4.2: MAXIMIZATION BY THE SIMPLEX METHOD - MATHEMATICS …
From math.libretexts.org
- Set up the problem. Write the objective function and the constraints. Since the simplex method is used for problems that consist of many variables, it is not practical to use the variables \(x\), \(y\), \(z\) etc.
- Convert the inequalities into equations. This is done by adding one slack variable for each inequality. For example to convert the inequality \(x_1 + x_2 ≤ 12\) into an equation, we add a non-negative variable \(y_1\), and we get.
- Construct the initial simplex tableau. Each inequality constraint appears in its own row. (The non-negativity constraints do not appear as rows in the simplex tableau.)
- The most negative entry in the bottom row identifies the pivot column. The most negative entry in the bottom row is -40; therefore the column 1 is identified.
- Calculate the quotients. The smallest quotient identifies a row. The element in the intersection of the column identified in step 4 and the row identified in this step is identified as the pivot element.
