In this talk, we present a simple efficient algorithm for the dynamic multi-class advance patient scheduling which is a challenging problem due to the high variability in the patient daily arrivals and the high dimensionality of the problem. Specifically, we consider a multi-class advance patient scheduling problem where patients of different classes have different service times and incur different waiting costs to the system. Exploiting patient-level offline data, we develop a distributionally robust model and present a dynamic algorithm to schedule patients upon arrival. To quantify uncertainty in arrivals, we apply a smooth, coherent risk measure that allows us to compute robust solutions against perturbations in the patient arrival process. To examine the performance of the algorithm, we leverage the magnetic resonance imaging data from hospitals in Ontario and show that the dynamic robust model outperforms the dynamic stochastic approach significantly.
