A flavor-dependent model (FDM) is proposed in this work. The model extends the Standard Model by an extra local gauge group, two scalar doublets, one scalar singlet and two right-handed neutrinos, where the additional charges are related to the particles’ flavor. The new fermion sector in the FDM can explain the flavor mixings puzzle and the mass hierarchy puzzle simultaneously, and the nonzero Majorana neutrino masses can be obtained naturally by the Type I see-saw mechanism. In addition, the B meson rare decay processes 
the top quark rare decay processes 
and the 
lepton flavor violation processes 
predicted in the FDM are analyzed.
