Classical duality and existence results for a multi-criteria supply-demand network equilibrium model

Research output: Journal article publicationJournal articleAcademic researchpeer-review


We propose a dual model of a multi-criteria network equilibrium model and establish a primal-dual relationship between the network model and its dual model under certain generalized monotonicity assumptions. By using Gerstewitz's function, we obtain the primal-dual relationship without any convexity assumptions. As an application of the dual model, we derive an existence result for the network model.
