Decision-making problems are ubiquitous in industry, from production optimization to in-service product operation management, including internal project and resource optimization.

In the last decades, many data-driven (e.g. Deep Reinforcement Learning) and model-based (e.g. AI Planning, Constraint Programming) approaches have been separately investigated to solve those problems.

While the former often need a huge amount of data which is scarcely available in many industrial problems, the latter are not always suitable for problems that are complex to model with accuracy.
 

Also, both approaches fail to solve large problems in reasonable time and computational resources, especially in presence of uncertainty that significantly augments the combinatorial explosion of the solution space.

Cette chaire étudiera les techniques d’hybridation étroite entre les approches décisionnelles basées sur les données et celles basées sur les modèles en ciblant trois objectifs principaux : l’extensibilité, la robustesse et la représentativité des cas d’utilisation industriels.

It strives for opening the door to optimized, reactive and robust decision-making in large and complex industrial problem scenarios, while significantly lowering the computation and data cost of current solvers used in the industry

The chair will gather together academic researchers from diverse institutions (LAAS, IRIT, IRT, ONERA, Ottawa University) and scientific fields, including combinatorial ptimization, search, and machine learning.

Co-chairs

Industrial partners from the aerospace and automotive industries (Airbus, Liebherr, Vitesco) will second engineers and provide challenging use cases where hybrid methods are expected to reduce operational costs due to uncertainty, model inaccuracy or solution suboptimality. This research will also benefit the health sector where we will investigate with Oncopole how to optimally schedule radiotherapy treatments for cancer patients under uncertain medical pathway appointments, with a view to improving remission chances.
