Distributionally Robust Fair Transit Resource Allocation During a Pandemic

Xie, Weijun; Sun, Luying; Witten, Tim - 2021

This paper studies Distributionally robust Fair transit Resource Allocation model (DrFRAM) under Wasserstein ambiguity set to optimize the public transit resource allocation during a pandemic. We show that the proposed DrFRAM is highly nonconvex and nonlinear and is, in general, NP-hard....
