New commodity representations for multicommodity network flow problems: An application to the fixed-charge network design problem
Ahmad Kazemi, Pierre Le Bodic, Andreas Ernst +1
When solving hard multicommodity network flow problems using an LP-based approach, the number of commodities is a driving factor in the speed at which the LP can be solved, as it i…
Instance Space Analysis for the Car Sequencing Problem
Yuan Sun, Samuel Esler, Dhananjay Thiruvady +3
We investigate an important research question for solving the car sequencing problem, that is, which characteristics make an instance hard to solve? To do so, we carry out an insta…
A linear programming approach to approximating the infinite time reachable set of strictly stable linear control systems
Andreas Ernst, Lars Grüne, Janosch Rieger
We develop a new numerical method for approximating the infinite time reachable set of strictly stable linear control systems. By solving a linear program with a constraint that in…
A hybrid Benders decomposition and bees algorithm matheuristic approach to transmission expansion planning considering energy storage
Cameron A. G. MacRae, Melih Ozlen, Andreas T. Ernst
This paper introduces a novel hybrid optimisation algorithm that combines elements of both metaheuristic search and integer programming. This new matheuristic combines elements of…
