Simplex method step by step procedure
WebbSimplex Method is a matrix based method used for solving linear programming problems with many variables. It provides us with an iterative technique of examining the vertices of the feasible region that is not optimal, but serves as a starting point.

WebbThe Simplex Method is the name given to the solution algorithm for solving LP problems developed by George B. Dantzig in 1947. It is iterative procedure having fixed computational rules that leads to a solution to the problem in a finite number of steps. By using this one is capable of solving large LP problems efficiently. WebbLet us further emphasize the implications of solving these problems by the simplex method. The opti-mality conditions of the simplex method require that the reduced costs of basic variables be zero. Hence, if xˆ1 > 0, then c1 =6 −1 2 yˆ1 − ˆy2 =0; if xˆ3 > 0, then c3 =13 − ˆy1 −4yˆ2 =0.
WebbThere are not any positive coefficients in the highlighted row. Therefore, the maximum value of the function F was found. The coefficient is zero at position 5 in the highlighted row. There is not a basic variable in the column 5. This allows us to find another solution in which F = 6. Step №3. x 1. x 2.
