# Transshipment problem

### From Glossary

This is an extension of the transportation problem whereby the network is not bipartite. Additional nodes serve as transshipment points, rather than provide supply or final consumption. The network is N = [V, A], where V is an arbitrary set of nodes, except that it contains a non-empty subset of supply nodes (where there is external supply) and a nonempty subset of demand nodes (where there is external demand). A is an arbitrary set of arcs, and there could also be capacity constraints.
