In the proposed method, we deal with 1 number of variables, where 1 ≤ and use a strategic move to reduce the feasible convex search space before embarking on the simplex method. The feasible space reduction process can be repeated, if desired. Key words: Linear programming model, Simplex method, Feasible space reduction, Reduced number of variables. 1. Introduction Many solution procedures have been developed for linear programming (LP) models. For example, see Dantzig (1963), Khachiyan (1980), Karmarkar (1984), and many variants of these approaches have been discussed in Forrest and Goldfrab (1992), Gay et al. (1998), Roos et al. (2006), Munapo and Kumar (2013), Small (1983), Vanderbei (2001, 2008), Zadeh (2009). Many other approaches have been suggested by Wright (1997, 1998), Ye (2011) and Zoutendijk (1960). Munapo and Kumar (2013) considered a LP model with non-negative coefficients, and developed
