What is the difference between simplex method and Big M method?

WebbThe Two-Phase Simplex Method When a basic feasible solution is not readily available, the two-phase simplex method may be used as an alternative to the Big M method. In the two-phase simplex method, we add artificial variables to the same constraints as we did in the Big M method. Then we find a bfs to the original LP by solving the Phase I LP. http://www.linprog.com/ http://connectioncenter.3m.com/solved+examples+of+simplex+method+in+operation+research flitsers a9
