Robust inverse optimization
(Elsevier, 2018-05-01)Given an observation of a decision-maker’s uncertain behavior, we develop a robust inverse optimization model for imputing an objective function that is robust against mis-specifications of the behavior. We characterize ... -
Robust Methods for Interval-Censored Life History Data
(University of Waterloo, 2008-08-20)Interval censoring arises frequently in life history data, as individuals are often only observed at a sequence of assessment times. This leads to a situation where we do not know when an event of interest occurs, only ... -
Robust Methods of Testing Long Range
(University of Waterloo, 2007-10-01)This thesis develops a novel robust periodogram method for detecting long memory. Though many test for long memory are based on the idea of linear regression, there exists no results in statistical literature on utilizing ... -
Robust Model for Fatigue Life Estimation from Monotonic Properties Data for Steels
(University of Waterloo, 2013-06-18)Determining the fatigue properties (Manson-Coffin and Ramberg-Osgood parameters) for a steel material requires time consuming and expensive testing. In the early stages of a design process, it is not feasible to perform ... -
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 Neural Network Approach to Optimal Decumulation and Factor Investing in Defined Contribution Pension Plans
(University of Waterloo, 2023-09-18)In this thesis, we propose a novel data-driven neural network (NN) optimization framework for solving an optimal stochastic control problem under stochastic constraints. The NN utilizes customized output layer activation ... -
Robust Nonlinear Model Predictive Control of Biosystems described by Dynamic Metabolic Flux Models
(University of Waterloo, 2019-05-13)The accuracy of the model used for prediction in Nonlinear Model Predictive Controller (NMPC) is one of the main factors affecting the closed loop performance. Since it is impossible to formulate a perfect model for a real ... -
Robust Nonlinear Model Predictive Control using Polynomial Chaos Expansions
(University of Waterloo, 2015-08-13)The performance of model predictive controllers (MPCs) is largely dependent on the accuracy of the model predictions as compared to the actual plant outputs. Irrespective of the model used, first-principles (FP) or empirical, ... -
Robust Optical Engineering for a Trapped Ion Quantum Computer
(University of Waterloo, 2022-09-02)Trapped ions are one of the leading platforms for the implementation of quantum information processing (QIP), exhibiting one of the highest reported quantum gate and measurement fidelities. The challenge for the platform ... -
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. ... -
A Robust Optimization Approach to the Self-scheduling Problem Using Semidefinite Programming
(University of Waterloo, 2010-01-21)In deregulated electricity markets, generating companies submit energy bids which are derived from a self-schedule. In this thesis, we propose an improved semidefinite programming-based model for the self-scheduling problem. ... -
Robust Optimization for Airline Scheduling and Vehicle Routing
(University of Waterloo, 2014-12-03)Robust optimization is an emerging modeling approach to make decisions under uncertainty. It provides an alternative framework to stochastic optimization where operational parameters are random and do not assume any ... -
