In mining complexes or mineral value chains, materials flow from extraction sites (mines) through crushers, stockpiles, waste dump and tailings, and processi...

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 ...

The water pump scheduling problem is an optimisation model that determines which water pumps will be turned on or off at each time period over a given time h...

Bilevel optimization has garnered growing interest over the past decade. However, little attention has been paid to detecting and dealing with unboundedness...

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. ...

Mean Field Game equilibria are based on the assumption of instantaneous interactions within a population of interchangeable agents, where each agent's impact...

In this paper, we address the problem of online estimation of spherical features in the field of camera for robotics. Specifically, we consider a mobile robo...

The central limit theorem is a fundamental result in probability theory that characterizes the distribution of deviation from the mean in the law of large nu...

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 consider chemical graphs that are defined as connected graphs of maximum degree at most 3. We characterize the extremal ones, that is, those that maximize...

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

Blending problems occur when different components are mixed to form an end product. The recipe typically has some flexibility as long as specific quality con...

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...

Integrating Optical Transport Networks (OTNs) into multilayer Elastic Optical Networks (EONs) enhances data transmission efficiency but introduces significan...

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

The procurement of freight services is an important element for the supply chain management of a shipper (i.e., a manufacturer or retailer) that sources tran...
