Simplex method artificial variables

Webb26 sep. 2024 · The artificial variable technique is a device to get the starting basic feasible solution, so that simplex procedure may be adopted as usual until the optimal solution is obtained. To solve such LPP there are two methods. (i) The Big M Method or Method of Penalties. (ii) The Two-phase Simplex Method. The Big M Method: WebbSimplex Method Step 5: Calculate cj-zj Row for New Tableau •For each column j, subtract the zj row from the cj row. •If none of the values in the cj-zj row are positive, GO TO STEP …
