Condition-based Inspection and Maintenance of Medical Devices
(University of Waterloo, 2017-08-25)Inspection and Maintenance of medical devices are essential for modern health services, but the low availability of devices or unnecessary maintenance can cause major problems. A proper maintenance program can signi ... -
Control Mechanisms in Queueing Systems with Nonlinear Waiting Costs
(University of Waterloo, 2017-08-14)In many queueing systems, customers have been observed to exhibit strategic behavior. Each customer gains a value when receiving a product or getting served and suffers when incurring a delay. We consider a nonlinear ... -
Data-Driven Analytics to Support Scheduling of Multi-Priority Multi-Class Patients with Wait Targets
(University of Waterloo, 2016-08-09)The aim of dynamic scheduling is to efficiently assign available resources to the most suitable patients. The dynamic assignment of multi-class, multi-priority patients over time has long been a challenge, especially for ... -
Dynamic Robust Multi-Class Advance Patient Scheduling
(University of Waterloo, 2022-09-01)In this work, we study an advance patient scheduling problem where patients of different classes have different service times and incur different waiting costs to the system. It is known in the literature that multi-class ... -
The Impact of Information on the Performance of an M/M/1 Queueing System
(University of Waterloo, 2017-01-23)Reviews provided by previous customers contain information, which can be used by new customers. This research examines the impact of the user-generated reviews, on the performance of an M/M/1 queueing system. We assume ... -
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 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. ... -
Staff Scheduling During a Pandemic
(University of Waterloo, 2021-09-30)The year 2019 revealed that some of the policies which have shaped the core structure of many organizations in different industries for a long time, could result in an absolute failure in an unprecedented crisis like the ... -
Stochastic Perishable Inventory Systems: Dual-Balancing and Look-Ahead Approaches
(University of Waterloo, 2016-12-23)We study a single-item, multi-period, stochastic perishable inventory problem under both backlogging and lost-sales circumstances, with and without an order capacity constraint in each period. We first model the ... -
A Tractable Approach To Inverse Optimization Under Euclidean Norm
(University of Waterloo, 2023-09-11)The conventional optimization assumes that the problem and its parameters are known, and it utilizes this information to determine the optimal solution. Inverse optimization works in reverse by determining different ...
