The bid construction problem (BCP) for combinatorial total truckload transportation service procurement auctions consists of determining one or several bids ...

Personnel scheduling consists of determining least-cost employee work schedules to cover the demand of one or several jobs in each period of a time horizon. ...

La méthode de branch-cut-and-price est la plus performante pour une grande panoplie de problèmes de tournées de véhicules (PTV). Pour plusieurs d'entre eux...

In this paper, we propose an integer programming model for obtaining lower bounds for the curriculum-based course timetabling problem, in which weekly assign...

Synchronization of workers and vehicles plays a major role in many industries such as logistics, healthcare or airport ground handling. In this paper, we fo...

La création d’horaires de personnel aériens est généralement effectuée en deux étapes : la création de rotations d’équipage, suivie par la création d’horaire...

We study a rich production-routing problem with time windows arising at a catering services company. The production part consists of assembling the meals to ...

The vehicle routing problem with time windows (VRPTW) consists of finding least-cost vehicle routes to satisfy the demands of customers that can be visited...

Inventory routing problems aim at minimizing the cost of the total distance traveled over a time horizon discretized in periods, while guaranteeing that th...

This paper introduces the pickup and delivery problem with time windows and handling operations. In this problem, the loading compartment of a vehicle is mod...

Given a flight schedule and a set of aircraft of different types, the airline fleet assignment problem (FAP) consists of assigning an aircraft type to each f...

The tail assignment problem is a critical part of the airline planning process that assigns specific aircraft to sequences of flights, called lines-of-flight...

Cet article traite la prise en compte d'incertitudes lors de la résolution de conflits. Plus particulièrement, nous considérons les incertitudes dues aux err...

Nous présentons un modèle déterministe pour le problème de détection et de résolution de conflits entre aéronefs. Les aspects liés à la dynamique des avions,...

This paper introduces a new primal algorithm for solving a linear program LP. In this algorithm, a pricing problem, namely a linear fractional program, is ...

Dans cet article, nous étudions des stratégies pour résoudre le problème de partitionnement d'ensemble (PPE), en particulier les gains en efficacité qui pe...

This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and multiple stacks. Each stack is rear-loade...

Effective route planning for battery electric commercial vehicle (ECV) fleets has to take into account their limited autonomy and the possibility of visiting...

Including employee preferences in a shift-scheduling scheme raises the question of how to aggregate employee satisfactions in a sensible manner. To do so, we...

In this article, we solve the pickup and delivery problem with time windows and last-in-first-out (LIFO) loading. LIFO loading minimizes handling while unloa...
