Algebraic and combinatorial methods in operations research, Proc. Workshop, Ann. Discrete Math. 19, 257-356 (1984).

The authors have developed a generalized version of the substitution decomposition known for Boolean functions, set systems and relations and their applications. It is shown how a general factorization problem in combinatorial optimization over graphs, project networks, partial orders, etc., naturally leads to this kind of decomposition. A general algebraic model of the decomposition is provided. This paper can be regarded as an important step on the way to an algebraic decomposition theory in discrete mathematics.
