Titulo de la Presentación: Retail location and multi-stop trips.

Resumen: Facility location techniques aim at finding the best locations of one or more facilities that serve a demand. In usual facility location problems, users travel to a facility, receive a service or good and go back to their origin. A simple observation of the real world, however, shows that a significant proportion of shopping trips include purchasing more than one product and stopping in more than one place (multipurpose shopping, comparison shopping). This type of trips, addressed only in a handful of papers so far, is what we address in this talk. In these trips, the agents are two retailers and a set of customers. The retailers locate their stores sequentially and consumers choose at which stores to make purchases. We describe and solve the follower problem in this von Stackelberg game, in which the second entrant maximizes its market, while consumers maximize their utilities. An adequate description of the customers’ behavior is vital to understand how these agents make their moves. Computational experience and insights are provided.

Titulo de la Presentación: En transporte urbano, sin operario no hay viaje: minimizar el impacto del ausentismo. 

Resumen: El ausentismo de los operarios en los países en desarrollo es alto: bajos salarios, rotación de trabajos y cuestiones culturales. ¿Cómo asignar los operarios y los vehículos a los viajes previstos por una empresa de transporte urbano sabiendo que varios operarios no son confiables? En tiempos de Covid-19, ¿cuáles viajes debe cubrir una empresa de transporte urbano si varios operarios no pueden presentarse?
