An ALNS Heuristic for Large-Scale Line Planning with Mode Choice and Line Generation
Siv Marie Cartland Hansen, Richard Martin Lusby, Rowan Hoogervorst +1
The paper presents a scalable Adaptive Large Neighborhood Search algorithm that jointly designs public transport lines, frequencies, and passenger assignments while accounting for…
A column generation-based fixed-point heuristic for the service-aware multi-commodity flow problem
Siv Marie Cartland Hansen, Richard Martin Lusby
We study the Service-Aware Multi-Commodity Flow (SAMCF) problem, in which demand is elastic and governed by a logit choice model while routing is subject to hard capacity constrain…
An Exact Algorithm for Public Transport Line Planning Considering Passenger and Operational Costs and Lost Demand
Siv Marie Cartland Hansen, Rowan Hoogervorst, Otto Anker Nielsen +2
Line planning in public transport is the strategic problem of selecting lines and their operating frequencies. This problem is important as it defines the passenger service, based…
Sufficient A Priori Conditions for the Linear Relaxation of the Energy Storage Scheduling Problem
Eléa Prat, Richard Martin Lusby, Pierre Pinson
When modeling energy storage systems, an essential question is how to account for the physical infeasibility of simultaneous charge and discharge. The use of complementarity constr…
How long is long enough? Finite-horizon approximation of energy storage scheduling problems
Eléa Prat, Richard M. Lusby, Juan Miguel Morales +2
Energy storage scheduling problems, where a storage is operated to maximize its profit in response to a price signal, are essentially infinite-horizon optimization problems as stor…
Multistage stochastic optimization for drayage procurement in container logistics using stochastic dual dynamic programming
Georgios Vassos, Richard Lusby, Pierre Pinson
Truckload procurement plays a vital role in integrated container logistics, particularly under the uncertainties of container flow and market conditions. We formulate the operation…
