    • Robust inverse optimization 

      Ghobadi, Kimia; Lee, Taewoo; Mahmoudzadeh, Houra; Terekhov, Daria (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 ...

      Mirahmadi Shalamzari, Akram (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 

      Niazi Shahraki, Nafise (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 

      Landry, Jason Conrad (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 

      Lu, Da (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 ...
    • Robust Optimization for SCED in AC-HVDC Power Systems 

      Dehghani Filabadi, Milad (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 ...
    • The Role of Affect in Commercializing New Ideas 

      Adomdza, Gordon Kwesi (University of Waterloo, 2008-07-22)
      Psychological attachment to an entrepreneurial opportunity may motivate the entrepreneur to persevere but can also bias decisions made in the entrepreneurial process, especially on market entry. This thesis investigates ...
    • Role of Category Structure in Human Information Processing 

      Sempson, Stephen (University of Waterloo, 2007-01-19)
      This investigation will use this ability in a different way. Studies have shown that a category can create a grade structure of prototypical items. We will take a graded structure generated by a category, and see if we can ...
    • The Role of Impression Management in Goal Setting 

      Chin, Weiman Raymond (University of Waterloo, 2006)
      This paper examines the effect of impression management on goal level and commitment to the goal. Participants involved in a goal-setting program in the United States were asked to complete a web survey regarding their ...
    • A Semidefinite Programming Model for the Facility Layout Problem 

      Adams, Elspeth (University of Waterloo, 2010-08-30)
      The continuous facility layout problem consists of arranging a set of facilities so that no pair overlaps and the total sum of the pairwise connection costs (proportional to the center-to-center rectilinear distance) is ...
    • Sequential Decision Making Schemes in Inventory and Transportation Environments 

      Coulombe, Marc (University of Waterloo, 2013-01-10)
      Many mathematical models exist for the simultaneous optimization of transportation and inventory functions. A simultaneous model, while giving the lowest total cost, may not be easily implemented in a firm with decentralized ...
    • Service System Design with Immobile Servers, Stochastic Demand and Economies of Scale 

      Wang, Yan (University of Waterloo, 2015-05-26)
      The service system design problem seeks to locate facilities, determine their capacity, and assign customers to them in order to improve the service quality and the customers' experience while minimizing the capacity ...
    • Shared Community Energy Storage Allocation and Optimization 

      Chang, Hsiu-Chuan (University of Waterloo, 2019-05-13)
      Distributed Energy Resources (DERs) have been playing an increasingly important role for managing households energy costs. DERs consist primarily of energy generation and storage systems utilized by individual households ...
    • Shipment Consolidation in Discrete Time and Discrete Quantity: Matrix-Analytic Methods 

      Cai, Qishu (University of Waterloo, 2011-08-30)
      Shipment consolidation is a logistics strategy whereby many small shipments are combined into a few larger loads. The economies of scale achieved by shipment consolidation help in reducing the transportation costs and ...
    • Shipment consolidation with two demand classes: Rationing the dispatch capacity 

      Satir, Benhur; Erenay, Fatih S.; Bookbinder, James H. (Elsevier, 2018-10-01)
      We analyze the problem faced by a logistics provider that dispatches shipment orders (parcels or larger packages) of two order classes, viz. expedited and regular. Shipment orders arrive according to a compound Poisson ...
    • Shipment Scheduling In Hub Location Problems 

      Masaeli, Mobina (University of Waterloo, 2017-07-26)
      In this thesis, we incorporate shipment scheduling decisions into hub location problems. Our aim is to determine optimal locations of hubs, hub network structure, and the number of vehicles to operate on the hub network ...
    • Should you clean your solar panels now? 

      Gao, Xiang (University of Waterloo, 2014-07-29)
      Photovoltaic (PV) applications worldwide are being increasingly deployed; however, the performance of PV systems is greatly affected by external factors, such as weather, environment, and terrain. These factors can form ...
    • A Simulation Analysis of an Emergency Department Fast Track System 

      La, Jennifer (University of Waterloo, 2011-01-10)
      The basis for this thesis involved a four month Accelerate Canada internship at the Grand River Hospital Emergency Department in Kitchener, Ontario. The Emergency Department (ED) Process Committee sought insight into ...
