Scheduling locks on inland waterways

Locks are typical bottlenecks along rivers and canals. We consider a system of multiple locks arranged in a sequence, a setting that occurs naturally along many inland waterways. To optimize the decision-making of these locks, we present different mathematical programming formulations, focusing on the travel time objective as well as the emission of pollutants. We then use these models to investigate the potential gains in performance, and the trade-off between the different objectives.status: publishe
