Supply Chain Student Biases Regarding Transportation Jobs, Drew Mahosky

Information Systems Undergraduate Honors Theses

As a Supply Chain student at the University of Arkansas, I have made some observations about how students view jobs with a transportation focus. I have seen other students gravitate towards jobs on the consumer-side of the supply chain job market, with many joining large companies like Walmart and Amazon. The university itself has helped instill this feeling in me as well, due to their focus more on the consumer-side of supply chains. There have only been two classes offered to me thus far in my degree plan that I felt truly addressed transportation-side supply chains at all, with them …

Simulation Modeling Of Cross-Dock And Distribution Center Based Supply Chains, Ghewa Al Chall

Graduate Theses and Dissertations

Companies are implementing new strategies to meet the customer requirements in terms of quality, timing, and cost. One of these strategies is cross-docking, which can be defined as the process of consolidating the products coming from different suppliers, but having the same destination, with minimal handling and almost no storage between loading and unloading of the goods. The purpose of this research is to investigate the benefits of having a cross-docking facility in a supply chain. In this research, we focus on developing discrete event simulation models using the opensource Java Simulation Library (JSL). Also, we work on augmenting an …

The Dynamics And Effects Of Supply Network Structure, Marat Davletshin

Graduate Theses and Dissertations

The rising interest in network theory among supply chain scholars reflects an emerging shift in perspective. To deliver global speed, efficiency, and responsiveness, modern firms’ supply chains are becoming increasingly complex. The patterns of interactions and interdependencies among hundreds of firms interconnected by these complex supply chains cannot be adequately explored from the dyadic perspective, which has dominated supply chain research for decades. Many supply chain scholars agree that the language of networks can provide a syntax and structure to describe and explore this complex reality. The actual application of network theory in supply chain research, however, has been limited. …

Markets And Supply Chains: An Investigation Of The Institutions Influencing The Farm-Supply Chain Interface, Jessica L. Darby

Graduate Theses and Dissertations

Farm-level operations have lasting and amplified impacts that promulgate the entire supply chain, and the farm is increasingly in the forefront of today’s headlines on topics such as social responsibility, environmental sustainability, traceability, and food safety. Despite its significance, however, the farm remains a ‘black box’ and has traditionally operated independently with little information-sharing, trust, or collaboration with buyers downstream. This dissertation begins to unpack this ‘black box’ by employing different methodologies to identify the factors influencing exchange in the farm-supply chain interface. In Essay 1, I examine why the farm continues to be a challenge for ‘traditional’ collaborative approaches …

Extending The Boundaries Of Supply Chain Transparency: Supplier Monitoring Activity Disclosure, Consumer Evaluations, And Brand Equity, Yanji Duan

Graduate Theses and Dissertations

Socially responsible policy makers and consumers are pressuring firms to make their supply chains more transparent by disclosing information about their supplier monitoring activities (SMA). Yet, high monitoring costs and the complexity of supply chains pose challenges for firms to effectively monitor their extended supply chain, including both first-tier and lower-tier suppliers. In order to comprehensively evaluate the net benefit from SMA, it is therefore critical to consider potential effects on drivers of additional revenues that may accrue from the disclosure of SMA to consumers.

Prior research on SMA has examined the associated cost, risk, and supplier relational implications on …

Comprehensive Poultry Supply Chain Model With Vertical And Horizontal Linkages: Implication Of Domestic And International Shocks, Hakan Unveren

Graduate Theses and Dissertations

A Meticulous Food Safety Plan Today Avoids Handcuffs Tomorrow, Kim Bousquet

Journal of Food Law & Policy

In August 2010, thousands of people across the United States were poisoned by eating eggs unknowingly tainted with Salmonella enteritidis bacteria. Following a lengthy investigation, the owners of the facility where the outbreak began were sentenced to three months in prison. This is not a one-off case; poor food safety practices are responsible for several outbreaks and often end in incarceration. Filthy hen houses, diseased fruit storage, and negligent food processing may be the last thing we want to imagine, but these practices have much to teach today's food producers. This article first examines how poor food production practices can …

Classifying Interdependencies In The Food And Agriculture Critical Infrastructure Sector, John Doerpinghaus

Graduate Theses and Dissertations

This work classifies examples of infrastructure interdependencies found in the food and agriculture critical infrastructure sector. Interdependencies are identified through an examination of rice and poultry agriculture throughout the state of Arkansas. The subtleties of interdependence examples in the food and agriculture sector are inadequately captured by the well-studied interdependence classification taxonomies. Through 39 interviews, we develop an understanding of the subtle temporal, geographic, and productivity scales of interdependence in over 100 examples and present five new, distinct classifications of interdependence: (1) dynamic physical, (2) dynamic geographic, (3) deadline, (4) delay, and (5) human, economic, and natural resource interdependencies.

Retaining Valued Human Capital: Investigating The Demand Side Of The Labor Market, Dorothea Roumpi

Graduate Theses and Dissertations

According to the Resource Based View, human capital resources are the key for sustainable competitive advantage. Human capital, however, is not an organizational possession and the voluntary turnover of valued human capital can erode an organization’s competitive advantage. In particular, subsequent losses in productivity and enabling rival firms to gain competitive advantage are only a few of the consequences of voluntary turnover.

The question of how organizations can influence turnover has triggered numerous conceptual and empirical papers. The majority of such endeavors focus on supply-side mobility constraints, exploring what organizations can do in order to minimize turnover intentions. On the …

The Contagion Of Lean Inventory Management In The Supply Chain, Kennedy Green

Supply Chain Management Undergraduate Honors Theses

This study examines the impact of buyer-supplier relationship age and industry similarity on the effect of buyer inventory leanness on supplier inventory leanness. While previous literature has studied the relationship between buyer inventory leanness and supplier inventory leanness, there has not been a large focus on the external relationship characteristics that influence this relationship. This study hypothesizes that buyer-supplier relationship age and similarity increase the effect of buyer inventory leanness on supplier inventory leanness. With data from buyer-supplier observations in different U.S. industries from 2008 to 2015, regression was used to measure the inventory leanness of each supplier and year. …

Is It We Or They? The Effect Of Identity On Collaboration And Performance In Buyer-Supplier Relationships, Siqi Ma

Graduate Theses and Dissertations

In today’s scale-driven and technology-intensive global economy, collaboration becomes the supply chain’s core capability (Liker and Choi, 2004). A well-developed ability to create and sustain fruitful collaborations gives companies a significant competitive advantage (Kanter, 1994). Retailers are increasingly relying on their suppliers to reduce costs, improve quality, and develop new processes and products faster than their rivals’ vendors can. On the other hand, suppliers benefit from retailers that they are able to monitor store-level demand in real time in order to ensure the top-selling items are in-stock or the accuracy and timeliness of retailer’s demand forecast. Previous literature has shown …
