Valid Inequalities for Potential-Based Network Design Including Compressors

Categories (Mixed) Integer Linear Programming Tags ,

We study the steady-state expansion problem for potential-based flow networks. Constructing a cost-minimal network that admits a flow satisfying the underlying physical laws is a central problem in the design of gas, hydrogen, water, and electricity infrastructures. The physical behavior of such networks is governed by nonlinear relations between arc flows and the potential differences … Read more

A two-stage optimization approach for selecting electric-flight airports

Categories Applications - OR and Management Sciences, Transportation Tags , , , ,

The decarbonization of short-haul air transport has gained increasing attention, with electric aircraft emerging as a promising alternative to conventional short-haul aviation. However, given the substantial investment anticipated for the necessary infrastructure, a strategic and globally coordinated selection of airports is imperative. The aim of this paper is to address this problem and determine the … Read more
