Each pair of this class defines a unique binary matrix. These pairs of vectors and matrices are said to be extremal. It is shown that any transportation pair of vectors and any transportation matrix may be represented in the form of a convex linear combination of extre- mal (standard) elements.  Ключевые слова transportation polyhedron, transportation models, extremal matrices and vectors
