Integrating Physician and Clinic Scheduling in Ambulatory Polyclinics

This paper presents an integrated physician and clinic scheduling problem arising in ambulatory cancer treatment polyclinics, where patients may be assessed by multiple physicians from different clinics in a single visit. The problem focuses on assigning clinic sessions and their associated physicians to shifts in a finite planning horizon. The complexity of this problem stems from the fact that several interdisciplinary clinics need to be clustered together, sharing limited resources. The problem is formulated as a multiobjective optimization problem. Given the inherent complexity for optimally solving this problem with a standard optimization software, we develop a hybrid algorithm based on iterated local search and variable neighborhood decent methods to obtain high quality solutions. Computational results using a set of instances inspired from a case study in a hospital in Canada along with some managerial insights are reported and analyzed.
