Geometry-based Constraint Generation for Large-scale Radiation Therapy Treatment Planning
(University of Waterloo, 2019-12-17)Intensity-Modulated Radiation Therapy (IMRT) is a high precision radiotherapy with many beams that have different intensities to accurately irradiate a tumor/cancerous cells considering minimization of the dose to surrounding ... -
Radiotherapy Patient Scheduling During Pandemics
(University of Waterloo, 2022-09-26)With the Covid-19 outbreak happening worldwide, clinically vulnerable people should be of concern, as they are more likely to be exposed to the virus. Cancer patients with weak immune systems are a group of aforementioned ... -
Reducing Conservatism in Pareto Robust Optimization
(University of Waterloo, 2022-06-09)Robust optimization (RO) is a sub-field of optimization theory with set-based uncertainty. A criticism of this field is that it determines optimal decisions for only the worst-case realizations of uncertainty. Several ... -
Robust Direct Aperture Optimization Methods for Cardiac Sparing in Left-Sided Breast Cancer Radiation Therapy
(University of Waterloo, 2018-09-26)Designing conformal and equipment-compatible radiation therapy plans is essential for ensuring high-quality treatment outcomes for cancer patients. Intensity modulated radiation therapy (IMRT) is a commonly-used method of ... -
Robust Multi-Class Multi-Period Scheduling of MRI Services with Wait Time Targets
(University of Waterloo, 2018-01-23)In recent years, long wait times for healthcare services have become a challenge in most healthcare delivery systems in Canada. This issue becomes even more important when there are priorities in patients' treatment which ... -
A Robust Optimization Approach for Advance Scheduling in Health Care Systems with Demand Uncertainty: Policy Insights
(University of Waterloo, 2021-02-17)Patient wait times have increased significantly over the past few decades. According to the Canadian Institute for Health Information (CIHI), 40% of Canadians have experienced difficulties in receiving diagnostics tests. ... -
Robust Optimization for SCED in AC-HVDC Power Systems
(University of Waterloo, 2019-05-15)Wind power is a clean, renewable and low-carbon resource for power generation that has received increasing attention in power systems over the last few decades. There are two main challenges associated with the large-scale ...
