The crew rostering problem (CRP) for pilots is a complex crew scheduling task assigning pairings, or sequences of flights starting and ending at the same air...

An industrial mining complex is an integrated value chain includes the excavation, transportation, processing, and distribution of mineral products as well a...

On February 4, 2025, the 5th edition of GERAD's Student Day took place, under the theme of energy transition. The aim of this event was to give students the ...

Retailers routinely face the strategic decision of how to promote their products. Two of the most common promotion strategies are bundling and discounting. D...

We develop a worst-case evaluation complexity bound for trust-region methods in the presence of unbounded Hessian approximations. We use the algorithm of ...

This paper considers the problem of designing urban mobility hubs by modeling them as service-integrated hub-line location problems. We integrate traditional...

This paper addresses the problem of efficiently routing vehicles for spring sweeping operations in countries that spread sand and gravel on roads in winter. ...

Motivated by our collaboration with an online platform operating in North America, we explore the joint optimization of the order fulfillment process with pe...

We investigate the impact of information asymmetry regarding the producer of remanufactured products on the decisions of a manufacturer and an authorized r...

A three-region optimal economic growth model is proposed to represent the global energy transition to net-zero emissions when carbon dioxide removal (CDR) te...

Population growth and city sprawl have been driving increasing amounts of traffic congestion in multiple major cities worldwide. In this scenario, developing...

We propose a dynamic stochastic game model to assess the value of restrictive clauses in private loan contracts. Restrictive clauses are used by lenders to m...

We propose some diagonal Hessian approximations of the least-squares nonlinear function. We use suitable diagonal matrices that carry some information of the...

In the multi-commodity two-echelon vehicle routing problem with time windows (MC-2E-VRPTW), first-echelon vehicles transport goods from depots to satellites...

Planners in different industries use optimization software for decision-making. In numerous practical applications, these optimization tools are often not re...

This study investigates the feasibility of large-scale distributed networks. The core focus of our research is the impact of multi-hop communication on point...

The Fourteenth Montreal Industrial Problem Solving Workshop, held May 13-17, 2024, was jointly organized by the Centre de recherches mathématiques (CRM), the...

This paper addresses the Integrated Electrical Drill Rig Dispatching and Drilling Coordination Problem (IDRDCP) in open-pit mining operations, combining mach...

The routing-and-driving problem for plug-in hybrid electric vehicles (PHEVs) is an extension of the vehicle routing problem with time windows, where routing ...

Managing intermittent generation in electric power systems with high penetration of renewable sources of energy presents major operational challenges. Faster...
