Description
Consumer goods supply chains have gradually incorporated lean manufacturing principles to identify and reduce non-value-added activities. Companies implementing lean practices have experienced improvements in cost, quality, and demand responsiveness. However certain elements of these practices, especially those related to transportation and distribution may have detrimental impact on the environment. This study asks: What impact do current best practices in lean logistics and retailing have on environmental performance? The research hypothesis of this dissertation establishes that lean distribution of durable and consumable goods can result in an increased amount of carbon dioxide emissions, leading to climate change and natural resource depletion impacts, while lean retailing operations can reduce carbon emissions. Distribution and retailing phases of the life cycle are characterized in a two-echelon supply chain discrete-event simulation modeled after current operations from leading organizations based in the U.S. Southwest. By conducting an overview of critical sustainability issues and their relationship with consumer products, it is possible to address the environmental implications of lean logistics and retailing operations. Provided the waste reduction nature from lean manufacturing, four lean best practices are examined in detail in order to formulate specific research propositions. These propositions are integrated into an experimental design linking annual carbon dioxide equivalent emissions to: (1) shipment frequency between supply chain partners, (2) proximity between decoupling point of products and final customers, (3) inventory turns at the warehousing level, and (4) degree of supplier integration. All propositions are tested through the use of the simulation model. Results confirmed the four research propositions. Furthermore, they suggest synergy between product shipment frequency among supply chain partners and product management due to lean retailing practices. In addition, the study confirms prior research speculations about the potential carbon intensity from transportation operations subject to lean principles.

Description
This thesis looks at a short-term solution to the truck driver shortage: transitioning U.S. military veterans into truck driver roles. Due to the adoption of self-driving trucks, the shortage is projected to end in 2022; however, freight companies may not be able to keep up with growing freight volumes until then. In the meantime, providing commercial driver's license (CDL) training on military bases has the potential to alleviate the shortage and veteran unemployment. A number of journal articles were read and interviews were conducted to determine the practicality of this solution. This thesis includes those findings and a number of considerations that should be made before implementing it.

Description
The purpose of this honors thesis is to discover ways for a large humanitarian organization to more cost effectively manage its fleet of vehicles. The first phase of work involved cleaning the large data set provided by the organization. Next, we used the program STATA to run a Seemingly Unrelated Regression (SUR) to see which variables have the largest effect on the percentage of price decline and total mileage of each vehicle. The SUR model indicated that price decline is most influenced by cumulative minor repairs, total accessories, age, percentage of paved roads, and number of accidents. In addition, total mileage was most affected by percentage of paved roads, cumulative minor repairs, all wheel drive, and age. The final step of the project involved providing recommendations to the humanitarian organization based on the above results. We recommend several changes to their fleet management, including: driver training programs, increasing the amount of preventative maintenance performed on vehicles, and increasing the amount of accessories purchased for each vehicle. Implementing these changes could potentially save the organization millions of dollars due to the scope of its operation.

Description
This paper will cover topics regarding remote work. More specifically, remote work for the field of logistics. It will also dive into remote work platforms themselves e.g., Slack, Zoom, etc. Microsoft Teams, the specific software we used while I was at my internship, will be analyzed as well. I will, specifically, be analyzing the fundamental issues that occurred during my internship, developing a feasible solution with a laid-out process for each one. After the proper execution of these processes, I will discuss my results. I found that time is the most critical component of an optimal transition to remote work. Finally, I will conclude with reflections on my findings, insights from current working supply chain professionals, and prompt further research that could be done.
