Capacity, flexibility and pricing decisions for substitutable products under demand and supply uncertainties
(2017-05)
We study the resource investment and pricing decisions for a profit-maximizing firm producing two substitutable products with partially flexible resources facing three types of uncertainties separately: demand uncertainties, ...
Nonlinear stochastic dynamic systems approach for personalized prognostics of cardiorespiratory disorders
(2013-07)
This research investigates an approach rooted in nonlinear stochastic dynamic systems principles for personalized prognostics of cardiorespiratory disorders in the emerging point-of-care (POC) treatment contexts. Such an ...
Enterprise Architecture Framework of a Lean enterprise transformation
(2014-05)
Today's business environment is characterized by fast changes, uncertainty, variability, and unpredictability. To be more competitive, firms have to improve their operations performance. To achieve this, one path is to ...
Backup capacity coordination between renewable and conventional power suppliers under renewable portfolio standard regulation
(2015-05)
This dissertation studies the impacts of renewable portfolio standard (RPS) regulation on regional electricity markets, and the backup capacity coordination mechanisms between renewable and conventional power suppliers ...
Decomposition algorithms for detecting low-diameter clusters in graphs
(2016-05)
Detecting low-diameter clusters in graphs is an effective graph-based data mining technique, which has been used to find cohesive subgraphs in a variety of graph models of data. Low pairwise distances within a cluster can ...
Statistical models for detecting existence of obstructive sleep apnea, predicting its severity, and forecasting future episodes
(2015-12)
This dissertation presents three statistical models based on data mining and nonlinear time-series analysis techniques as an alternative method for the diagnosis and treatment of obstructive sleep apnea disease (OSA). From ...
Sensor-based nonlinear and nonstationary dynamic analysis of online structural health monitoring
(2013-12)
This dissertation focuses on robust online Structural Health Monitoring (SHM) framework for civil engineering structures. The proposed framework improves the diagnostic and prognostic schemes for damage-state awareness and ...
Determining inventory base stock levels of expendable spare parts under service level agreement for on-time delivery
(2015-05)
Availability of service parts is critical to have adequate equipment maintenance in order to avoid costs associated with unplanned shut downs, loss of production, and increase safety among others. Determining an adequate ...
Supply chain coordination under advance-purchase discount contract with sales effort and transshipment
(2017-12)
In today's business environment, a competition is no longer about competing between firms, but between supply chains. Improving supply chain's performance has become necessary for companies to survive. Supply chain ...
Forecasting for nonlinear and nonstationary systems using intrinsic functional decomposition models
(2014-12)
The purpose of this study is to develop nonlinear and nonstationary time series forecasting methods to address modeling and prediction of real-world, complex systems. Particular emphasis has been placed on nonlinear and ...
