RESUMO

This work proposes a refinementof the simplex method especialized for solving Piecewise-Linear Network Programs, named MSFV. Such a refinement is an extension of the strongly feasible bases concept for Network Programs, developed by W.H. Cunningham. Strongly feasibility is preserved by a specific leaving variable selection rule at each simplex ite~ation. It is proved that the use of strong feasibility together with adequate entering variable selection rules prevents two phenomena cycling (ciclic sequence of degenerate iterations) and stall ing (exponentially long sequence of degenerated iterations). Moreover it is reported a computational testing of MSFV linked with several entering variable selection rules. In addition, it is investigated the performance of MSFV with theScaling Technique, proposed by Edmonds and Karp.
