Indeed, transportation problem is approached as a linear programming problem which can be solved by simplex method using linear programming. Linear Programming is a powerful problem solving tool that aids management in making decisions. The feasible region is bounded and nonempty. Thus if the ploblem has optimal solution, it will be finite. In addition the objective function grows in the direction of growth of x and y coordinates, the problem has finite optimal solution into of the extreme points of feasible region. The cost of transportation from one supply point to one destination varies linearly with the quantity supplied. Indeed, transportation problem is approached as a linear programming problem which can be solved by simplex method using linear programming.

Answers to LP: Introduction and Graphical Methods for Maximization Problems Dr. Jaya Singhal 1. Find the optimal solution of the following linear programming problem using the Corner Points Method. Max 3x + 5y Subject to 4x + y > 4 3x + 2y < 12 x, y > 0 Answer: Constraint 4x + y ≥ 4: The corresponding equation is 4x + y = 4. An optimal solution to a linear programming problem can be found at an extreme point of the feasible region for the problem. True An infeasible problem is one in which the objective function can be increased to infinity. The simplex method is applicable to any problem that can be formulated in-terms of linear objective function subject to a set of linear constraints. The simplex method provides an algorithm which is based on the fundamental theorem of linear programming. This states that “the optimal solution to a linear programming problem if it exists ... Simplex Method: It is one of the solution method used in linear programming problems that involves two variables or a large number of constraint. The solution for constraints equation with nonzero variables is called as basic variables. It is the systematic way of finding the optimal value of the objective function. 5.

In this case, the equation 2y + x = c is known as the linear objective function. Rewriting 2y + x = c as y = – x + c, we find that the gradient of the line is – . To find the optimal solution to a linear programming problem, we must first identify a set, or region, of feasible solutions. The first step in doing so is to plot the problem’s constraints on a graph.
