Linear programming graphical method This method is suitable for problems with only two decision variables. It involves plotting the constraints on a graph and visually identifying the optimal solution. Example: Maximize Z = 3x + 2y Subject to: 2x + y ≤ 10 x + 2y ≤ 8 x, y ≥ 0 Solutio...
In the interest of being compact (and again, building toward the general linear programming formulation) we can extract the price information into a single cost vector c=(0.381,0.1,0.272), and likewise write our variables as a vector x=(b,m,r). We’re implicitly fixing an ordering on the...

LINEAR PROGRAMMING 1. Introduction. A linear programming problem may be defined as the problem of maximizing or min- imizing a linear function subject to linear constraints. The constraints may be equalities or inequalities. Here is a simple example. ...

To apply LP, the objective function was transformed into a linear function using a method based on goal programming, as described elsewhere (17,20). For this purpose, new decision variables (ϵ R+) P1 to Pj and N1 to NJ, which represented the positive and the negative deviations from ob...
Integer linear programming is a method ofoptimizing a linear cost function, and it should satisfy a variety of restrictions on linear equality andlinear inequality.It’s an extension of linear programming, with an additional constraint, stating that all variables should be integers.Let’s define an...
