This hybrid activity will take place as part of the thematic semester on sustainable mobility. Zoom link
This activity is preceded by "Equity in urban transportation: Gendered travel differences in Canada" et "Bayesian spatiotemporal modeling of passenger trip assignment in metro networks". To participate in this activity, you must register. Coffee will be provided.

In this talk, we study a congested facility location problem in which each facility is modeled as an M/M/c queue. We assume that users are self-interested and choose which facility to patronize so as to minimize their expected total time, defined as the sum of travel time and waiting time. This behavior leads to a bilevel problem in which the upper-level decision maker, the network designer, seeks an effective configuration of facilities, while the lower-level problem corresponds to a user equilibrium model. We propose a flexible single-level reformulation that can accommodate various objectives related to overall system efficiency as well as fairness. The resulting reformulation is a convex mixed-integer nonlinear program that can be solved efficiently.
