Fleet and crew scheduling with profitability increase and staff satisfaction

 

Authors Ana Wemans and Ricardo Saldanha present the following papers at the CASPT event:

  • "Profit-based Optimization of Rolling Stock Rotations: a case study from North America", co-authored by Ricardo L. Saldanha, and Rita Portugal. This paper addresses a fleet optimization problem that is relevant for train operations with reserved seats. Because practical problem instances cannot be solved exactly the authors propose an approximate solution method that combines existing techniques in a new way. By using this approach in production environment VIA Rail Canada obtained significant revenue growths and cost savings. They also reported optimiality gaps for small problem instances. | Download full paper here.

 

  • "Crew Rostering with Fair Satisfaction of Personal Preferences" co-authored by Ana Wemans, Jorge Roussado, and Ricardo L. Saldanha. The paper is about the personalized crew rostering problem in a context where each employee has his own skills, seniority and preferences, where all work has to be assigned and optimization goals include maximising preference satisfaction and fairness. SISCOG authors propose an approach that combines operational research with auction theory for addressing scenarios where employees may prefer different things and seniority may not be strict, which have not yet been addressed. They evaluate the approach with real world data. | Download full paper here.
