Too Agile? - Devops Software Development Challenges In A Military Environment, Burl T. Kenner Iii Jul 2019

Too Agile? - Devops Software Development Challenges In A Military Environment, Burl T. Kenner Iii

Theses and Dissertations

Agile and DevOps software development processes now represent proven, commonly accepted models in commercial industry. For DoD military environments however, empowering teams of software developers and end user operators to build, test and release solutions without direct oversight and management of leadership is a brand new experience. In 2017, a DoD software acquisitions revolution occurred when approval was granted to scrap the former ineffective, cost prohibitive process and initiate the agile DevOps model. After one year since its introduction, this paper may represent the very first look at how well this nontraditional process is working out in a military command …


Improving Cooling Tower Chemistry Control And Cost Savings Through Automation, Ryan Matthew Maxwell Jan 2016

Improving Cooling Tower Chemistry Control And Cost Savings Through Automation, Ryan Matthew Maxwell

Theses and Dissertations

Proper chemistry control of cooling towers reduces corrosion, biological growth, and precipitation of solids. Therefore, improving control can lead to increased equipment life, operating efficiency, and safety. Chemistry of cooling towers is highly dependent on loading, weather, and time. As such, cooling tower chemistry varies day to day and even hour to hour, requiring either continuous controls or large operating bands. Through automation, 24/7 monitoring and control can be achieved, allowing for deliberate operation within tight operating bands. As a direct result of automation water consumption has been reduced by 9.1 million gallons per year, CL-49 use has been reduced …


Life-Cycle Analysis Of A Cement Manufacturing Plant Co-Firing Hazardous Waste In The Usa, Stephen P. Holt Jan 2016

Life-Cycle Analysis Of A Cement Manufacturing Plant Co-Firing Hazardous Waste In The Usa, Stephen P. Holt

Theses and Dissertations

The purpose of this work was to determine the overall environmental impacts associated with the co-firing hazardous waste by burning in a cement kiln to replace the use of coal in the cement manufacturing process. This environmental assessment was conducted using LCA methodology. Understanding the environmental impacts associated with burning hazardous waste in a cement factory could help shape national environmental policy, regulations and the need for site specific human health risk assessments in the environmental regulatory permitting processes. Accordingly, the primary objective of this study was to evaluate the environmental impacts from the hazardous waste burning for energy recovery …


The Application Of Lean Six Sigma To Improve A Business Process: A Study Of The Order Processing Process At An Automobile Manufacturing Facility, Sherrian Francina Ellis Jan 2016

The Application Of Lean Six Sigma To Improve A Business Process: A Study Of The Order Processing Process At An Automobile Manufacturing Facility, Sherrian Francina Ellis

Theses and Dissertations

The objective of this study is to explore the application of Lean Six Sigma to determine root causes of process inefficiency and make recommendations for improving the order processing process at an automobile manufacturing facility. State of the art process quality improvement initiatives Lean, Six Sigma, and Lean Six Sigma are used to explore literature and provide a strong theoretical background for this study. Since the study utilizes both quantitative and qualitative data, the study’s methodological approach is classified as mixed methodology. The study is empirical in nature, and single case study is strategy chosen to complete the study. The …
