Scheduling with uncertainty or how to create good schedules without knowing the probability distribution, by Alexander Kononov, Novosibirsk State University and Sobolev Institute of Mathematics, Novosibirsk We discuss new directions in scheduling with uncertainty such as explorable uncertainty, scheduling with testing, query-based approach, resiliency optimization, and untrusted prediction. A generic exact solver for vehicle routing problems ans its applications, by Ruslan Sadykov, Inria Bordeaux and Mathematics Institute of Bordeaux We propose a Branch-Cut-and-Price (BCP) solver for a generic model that encompasses a wide class of vehicle routing problems (VRPs), including some classic variants.

Design of Reverse Supply Chains in the context of the development of circular economy, by Zoé Krug, ISAE-SUPAERO, Toulouse In order to respond to current environmental, economic and social challenges, many institutional actors promote the design of Reverse Supply Chains (RSC). These ones particularly allow to minimize waste and maximize savings in raw materials. Two main difficulties appear when designing such systems. The first one is the presence of many factors of uncertainty in the decision making process. [Read More]

Decomposition-based approaches for a class of two-stage robust binary optimization problems, by Boris Detienne, Associate Prof. at Bordeaux University In this talk, we study a class of two-stage robust binary optimization problems with polyhedral uncertainty set where recourse decisions are restricted to be mixed-binary and uncertainty is present only in the objective function. We present a deterministic equivalent formulation for these problems through convexification of the recourse feasible region. [Read More]
