Time Definite Hub Location Problem

Hub-and-spoke problems have been widely studied in the literature and as they are more of a strategic problem, little effort has been devoted to incorporating service-related restrictions into them. However, current trends in transportation seek more flexibility and tighter service schedules. In this talk we will discuss the nuances of integrating time constraints into hub-and-spoke systems. Two alternative and efficient formulations for hub network design with strict time restrictions and service levels will be presented. To illustrate our contribution, a case-study inspired from the healthcare network of Québec, Canada, will allow us to show the interest and importance of considering this restriction explicitly in the model.
