An Information Theoretic Investigation Of Complex Adaptive Supply Networks With Organizational Topologies, Joshua V. Rodewald
An Information Theoretic Investigation Of Complex Adaptive Supply Networks With Organizational Topologies, Joshua V. Rodewald
Theses and Dissertations
Supply networks exist throughout society in manufacturing and knowledge-intensive industries as well as many service industries. Organizations have been noted to behave as complex adaptive systems or information supply networks with both formal and informal structures. Thoroughly understanding supply network structure and behavior are critical to managing such organizations effectively, but their properties of complex adaptive systems make them more difficult to analyze and assess, forcing researchers to rely on unrealistic data or assumptions of behavior. This research proposes an information theoretic methodology to discover such complex network structures and dynamics while overcoming the difficulties historically associated with their study. …
A Neural Network For Collaborative Forecasting, Abdulrahman M. Enani
A Neural Network For Collaborative Forecasting, Abdulrahman M. Enani
Masters Theses
As the supply chain activities’ backbone, demand forecasting must be accurate. This paper proposes an artificial neural network forecasting model, which integrates and synchronizes shared information, such as sales or consumption rate among different partners, to improve the forecasting’s accuracy. This information sharing is part of the collaborative planning, forecasting and replenishment (CPFR) model, which is a supply chain model aiming to enhance the supply chain’s efficiency by jointly planning and forecasting between two or more supply chain partners that will be used as the base for production and replenishment activities. The model is validated using a tuna product sales …
Service Improvement And Cost Reduction For Airlines: Optimal Policies For Managing Arrival And Departure Operations Under Uncertainty, Heng Chen
Doctoral Dissertations
Annual U.S. air travel demand has been growing steadily by 4-5% over the last decade, and it is estimated that the demand will nearly double in the next twenty years. It has also been estimated by the International Civil Aviation Organization that global demand for commercial aircraft will increase at an average annual rate of 4.1% by 2034 (IATA, 2014). However, airport expansions and aviation infrastructure upgrades have not kept pace with the increase in air traffic demand, as only 3% of all the new airport projects around the world are planned in the U.S. (CAPA, 2015). Thus, the operation …
Network Game Theory Models Of Services And Quality Competition With Applications To Future Internet Architectures And Supply Chains, Sara Saberi
Doctoral Dissertations
The Internet has transformed the way in which we conduct business and perform economic and financial transactions. One key challenge of the Internet is the inefficiency of the mechanisms by which technology is deployed and the business and economic models surrounding these processes (Wolf et al. (2014)). Equilibrium models for the Internet generally assume basic economic relationships. However, in new paradigms for the Internet and in supply chain networks, price is not the only factor; quality of service (QoS) is also of increasing importance. Supply chains networks, which give us the means to manufacture products and deliver them to points …

Improving The Nuclear Reform Implementation For Success, Allen Y. Agnes
Theses and Dissertations
This research identifies the method used for successful implementations. This method is critical to the nuclear enterprise as it will continually guide the program. Post-Cold War began an era of decline in the nuclear enterprise. Leaders were risk-averse in fear of being fired for making mistakes, the nuclear culture lost its experts, organizations were drawn to the conventional fight, and training lacked the priority necessary to rebuild the nuclear enterprise. In 2007 and 2008 two major incidents occurred, a necessary to bring focus and priority back to the nuclear enterprise. Several reports were accomplished to identify the issues and recommendations. …
The Influence Of Education And Experience Upon Contextual And Task Performance In Warehouse Operations, Allen R. Miller
The Influence Of Education And Experience Upon Contextual And Task Performance In Warehouse Operations, Allen R. Miller
Theses and Dissertations
Supply chain workers make observable, preventable errors while completing their assigned tasks in the shipping process. Previous research has indicated that individuals with a greater grasp of their work and better system knowledge are less likely to commit interpretation errors. We believe worker-performance may, likewise, be affected by an individuals knowledge of why and where they fit into a larger system defined as mission knowledge. To assess our research objectives, we conduct a controlled experiment with 100 workers in the Air Force supply career field to discern how mission clarity, that is, education, experience and subject characteristics affect pick and …
Procurement Fraud, Lisa Mcnamee
Procurement Fraud, Lisa Mcnamee
Economic Crime Forensics Capstones
The 2016 Global Economic Crime Survey conducted by PricewaterhouseCoopers LLP (2016), states that twenty-two percent of companies have experienced procurement fraud. The statistics have actually decreased since 2014 when twenty-seven percent of companies had experienced procurement fraud. However, procurement fraud is still one of the most costly fraudulent schemes. Despite the reduction, the Department of Defense continues to experience large procurement fraud cases, both in number and dollar value. A recent example is the Supreme Foodservice fraud case, which cost the Defense Logistics Agency $757 million dollars in fraudulent charges. (Jahner, 2014) The Department of Defense Office of Inspector General …
Cross-Functional Integration In The Supply Chain: Construct Development And The Impact Of Workplace Behaviors, Daniel A. Pellathy
Cross-Functional Integration In The Supply Chain: Construct Development And The Impact Of Workplace Behaviors, Daniel A. Pellathy
Doctoral Dissertations
Cross-functional integration (CFI) is central to supply chain theory and practice. However, researchers have yet to settled on a consistent definition or measure of CFI, creating confusion over its conceptual content and making it difficult to validate given operationalizations. In addition, researchers have only recently begun to explore the impact of workplace behaviors on CFI and supply chain performance. The two studies in this dissertation seek to contribute to the supply chain literature in both of these areas. Study 1 develops a comprehensive definition and valid measure of CFI based on a systematic process of construct development. Study 2 employs …
Examining The Nature And Consequences Of Interfunctional Bias In A Corporate Setting, William Adam Powell
Examining The Nature And Consequences Of Interfunctional Bias In A Corporate Setting, William Adam Powell
Doctoral Dissertations
Interfunctional bias is examined in this dissertation as a potential barrier to interfunctional cooperation. Interfunctional cooperation is desirable in modern corporate organizations as a contributor to effective service delivery, operations planning, and sales performance. Interfunctional stereotyping, prejudice, and discrimination are hypothesized to relate positively, and together provide the bias-based theoretical basis through which barriers to interfunctional cooperation can be more thoroughly understood. Based on the extant literature in marketing and psychology, competing models of interfunctional bias are developed and hypothesized. In the first of three studies a questionnaire-based survey of supply chain employees’ perceptions of salespeople permitted the examination of …
Newsvendor Models With Monte Carlo Sampling, Ijeoma W. Ekwegh
Newsvendor Models With Monte Carlo Sampling, Ijeoma W. Ekwegh
Electronic Theses and Dissertations
Newsvendor Models with Monte Carlo Sampling by Ijeoma Winifred Ekwegh The newsvendor model is used in solving inventory problems in which demand is random. In this thesis, we will focus on a method of using Monte Carlo sampling to estimate the order quantity that will either maximizes revenue or minimizes cost given that demand is uncertain. Given data, the Monte Carlo approach will be used in sampling data over scenarios and also estimating the probability density function. A bootstrapping process yields an empirical distribution for the order quantity that will maximize the expected profit. Finally, this method will be used …
Systemic Risk In Financial Networks, Peng-Chu Chen
Systemic Risk In Financial Networks, Peng-Chu Chen
Open Access Dissertations
This thesis extends the literature of systemic risk in financial networks in two directions.
First, we develop a majorization-based tool to compare financial networks in terms of systemic losses with a focus on the implications of liability concentration. Specifically, we quantify liability concentration by applying the majorization order to the liability matrix that captures the interconnectedness of banks in a financial network. We develop notions of balancing and unbalancing networks to bring out the qualitatively different implications of liability concentration on the system's loss profile. An empirical analysis of the network formed by the banking sectors of eight representative European …

The Influence Of The Electric Supply Industry On Economic Growth In Less Developed Countries, Edward Richard Bee
Dissertations
This study measures the impact that electrical outages have on manufacturing production in 135 less developed countries using stochastic frontier analysis and data from World Bank’s Investment Climate surveys. Outages of electricity, for firms with and without backup power sources, are the most frequently cited constraint on manufacturing growth in these surveys.
Outages are shown to reduce output below the production frontier by almost five percent in Africa and by a lower percentage in South Asia, Southeast Asia and the Middle East and North Africa. Production response to outages is quadratic in form. Outages also increase labor cost, reduce exports …
Omni-Channel Supply Chain Management: Assessing The Impact Of Retail Service Operations In The Retail Supply Chain, Simone Theresa Peinkofer
Omni-Channel Supply Chain Management: Assessing The Impact Of Retail Service Operations In The Retail Supply Chain, Simone Theresa Peinkofer
Graduate Theses and Dissertations
The traditional retail environment, which is characterized by a clear division between brick-and-mortar and non-brick-and-mortar retail channels, has been recently disrupted by developments in e-commerce and mobile technologies. The result has been the emergence of omni-channel retailing. Within the reality of this new retail environment, it has been proposed that retailers should develop the necessary capabilities to fulfill consumer demand from anywhere – the store, the distribution center, or via drop-shipping from a supplier – which leads to the emergence of new operational complexities and challenges in the retail supply chain. In light of the growing popularity of these new …

A Simulation Model Of The “Bio-Depot” Concept In The Context Of Components Of Variance And The “Taguchi Loss Function”, Maximilian Platzer
Masters Theses
The research focuses on the simulation, statistical evaluation, costs, and continuous improvement of supply chains for bio-based materials. A significant challenge of using cellulosic feedstocks for biofuel or bioenergy production is the high per unit costs of final products, e.g., biofuels. The goal of the research is to provide practitioners with useful statistical methods and a simulation Excel template for evaluating the variance and costs associated with the supply chain of bio-based products. Statistical Process Control (SPC), components of variance, Taguchi Loss Function, and reliability block diagrams (RBD) are used in this thesis for the evaluation of the supply chain …
From Offshoring To Reshoring: A Conceptual Framework For Manufacturing Location Decisions In A Slow-Steam World, Jeffrey J. Risher
From Offshoring To Reshoring: A Conceptual Framework For Manufacturing Location Decisions In A Slow-Steam World, Jeffrey J. Risher
Doctor of Business Administration Dissertations
Reshoring, the act of moving manufacturing operations from an offshore location to the nation of the parent company, is rapidly becoming one of the most researched topics in business. Reshoring describes the reversal of a previous offshoring decision, whereby a firm either relocated its own manufacturing operations overseas or outsourced a significant portion of production to offshore suppliers. With looming uncertainty in global consumer demand and diminishing returns in offshore markets, reshoring is gaining exposure as a viable strategy for firms experiencing a diluted competitive advantage as grounded costs approach market equilibrium.
With academic literature on reshoring only beginning to …
A Study Of The Impact Of Information Blackouts On The Bullwhip Effect Of A Supply Chain Using Discrete-Event Simulations, Elizabeth Rasnick
A Study Of The Impact Of Information Blackouts On The Bullwhip Effect Of A Supply Chain Using Discrete-Event Simulations, Elizabeth Rasnick
Information Technology & Decision Sciences Theses & Dissertations
This study adds to the supply chain management literature by introducing and investigating information blackouts, sudden and short-duration failure of the information flow. This study aims to contribute to the literature in following ways: first, to define information blackouts in a supply chain. Second, to investigate the response of supply chains to information blackouts using discrete-event simulation. Prior research has focused more on analyzing systemic disruptions to supply chains from well-known sources. We expect the results of this study to be useful to supply chain managers in disaster prone areas.

Two Studies On The Use Of Information Technology In Collaborative Planning, Forecasting & Replenishment (Cpfr), David Mccaw Simmonds
Information Technology & Decision Sciences Theses & Dissertations
In the 1st study, I seek to determine whether there are trends in the coverage of the use of Information Technology in CPFR in support of Supply Chain Management. I look at the way technology is studied along two dimensions. The first dimension is the function within CPFR—Planning, Forecasting or Replenishment. The second dimension is level at which the study addresses use of the technology, whether at the Operational, Tactical or Strategic level. Within this 3x3 matrix, I seek to prove that studies would primarily fall along a line where the higher the level functions should be served by systems …
