Mohammad Sadrani, Alejandro Tirachini, Constantinos Antoniou Abstract This paper focuses on optimizing mixed-fleet bus scheduling (MFBS) with vehicles of different sizes in public transport systems. We develop a novel mixed-integer nonlinear programming (MINLP) model to address the MFBS problem by optimizing vehicle assignment and dispatching programs. The model considers user costs, operator costs, and the... read more →

Patricio Salas, Rodrigo De la Fuente, Sebastián Astroza, Juan Antonio Carrasco Abstract This paper investigates the use of Shapley values-based methods to determine the importance of attributes in discrete choice models, specifically within a Multinomial Logit (MNL) framework. We extend the Shapley decomposition Shorrocks (2013) method from linear models. Additionally, the SHAP method Lundberg and Lee (2017)... read more →
