In this paper, in order to apply the concept of IVI-octahedron sets to MCDGM problems, we define some aggregation operators via IVI-octahedron sets and obtain some their properties. We  define some aggregation operators via IVI-octahedron sets and obtain some their properties.  We present a MCGDM method with linguistic variables in IVI-octahedron set environment. Finally, we give a numerical examples  for MCGDM problems.
