Example of the graphical method initially the coordinate system is drawn and each variable is associated to an axis (generally 'x' is associated to the horizontal axis and 'y' to the vertical one), as shown in figure 1. Linear programming aconciseintroduction thomas s ferguson here is a simple example find numbers x 1 and x 2 that maximize the sum x 1 + x 2 subject to the . Complete example of the two-phase method in 3x3 dimensions: we put the slack variables to transform the problem into a linear programming problem with equalities and put the artificial variables in case we need an identity submatrix to start the iterations. Example of simplex procedure for a standard linear programming problem: below is the original problem: objective function is in green see step 1: red variables below .
We can motivate our discussion of duality in linear programming by considering again the simple example given in chapter 2 involving the ﬁrm producing three types of automobile trailers recall that the decision.
