Any MCNFP can be formulated as an LP. It can be also solved by a generalization of the transportation simplex method called the network simplex method.

To define MCNFP, let X ij = number of units of flow sent from node i to node j through arc(i,j) b i = net supply (outflow-inflow) at node i c ij = cost of transporting 1 unit of flow from node i to node j via arc(i,j) L ij = lower bound of flow through arc(i,j) (if there is no lower bound, let L ij =0) U ij = upper bound of flow through arc(i,j) (if there is
