WebbThe solution is the two-phase simplex method. In this method, we: 1.Solve an auxiliary problem, which has a built-in starting point, to determine if the original linear program is feasible. If we succeed, we nd a basic feasible solution to the orignal LP. 2.From that basic feasible solution, solve the linear program the way we’ve done it before. WebbDual Simplex Method: Iterative steps involved in the dual simplex method are: 1. All the constraints (except those with equality (=) sign) are modified to ‘less-than-equal-to’ sign. Constraints with greater-than-equal-to’ sign are multiplied by -1 through out so that inequality sign gets reversed. diasorin s.p.a uk branch
