Optimal Planning and Scheduling of Battery Energy Storage Systems for Isolated Microgrids
(University of Waterloo, 2015-05-07)Balancing the energy demand in isolated microgrids is a critical issue especially in the presence of intermittent energy sources. Battery Energy Storage Systems (BESS) can be installed in such circumstances to supply the ... -
Optimal Portfolio Execution Strategies: Uncertainty and Robustness
(University of Waterloo, 2011-10-28)Optimal investment decisions often rely on assumptions about the models and their associated parameter values. Therefore, it is essential to assess suitability of these assumptions and to understand sensitivity of outcomes ... -
Optimal Portfolio Rule: When There is Uncertainty in The Parameter Estimates
(University of Waterloo, 2012-04-11)The classical mean-variance model, proposed by Harry Markowitz in 1952, has been one of the most powerful tools in the field of portfolio optimization. In this model, parameters are estimated by their sample counterparts. ... -
Optimal Portfolio Selection Under the Estimation Risk in Mean Return
(University of Waterloo, 2008-01-17)This thesis investigates robust techniques for mean-variance (MV) portfolio optimization problems under the estimation risk in mean return. We evaluate the performance of the optimal portfolios generated by the min-max ... -
Optimal Power Allocation for a Successive Refinable Source with Multiple Descriptions over a Fading Relay Channel Using Broadcast/Multicast Strategies
(University of Waterloo, 2009-09-29)In a wireless fading relay system with multicast/broadcast transmission, one of the most crucial challenges is the optimization of a transmission rate under multiuser channel diversity. Previously reported solutions for ... -
Optimal Power-Sharing Control for MTDC Systems
(University of Waterloo, 2020-01-27)Power systems have been developing over the past few decades, especially in terms of increasing efficiency and reliability, as well as in meeting the recent rapid growth in demand. Therefore, High Voltage Direct Current ... -
Optimal Processing Pathway for Sludge-to-Energy Technologies: A Superstructure Optimization-Based MINLP Model
(University of Waterloo, 2022-04-27)The perception of sewage sludge has been increasingly changing from being a waste, that is a burden to the environment and society, to a useful resource of materials and renewable energy. There are several available ... -
Optimal Reconfiguration of Complex Production Lines for Profit Maximization via Simulation Modeling
(University of Waterloo, 2014-11-21)With the recent trend of re-shoring, transferring manufacturing systems from a workforce-intensive to a capital-intensive production environment becomes more common. One challenge multinational manufacturing companies may ... -
Optimal Reinsurance Designs: from an Insurer’s Perspective
(University of Waterloo, 2009-09-30)The research on optimal reinsurance design dated back to the 1960’s. For nearly half a century, the quest for optimal reinsurance designs has remained a fascinating subject, drawing significant interests from both academicians ... -
Optimal Reinsurance Retentions under Ruin-Related Optimization Criteria
(University of Waterloo, 2008-12-02)Quota-share and stop-loss/excess-of-loss reinsurances are two important reinsurance strategies. An important question, both in theory and in application, is to determine optimal retentions for these reinsurances. In ... -
Optimal Relay Station Placement in Broadband Wireless Access Networks
(University of Waterloo, 2012-08-31)With the development of IEEE 802.16j multihop relay protocol, the requirement to enhance the network capacity in a wireless network has been met e ectively. In this thesis, we study the capacity enhancement problem for a ... -
