WebbThe simplex method is an appropriate method for solving a ≤ type linear programming problem with more than two decision variables. Two phase and M-method are used to solve problems of ≥ or ≤ type constraints. Further, the simplex method can also identify multiple, unbounded and infeasible problems. Share this article with your friends WebbIt is known as the simplex method. This is a classic method that has been in use for many years. The reader may wish to consult G. Hadley's Linear Programming published by Addison-Wesley in 1963 for the theoretical underpinnings of this algorithm. WebbUsing simplex method make iterations till an optimal basic feasible solution for it is obtained. It may be noted that the new objective function W is always of minimization type regardless of whether the given (original ) L.P.P. is of maximization or minimization type. Let us take the following example. Example 1 (Two phase simplex Method): fd2 type-r
