INTRODUCTION The detection of the neutral CP-even Higgs with mass around 125 GeV by experiment at LHC [1, 2] has again confirmed the success of the Standard Model (SM). Beside that many other well-known results of experiments suggest the necessary to study new models beyond the SM, for example the non-zero mass and the oscillation of neutrinos, the existence of dark matter in the universe, the hierachy in mass spectrum of the SM, the question of the existence of three fermion families, Among the well-known models beyond the SM, the supersymmetric minimal reduced 33-1 model (SUSYRM331) was recently built with many interesting properties. It is the supersymmetric version of the reduced minimal 3-3-1 model (RM331) [3] which contains the simplest Higgs content comparing with well-known 3-3-1 models. It is noted that the SUSYRM331 not only keeps many interesting property of the RM331 model but also
