Description of the Types of Maximum Noninteger Vertices of the Polyhedron in the Three-Index Axial Assignment Problem

For an arbitrary r ∈ {3n − 4, 3n − 3, 3n − 2}, a description of all the types of r-noninteger vertices (i.e., the vertices with r fractional components) of the polyhedron of the three-index axial assignment problem of order n with n ≥ 4 is proposed.
