Seminar: Thibault Prunet, Thursday, October, 21st 2021 -Storage Location Assignment in Forward Area: A novel formulation and column generation approach

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,…

Seminar: Bernardo Pagnoncelli, Monday, October, 4th 2021 -Contextual chance-constrained and risk averse optimization

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…

GOM Seminar: Luigi De Giovanni, Wednesday, January 23rd 2019 – Data-driven approach to the Air Traffic Flow Management problem

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…

OPTIMA Seminar: Émilie Chénier, Monday, July 16th 2018 – Aggregation of a large number of loads under uncertainty of the availability of resources

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…

GOM Seminar: Hande Yaman, Tuesday, March 27th 2018 – Hub Location Problems: Applications, Models and Solution Methods

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…
