Luis Ignacio Rizzi, Ángelo Cherubini, Eduardo Koffmann and Paula Fariña Abstract We develop a model to perform a cost–benefit analysis of bus fare subsidies under financial constraints that preclude the purchase of additional buses. Our model considers users’ costs in the provision of bus services and the lack of road pricing... read more →

Anna Wang, José M. Grisolía, Ada H.Y. Ma, Juan de Dios Ortúzar  Abstract Online takeaway platforms provide a convenient access to food and their importance has increased dramatically in the last years. Our research explores if and how food choices via takeaway apps change after individuals are informed about excessive calories, fats, carbohydrates, and salts. Our results... read more →

Héctor López-Ospina, Fernando Manzano-Ramallo, Carlos A. González-Calderón, Diana P. Moreno-Palacio & Paula Penagos  Abstract This research develops an optimization model to quantify and minimize the risk associated with the variability of travel costs in freight tour synthesis (FTS) transportation problems. The model integrates objectives of maximizing trip entropy to generate diverse solutions alongside minimizing costs.... read more →

Camila Balbontín, John D. Nelson, David A. Hensher & Matthew J. Beck  Abstract Universities are major trip attractors and generators in large cities, and they have a significant influence on the transport network particularly in high-density areas. The trips to and from university campuses are made by staff, students, and visitors, with an important... read more →

Matías Villafranca, Felipe Delgado, Mathias Klapp Abstract Unexpected delays while executing aircraft maintenance tasks can result in costly operational disruptions for airlines, including expensive flight delays and overtime. In this study, we address uncertainty in maintenance task processing times by designing a daily and cost-effective aircraft maintenance schedule using two-stage stochastic programming. In the first... read more →

Denis Sauré, Miguel O’Ryan, Juan Pablo Torres, Jorge Pacheco, Patricio Aguilera, Andrea Caro, Leonardo J. Basso, Natalia Trigo, Gonzalo Diaz, Marcel Goic Abstract Background In the latter half of 2023, the northern hemisphere initiated the rollout of nirsevimab immunization strategies for infants, yielding promising early results. As Chile prepared for its 2024 strategy implementation, we retrospectively evaluated the potential cost-saving nature of various immunization strategies. Methods Leveraging... read more →

Cristhian Figueroa-Martínez y Natan Waintrub Resumen El artículo indaga en las formas en que el entorno construido incide en las actividades que ocurren en el espacio público según las perspectivas de las personas que habitan barrios vulnerables de Santiago de Chile. Se busca contribuir con estudios que sugieren que el... read more →
