but their work was ignored for decades. Design an appropriate linear programming model for this investment problem. ~George Dantzig. Like one of LP's applications, the assignment concerns a private Linear Programming Simplex Method Applications Linear Programming The Simplex Method was developed by George Dantzig in 1947. Most of the optimization works happen on linear programming for solving complex problems. As a result, the feasible solution extends indefinitely to the upper right of the first quadrant, and is unbounded.
