Knowledge Gap: Supply Chain Students And Employers, Kathryn Bules Mar 2019

Knowledge Gap: Supply Chain Students And Employers, Kathryn Bules

Honors Theses

This thesis project aims to identify the gap(s) between supply chain students and employers for both the preparedness and relative importance of the critical job skills employers seek in graduating students. This research is relevant because students view college as an investment that will pay off through better job placement and higher pay upon graduation. The problem is that some employers feel students do not have the skills necessary to be successful on the job. While there has been extensive research regarding a skills gap in graduating students and common criteria employer’s use to rank these students, there is minimal …


Humanitarian Logistics: Shipping Designs For The Post Disaster Cargo Surge, Nicholas L. Green Mar 2019

Humanitarian Logistics: Shipping Designs For The Post Disaster Cargo Surge, Nicholas L. Green

Theses and Dissertations

In 2017 Hurricane Maria devastated Puerto Rico. The humanitarian aid community scrambled a response to support the 3.4 million people affected by the disaster. In response, thousands of shipping containers filled with supplies were sent to the island. Numerous reports surfaced regarding significant delays in receiving the shipments. This research reviews the historical account of cargo throughput into Puerto Rico following Maria. A computer simulation built in ARENA compares various what-if scenarios based on empirically collected data and interviews with FEMA, port authorities, and commercial cargo carriers to determine how the humanitarian supply chain could improve for future disaster planning. …


Applying The Multiple Multidimensional Knapsack Assignment Problem To A Cargo Allocation And Transportation Problem With Stochastic Demand, Jocelin S. Maus Mar 2019

Applying The Multiple Multidimensional Knapsack Assignment Problem To A Cargo Allocation And Transportation Problem With Stochastic Demand, Jocelin S. Maus

Theses and Dissertations

The US military relies on airlift to not only deploy and sustain U.S. armed forces anywhere in the world but also to rapidly mobilize humanitarian efforts and supplies. Operations already impacted by the limited capacity of aircraft also fall prey to dynamic requirements and differing priorities of multiple global locations. A growing concern for the modern military budget is how to provide airlift functions expediently and economically while mitigating the costs of shortfalls and overages. Utilizing fiscal year 2017-2018 cargo data published by the 618th Air Operations Center and modeling this problem as a multiple multidimensional knapsack assignment problem (MMKAP), …


Predicting Failures Of The Brazilian Air Force Tucano Fleet Using Survival Analysis, Luciana Mesquita Monteiro Mar 2019

Predicting Failures Of The Brazilian Air Force Tucano Fleet Using Survival Analysis, Luciana Mesquita Monteiro

Theses and Dissertations

During the life of an aircraft, several failures may occur causing unplanned maintenance and costs of parts, labor, transportation, lost opportunities, and operations, among others. The prediction of these events becomes especially difficult for new airframes, since they do not have many flight hours or enough data to observe failures. This study analyzes and model the time between failures (TBF) of the Brazilian Air Force T-27 Tucano fleet by applying various non-parametric, semi-parametric, and parametric statistical models, to the TBF, such as the descriptive statistics, Kaplan-Meier estimators, Cox proportional hazards models, with or without frailty, and survival regression models, with …


Fuzzy Inference Systems For Risk Appraisal In Military Operational Planning, Curtis B. Nelson Mar 2019

Fuzzy Inference Systems For Risk Appraisal In Military Operational Planning, Curtis B. Nelson

Theses and Dissertations

Advances in computing and mathematical techniques have given rise to increasingly complex models employed in the management of risk across numerous disciplines. While current military doctrine embraces sound practices for identifying, communicating, and mitigating risk, the complex nature of modern operational environments prevents the enumeration of risk factors and consequences necessary to leverage anything beyond rudimentary risk models. Efforts to model military operational risk in quantitative terms are stymied by the interaction of incomplete, inadequate, and unreliable knowledge. Specifically, it is evident that joint and inter-Service literature on risk are inconsistent, ill-defined, and prescribe imprecise approaches to codifying risk. Notably, …


Examining The Express Supportability Module: Implementing An Autoregressive Distributed Lag Approach With Air Force Maintenance Data, Troy J. St Peter Mar 2019

Examining The Express Supportability Module: Implementing An Autoregressive Distributed Lag Approach With Air Force Maintenance Data, Troy J. St Peter

Theses and Dissertations

Launched in 1996, EXPRESS (Execution and Prioritization of Repairs Support System) is a program integral to the Air Force reparable supply chain. Daily, EXPRESS relies on a number of data sources and individual modules like the Supportability Module to determine which necessary repairs can and should be made. The Supportability Module examines the prioritized list of repairs and checks four constraints in order to decide whether each repair can be made given current resources. According to the logic of the module, a single constraint failure means that subsequent resource checks are not made before evaluating the next repair. Unfortunately, this …


Simulating Maritime Chokepoint Disruption In The Global Food Supply, Ryan B. Walton Mar 2019

Simulating Maritime Chokepoint Disruption In The Global Food Supply, Ryan B. Walton

Theses and Dissertations

The three food crops of wheat, maize, and rice make up almost two-thirds of the world's dietary energy needs. Of these three, just six countries provide 70% of the global supply. Furthermore, soybeans account for three-quarters of global livestock feed, and only three countries provide 80% of the global supply. Considering over half of the world's exported supply of these four commodities are exported via maritime means, the free ow of marine traffic becomes paramount. Current models lack the ability to capture the inherent variance displayed in the maritime transport system, which can lead to inaccurate assumptions about how the …


Operations Research Methods For Multi-Domain Campaign Phase Planning, John A. Schlicht Mar 2019

Operations Research Methods For Multi-Domain Campaign Phase Planning, John A. Schlicht

Theses and Dissertations

In "Antiaccess Warfare as Strategy," Tangredi posits the question and need to consider multiple domains and governmental and warfighting functions in various phases of campaign execution. Multi-domain integration within and across various phases of the joint campaign presents a host of non-linear factors that are compounded and amplified by uncertainties. Colonel Blotto is a simple game that is suited to compare traditional force-on-force military engagements where mass wins the day, but have had limited application to more complex military planning. This thesis explores the formulation schema, data-driven parameters, methods of calculation, and scenarios applicable to a generalized Colonel Blotto (General …


Turbojet Range, Loiter, And Altitude Tradeoff Estimations In Efficient Modeling And Optimization Formulations, Lauren M. Bramblett Mar 2019

Turbojet Range, Loiter, And Altitude Tradeoff Estimations In Efficient Modeling And Optimization Formulations, Lauren M. Bramblett

Theses and Dissertations

Identifying accurate tradeoffs between loiter time, range, and loiter altitude for jet aircraft are critical for mission planning, but current methods are cumbersome and time and labor intensive. This research introduces a new method for determining tradeoffs between loiter time, range, and loiter altitude for jet aircraft utilizing specific aircraft performance characteristics and the Bréguet range and endurance equations. Results from this new methodology are compared to the existing model used by the National Air and Space Intelligence Center for flight planning. This method is then extended and applied to several routing assignment problems, taking advantage of the incorporation of …

A New Product Anti-Counterfeiting Blockchain Using A Truly Decentralized Dynamic Consensus Protocol, Naif Alzahrani, Nirupama Bulusu Mar 2019

A New Product Anti-Counterfeiting Blockchain Using A Truly Decentralized Dynamic Consensus Protocol, Naif Alzahrani, Nirupama Bulusu

Computer Science Faculty Publications and Presentations

The growth of counterfeit goods has plagued the international community for decades. Nowadays, the battle against counterfeiting remains a significant challenge. Most of the current anti‐counterfeiting systems are centralized. Motivated by the evolution of blockchain technology, we propose (Block‐Supply), a decentralized anti‐counterfeiting supply chain that exploits NFC and blockchain technologies. This paper also proposes a new truly decentralized consensus protocol that, unlike most of the existing protocols, does not require PoW and randomly employs a different set of different size of validators each time a new block is proposed. Our protocol utilizes a game theoretical model to analyze the risk …

Installed Base Management Versus Selling In Monopolistic And Competitive Environments, Shantanu Bhattacharya, Andreas Robotis, Wassenhove Luk N. V. Van Mar 2019

Installed Base Management Versus Selling In Monopolistic And Competitive Environments, Shantanu Bhattacharya, Andreas Robotis, Wassenhove Luk N. V. Van

Research Collection Lee Kong Chian School Of Business

This paper compares the policy of selling a product to that of installed base management, in which the manufacturer leases the product to consumers, and bundles repair and maintenance services along with the product. We compare the two policies in a monopolistic setting when a firm uses either one of the policies, and when both policies are used by a single firm. We then compare the policies under competition first when two firms use identical products, and when two firms use vertically differentiated products. Our findings indicate that the selling option dominates the installed base option in a monopolistic environment, …


Corn, Soybeans Or Fallow: Dynamic Farmland Allocation Under Uncertainty, Onur Boyabatli, Javad Nasiry, Yangfang (Helen) Zhou Mar 2019

Corn, Soybeans Or Fallow: Dynamic Farmland Allocation Under Uncertainty, Onur Boyabatli, Javad Nasiry, Yangfang (Helen) Zhou

Research Collection Lee Kong Chian School Of Business

This chapter develops a theoretical basis for understanding the trade-offs facing a farmer for allocating his farmland among several crops over multiple growing seasons. Specifically, we focus on the farmland allocation among two cash crops (corn and soybeans) and letting the farmland lay fallow to rejuvenate the soil and increase the revenue for the crop grown on this farmland in the subsequent seasons. In each growing period, the farmer chooses the allocation in the presence of revenue uncertainty for each cash crop, and crop rotation benefits across periods, where revenue is stochastically larger and farming cost is lower when a …


Selling Off-Grid Light To Liquidity Constrained Consumers, Bhavani Shanker Uppari, Ioana Popescu, Serguei Netessine Mar 2019

Selling Off-Grid Light To Liquidity Constrained Consumers, Bhavani Shanker Uppari, Ioana Popescu, Serguei Netessine

Research Collection Lee Kong Chian School Of Business

Problem definition: A large proportion of the world’s population has no access to electricity and so relies on noxious kerosene for their lighting needs. Solar-based solutions require a large up-front investment and are often unaffordable in this market owing to consumers’ tight liquidity constraints. As an alternative, there are business models relying on rechargeable light bulbs that are sold at a subsidized price (which renders them affordable) and require regular micropayments for recharges (which eases liquidity constraints). These bulbs provide a cheaper and healthier light source than kerosene, yet their adoption is lower than expected, and some consumers continue …


Encouraging Help Across Projects, Pascale Crama, Fabian J. Sting, Yaozhong Wu Mar 2019

Encouraging Help Across Projects, Pascale Crama, Fabian J. Sting, Yaozhong Wu

Research Collection Lee Kong Chian School Of Business

Companies struggle with timely project execution despite employing sophisticated management methods. Although help across projects is critical for time performance, it has not been explicitly incorporated into project management (PM) systems. We model a PM system, based on an innovative real-life practice, that both incorporates and shapes project managers’ helping behavior. A help process is at the core of this system, in which project managers may ask for and provide help while top management facilitates such exchanges. We find that companies should take a nuanced approach when designing help exchange and time-based incentives in tandem. A company that faces high …

Risk Pooling, Supply Chain Hierarchy, And Analysts' Forecasts, Nan Hu, Jian-Yu Ke, Ling Liu, Yue Zhang Feb 2019

Risk Pooling, Supply Chain Hierarchy, And Analysts' Forecasts, Nan Hu, Jian-Yu Ke, Ling Liu, Yue Zhang

Research Collection School Of Computing and Information Systems

We investigate whether a firm's risk pooling affects its analysts' forecasts, specifically in terms of forecast accuracy and their use of public vs. private information, and how risk pooling interacts with a firm's position in the supply chain to affect analysts' forecasts. We use a social network analysis method to operationalize risk pooling and supply chain hierarchy, and find that risk pooling significantly reduces analysts' forecast errors and increases (decreases) their use of public (private) information. We also find that the positive (negative) relationships between risk pooling and analyst forecast accuracy and analysts' use of public (private) information are more …


Becoming A Supplier: Leading Practices For Corporate Buy-In, Elissa Gibbs Feb 2019

Becoming A Supplier: Leading Practices For Corporate Buy-In, Elissa Gibbs

Institute for Veterans and Military Families

Large companies understand the value of having a diverse supplier base that aligns with their diverse customer base. This creates opportunities for veteran-owned businesses (VOBs) as many larger companies are looking for VOBs to bring on as suppliers. Surprisingly, the biggest challenge that many of these companies face is identifying VOBs that fit a certain geographic or business need and have the ability to perform the work required. This resource is helpful for a general understanding of the veteran entrepreneurship industry.

Improving Human Rights Compliance In Supply Chains, Kishanthi Parella Jan 2019

Improving Human Rights Compliance In Supply Chains, Kishanthi Parella

Scholarly Articles

Corporations try to convince us that they are good global citizens: “brands take stands” by engaging in cause philanthropy; CEOs of prominent corporations tackle a variety of issues; and social values drive marketing strategies for goods and services. But despite this rhetoric, corporations regularly fall short in their conduct. This is especially true in supply chains where a number of human rights abuses frequently occur. One solution is for corporations to engage in meaningful human rights due diligence that involves monitoring human rights, reporting on social and environmental performance, undertaking impact assessments, and consulting with groups whose human rights they …
