In network design problems,capacity constraints are modeled in three different ways depending on the application: directed, bidirected and undirected. In the literature, polyhedral investigations for strengthening mixed-integer formulations are done separately for each model. In this note, we examine the relationship between these models to provide a unifying approach and show that one can indeed translate valid inequalities from one to the others.
