Learning on Graphs for Mineral Asset Valuation Under Supply and Demand Uncertainty

no code implementations7 Dec 2022 Yassine Yaakoubi, Hager Radi, Roussos Dimitrakopoulos

Valuing mineral assets is a challenging task that is highly dependent on the supply (geological) uncertainty surrounding resources and reserves, and the uncertainty of demand (commodity prices).

Learning to Schedule Heuristics for the Simultaneous Stochastic Optimization of Mining Complexes

no code implementations25 Feb 2022 Yassine Yaakoubi, Roussos Dimitrakopoulos

By learning from data describing the performance of the heuristics, a problem-specific ordering of heuristics that collectively finds better solutions faster is obtained.

Structured Convolutional Kernel Networks for Airline Crew Scheduling

1 code implementation25 May 2021 Yassine Yaakoubi, François Soumis, Simon Lacoste-Julien

Motivated by the needs from an airline crew scheduling application, we introduce structured convolutional kernel networks (Struct-CKN), which combine CKNs from Mairal et al. (2014) in a structured prediction framework that supports constraints on the outputs.

Machine Learning in Airline Crew Pairing to Construct Initial Clusters for Dynamic Constraint Aggregation

no code implementations30 Sep 2020 Yassine Yaakoubi, François Soumis, Simon Lacoste-Julien

The crew pairing problem (CPP) is generally modelled as a set partitioning problem where the flights have to be partitioned in pairings.

Flight-connection Prediction for Airline Crew Scheduling to Construct Initial Clusters for OR Optimizer

no code implementations26 Sep 2020 Yassine Yaakoubi, François Soumis, Simon Lacoste-Julien

We present a case study of using machine learning classification algorithms to initialize a large-scale commercial solver (GENCOL) based on column generation in the context of the airline crew pairing problem, where small savings of as little as 1% translate to increasing annual revenue by dozens of millions of dollars in a large airline.
