Some New Results in Linear Programming Problems with Fuzzy Cost Coefficients

Blog Article

The fuzzy primal simplex method proposed by Mahdavi-Amiri et al.and the fuzzy dual simplex method proposed by SH Nasseri and A Ebrahimnejad are two current procedures for solving linear programming problems with fuzzy cost coefficients known as reduced fuzzy numbers linear Toadstools programming (RFNLP) problems.In this paper, we prove that in the absence of degeneracy these fuzzy methods stop in a finite numbers of iterations.We also prove the fundamental Hand Pulse Sensor Wire theorem of linear programming in a crisp environment to a fuzzy one.

Finally, we illustrate our proof by use of a numerical example.
