Multivariate Nonnormal Regression Models, Information Complexity, And Genetic Algorithms: A Three Way Hybrid For Intelligent Data Mining, Minhui Liu
Doctoral Dissertations
This dissertation develops a novel computationally feasible intelligent data mining and knowledge discovery technique to select the best subset of predictors in multivariate re- gression (MR) models under the assumption that the random error terms of the model follow a general nonnormal family of distributions. Our approach builds an easy-to-use three way hybrid approach by integrating clever statistical modeling procedures based on the information-theoretic measure of complexity (ICOMP) criterion with genetic algorithm (GA) and multivariate nonnormal regression models with Power Exponential (PE) and fam- ily of elliptically contoured (EC) error distributions. This dissertation is composed of four major parts.

Stochastic Optimization Models For Contingency Allocation In Project Management, Barbara Maria Thibadeau
Stochastic Optimization Models For Contingency Allocation In Project Management, Barbara Maria Thibadeau
Doctoral Dissertations
In many cases, risks that threaten successful project completion can be mitigated (or eliminated) with a proper contingency allocation strategy and exacerbated by an improper one. Yet, despite this importance, there is a dearth of research on the cost contingency allocation problem in academic literature. This thesis looks at the cost contingency allocation problem from two different perspectives and two distinct solutions are introduced: a stochastic linear programming model that addresses a short term strategy and convex-concave utility model that provides a long-term planning solution.
The project manager’s ability to approve random requests for contingency is dependent on several constraints, …
Essays On Quantitative Analysis Of Supply Chain Structures, Contracts And Coordination, Xinjie Shi
Essays On Quantitative Analysis Of Supply Chain Structures, Contracts And Coordination, Xinjie Shi
Doctoral Dissertations
This thesis consists of three separate, but related, essays that deal with the topic of how supply chain structure as well as the use of contracts impact performance of a supply chain. The main focus is the analysis of behavior of indirect-sale supply chains in terms of relative bargaining power and decision rights of the participants. Modeling as Stackelberg games, this thesis explores the existence of Nash equilibriums and the issues surrounding supply chain coordination.
In Essay one, “The Role of Decision Structure in Supply Chain Coordination with Stochastic Demand”, the analysis focuses on how different supply chain structures affect …
