ORAHS International Seminar Series

Welcome to the ORAHS International Seminar Series!

Our next seminar on OR applied to Health Services is scheduled for December 6th.

The ORAHS International Seminar Series aims to provide state-of-the-art research talks for scholars worldwide who are active in the nexus of OR/OM and healthcare applications. We believe these seminars will prepare and support graduate students and researchers who are active in the field with the newest research conducted worldwide. Moreover, they provide opportunities for academic members to get acquainted and find possible future collaborations.

How to join?

The seminars are planned monthly, every last Tuesday of the month (except November/December 2022), via Zoom in the late afternoon (Europe), morning (US), or evening (Asia/Pacific).

Upcoming SEMinars

December 6th, 16:00-17:00 CEST - Dynamic assignment of capacity and fair balancing of COVID-19 patients over hospitals - Prof. Richard Boucherie

Abstract: We introduce models that support dynamic fair balancing of COVID-19 patients over hospitals in a region and across regions.

Patient flow is captured in an infinite server queueing network. Input for the model is an accurate real-time forecast of the number of COVID-19 patients hospitalised in the ward and the Intensive Care Unit of the hospitals based on the predicted inflow of patients, their Length of Stay and patient transfer probabilities among ward and ICU.

For given number of available beds, we introduce a dynamic load balancing model for assignment of patients to hospitals within a region, and a stochastic program for allocation of patients across regions. Subsequently, we consider optimal up- and downscaling of capacity for COVID-19 patients leaving maximum capacity for regular (non-COVID) patients.

We illustrate our models using data from the second COVID-19 peak from hospitals' data warehouses and regional infection data as recorded in the Netherlands.

Bio: Prof. Richard Boucherie is a full professor in the Center for Healthcare Operations Improvement and Research of the University of Twente (NL). More information about Prof. Boucherie will follow soon.

Registration: Please register now for the seminar on December 6th.
