Henig efficiency of a multi-criterion supply-demand network equilibrium model

Research output: Journal article publicationJournal articleAcademic researchpeer-review


This paper addresses Henig efficiency of a multi-product network equilibrium model based on Wardrop’s principle. We show that in both the single and multiple criteria cases, such proper efficiency can be recast as a vector variational inequality. In the multiple criteria case, we derive a sufficient and a necessary condition for Henig efficiency in terms of a vector variational inequality by using the Gerstewitz’s function.
