Optimizing Cost And Performance Of Infrastrucure Alternatives At Contingency Bases In A Hub-And-Spoke Network, Kyle J. Rodriguez Mar 2021

Optimizing Cost And Performance Of Infrastrucure Alternatives At Contingency Bases In A Hub-And-Spoke Network, Kyle J. Rodriguez

Theses and Dissertations

Military contingency bases require substantial resources and funding sustain and are often not connected to an infrastructure grid. Infrastructure assets produce the required outputs for sustainment, but are often expensive and inefficient, producing a significant logistical burden. With the increasing near-peer threats of opposing military forces, there is a need for more self-sufficient contingency bases with alternatives that reduce resources usage and the cost of sustainment. Accordingly, the goal of this research is to develop an optimization model capable of selecting infrastructure alternative combinations that minimize the overall resource usage and cost of sustainment at the contingency base level.

Exploring The Efficiency Of Self-Organizing Software Teams With Game Theory, Clay Stevens, Jared Soundy, Hau Chan

School of Computing: Conference and Workshop Papers

Over the last two decades, software development has moved away from centralized, plan-based management toward agile methodologies such as Scrum. Agile methodologies are founded on a shared set of core principles, including self-organizing software development teams. Such teams are promoted as a way to increase both developer productivity and team morale, which is echoed by academic research. However, recent works on agile neglect to consider strategic behavior among developers, particularly during task assignment–one of the primary functions of a self-organizing team. This paper argues that self-organizing software teams could be readily modeled using game theory, providing insight into how agile …

In Their Own Words: Forgotten Women Pilots Of Early Aviation, Fred Erisman Jan 2021

In Their Own Words: Forgotten Women Pilots Of Early Aviation, Fred Erisman

Purdue Studies in Aeronautics and Astronautics

Amelia Earhart’s prominence in American aviation during the 1930s obscures a crucial point: she was but one of a closely knit community of women pilots. Although the women were well known in the profession and widely publicized in the press at the time, they are largely overlooked today. Like Earhart, they wrote extensively about aviation and women’s causes, producing an absorbing record of the life of women fliers during the emergence and peak of the Golden Age of Aviation (1925–1940). Earhart and her contemporaries, however, were only the most recent in a long line of women pilots whose activities reached …
