Maximize 5X1 + 3X2 Find the optimal simplex tableau by performing pivoting operations. Identify the optimal solution from the optimal simplex tableau. In the last chapter, we used the geometrical method to solve linear programming problems, but the geometrical approach will not work for problems that have more than two variables. Define tableau.

The bottom row comes from setting the equation M = 60x + 90y + 300z to 0, i.e, -60x - 90y - 300z + M = 0. Choosing the PIVOT COLUMN. 2006-06-19 The simplex procedure can be summarised as follows: 1. Find the pivot column – the column that has the greatest positive entry in the Cj −Z j row. If there are no positive entries in a tableau, it means that the optimal solution has already been reached.
