Using a submodular inequality, and the observation that the flow values in capacitated fixed charge networks are often submodular, a family of valid inequalities is derived for such networks that include many of the inequalities derived recently. Potentially these results can be used to obtain stronger formulations for a variety of capacitated production planning and network design problems.
