Decision-based scenario clustering and its applications for decision-making under uncertainty Date and Place Friday, December 2nd 2022, 11h00, Inria de l’Université de Lille Abstract: In order to make sense of future uncertainty, managers have long resorted to creating scenarios that are then used to evaluate how uncertainty affects decision-making. The…
Date: Monday, May 30th 2022, 10h00 Place: Inria Lille-Nord Europe Optimizing Pricing, Repositioning, Pickup Time, and Idle Time in Ride-Hailing Systems Abstract: In ride-hailing systems, pickup time refers to the time that elapses from the moment a vehicle is dispatched to pick up a rider until the rider is picked…
Date: December, 6th, 14h00 Place: Inria Lille-Nord Europe Gaël Guillot: Optimal pricing for electric vehicle charging with customer waiting time. Abstract: We propose a bilevel optimization model to determine the optimal pricing for electric vehicle within a public charging station system by taking into account the waiting time of customers.…
Date: October, 21st, 11h30 Place: Inria Lille-Nord Europe Abstract: In internal warehousing logistics, the placement of the different items, i.e. SKU (Single Keeping Units), is one of the most impactful decision on the performance of warehouse activities. In the related literature, the Storage Location Assignment Problem (SLAP) has been extensively studied,…
Date: October, 4th, 14H30 Place: Inria Lille-Nord Europe Abstract: Uncertainty in classical stochastic programming models is often described solely by independent random parameters, ignoring their dependence on multidimensional features. We propose a novel contextual chance-constrained programming formulation that incorporates features and argue that a solution that ignores them may not…
Date: March, 13th, 11h00 Place: Inria Lille-Nord Europe Abstract: We have all experimented recommender systems on the web, whether it’s for choosing a movie, a book, a restaurant, or a holiday destination. Roughly speaking, a recommender system is a platform that seeks to predict the rating or preference that a…
Date: January, 23rd, 11h00 Place: Université Libre de Bruxelles Abstract: Optimization models for Air Traffic Flow Management (ATFM) select, for each flight, suitable trajectories with the aim of reducing congestion of both airports and en-route sectors, and maximizing the Air Traffic Management system efficiency. Recent models try to include as…
Date: July, 16th, 10h00 Place: Inria Lille-Nord Europe Abstract: Demand response is a valuable resource in the smart grid. It has been proved that demand response can improve the reliability of the grid while decreasing load consumption at peak time. Aggregators play a major role in the smart grid: as…
Date: March, 27th, 12h15 Place: Université Libre de Bruxelles Abstract: Hubbing is commonly used in airlines, cargo delivery and telecommunications networks where traffic from many origins to many destinations are consolidated at hubs and are routed together to benefit from economies of scale. Each application area has its own specific…
Date: March, 26th, 11h00 Place: Université Libre de Bruxelles Abstract: In this talk, we present diverse concepts: Variable Neighborhood Search, Variable Neighborhood Descent, parallel algorithm, shared memory, message passing interface and community detection. Besides, we explain how can we use all of them in only one algorithm. Some numerical results…
