Filipe Cabral

My name is Filipe, I am a fourth-year Ph.D. student in Operations Research at the H. Milton Stewart School of Industrial and Systems Engineering. I am fortunate to be advised by Professor Andy Sun. For applications, I study fleet sizing planning for electrical buses. For methodologies, I study Stochastic Programming, Integer Programming, and Reinforcement Learning. I am particularly interested in applications related to decision-making under uncertainty.

    To meet sustainability goals and regulatory requirements, transit agencies worldwide are planning partial and complete transitions to electric bus fleets. This paper presents the first comprehensive and computationally efficient multi-period optimization framework integrating the key planning decisions necessary to support such electrification initiatives. Our model, formulated as a two-stage integer program with integer subproblems, jointly … Read more

    Electric vehicles (EV) pave a promising way towards low-carbon transportation, but the transition to all EV fleets creates new challenges for the public transportation sector. Despite increasing adoption of electric buses, the main challenges presented by the battery electric bus technology include the lack of charging facilities, the reduced operating capacity per battery charge compared … Read more
