Below is a summary of the seminar to be held by Dr. Sırma Karakaya on Wednesday, September 24, at 4:00 PM.
Bio
Dr. Sırma Karakaya completed her undergraduate studies in Industrial Engineering at Bilkent University, followed by a Master’s at Middle East Technical University and a Ph.D. at Özyeğin University. During her doctoral studies, she worked as a research assistant on both national and international research projects. Following her Ph.D., she continued her academic work at Kühne Logistics University, actively participating in various research projects. Her research focuses on disaster management and the effective, sustainable, and equitable management of healthcare needs arising from disasters. Within this scope, she conducts research on optimization under uncertainty, mathematical modeling and the development of novel solution approaches for large-scale decision-making problems.
Abstract
Disasters often render hemodialysis clinics inoperable, posing significant threats to patients with end-stage kidney disease (ESKD), who rely on regular dialysis treatments (three days per week) for survival. Patients affected by service interruptions in clinics must be swiftly transferred to operational clinics. Developing a coordination mechanism before a disaster can facilitate matching patients with available clinics and prevent treatment disruptions. We introduce the Alliance Network Design Problem, which seeks to proactively form alliances among clinics for coordinated renal relief. These alliances enable resource pooling and pre-assign backup clinics to patients. We formulate a two-stage stochastic mixed integer programming model that sets alliance relationships among clinics and make patient-backup clinic assignments considering uncertainties in post-disaster clinic capacities. A case study of hemodialysis clinics in Istanbul-Türkiye, illustrates the effectiveness of our approach in enhancing disaster preparedness for the ESKD patients. We show the benefits of alliance formations in mitigating the impacts of disasters on dialysis treatment compared to a no-alliance setting. We also provide policy-relevant insights by evaluating additional resilience strategies, including the fortification of clinics in high-risk regions and the strategic deployment of contingency hemodialysis machines in operational clinics to enhance post-disaster capacity.
