Solving the on-demand bus routing problem

This article investigates a static on-demand transportation problem in which users are picked up and dropped off at existing bus stops. Specifically, we assume that the selection of bus stops for each request, along with the bus routes, is determined …

Gamifying the vehicle routing problem with stochastic requests

Do you remember your first video game console? We remember ours. Decades ago, they provided hours of entertainment. Now, we have repurposed them to solve dynamic and stochastic optimization problems. With deep reinforcement learning methods posting …

A two phase iterative approach using machine learning to solve a gas pipeline surveillance problem (ODYSSEUS)

A technical talk on an heuristic approach to solve the Periodic Capacitated Arc Routing Problem.

Algorithms for solving the on-demand bus routing problem with bus stops assignment (ODYSSEUS)

A technical talk on an heuristic approach to solve the on-demand bus routing problem with bus stops assignment.

Approximer le coût de tournées de surveillance du réseau de transport gazier à l’aide d’apprentissage automatique (ROADEF)

A technical talk on the use of machine learning to approximate routing costs.

Learning implicit multiple time windows in the traveling salesman problem

Classically, researchers working in vehicle routing problems (VRPs) assume that the structure of the problem is known (i.e., objective function, constraints, parameters). However, recent studies have highlighted the gap between the routes offered by …

Dynamic ride-hailing with electric vehicles

We consider the problem of an operator controlling a fleet of electric vehicles for use in a ride-hailing service. The operator, seeking to maximize profit, must assign vehicles to requests as they arise as well as recharge and reposition vehicles in …

Integration of machine learning and operations research to solve more realistic problems (CIRRELT)

An overview talk of past and current research.

Atari-fying the vehicle routing problem with stochastic service requests (CORS)

A technical talk on the new paradigm of atari-fying operations research problems.
