Task Optimization Utilizing Digital Transformation Concepts - Automation Project Execution Via Agile Methodology, Anthony Steven Maiello
Task Optimization Utilizing Digital Transformation Concepts - Automation Project Execution Via Agile Methodology, Anthony Steven Maiello
Theses and Dissertations
Task Optimization via the use of automated process improvements is becoming more widespread as more industries lean into the concepts surrounding digital transformation. This shift also necessitates a complementary adaptation in project management methodologies to support the rapid and ever-changing environment, requirements, and innovations. This thesis examines the effectiveness of Agile methodology in managing digital automation projects, with a specific focus placed on process improvements with systems engineering. It accomplished this by contrasting the original model, designed and derived utilizing traditional project management techniques, with the proposed model which is a direct result of the application of Agile project practices. …
Utilizing The System Engineering Trade Study Analysis Method To Analyze Patient Aeromedical Evacuation, Sara Shaghaghi, Jeremy M. Slagley, Michael E. Miller, Gaiven Varshney
Utilizing The System Engineering Trade Study Analysis Method To Analyze Patient Aeromedical Evacuation, Sara Shaghaghi, Jeremy M. Slagley, Michael E. Miller, Gaiven Varshney
Faculty Publications
The US Air Force has gone through many aeromedical patient isolation transport system designs. The first designs were developed in response to the Ebola outbreak in 2014 and, more recently, the COVID-19 pandemic. The trade study analysis part of the system engineering design method was used to analyze the historic and current aeromedical patient contamination control transport systems. A trade study is a process that evaluates alternatives based upon various “-ilities”, such as reconfigurability, flexibility, durability, cost, and more, and performs a systematic analysis to aid designers in producing a ‘good’ design alternative given the large set of possible solutions. …
Project Management And Systems Engineering Framework For Educational Cubesat Missions, Bailey Garrett
Project Management And Systems Engineering Framework For Educational Cubesat Missions, Bailey Garrett
Master's Theses
The rising complexity of CubeSat missions and the unique challenges faced by educational CubeSat programs lead to high rates of mission failure. Implementing project management and systems engineering practices can alleviate these challenges and improve mission success rates for educational CubeSat developers. However, existing project management and systems engineering resources are too cumbersome and often assume the student has a base-level understanding of project management and systems engineering fundamentals. A new universal project management and systems engineering framework was created and tailored specifically to the needs of an educational CubeSat mission. The framework was designed to accommodate first-time CubeSat developers, …
Testing And Verification For The Open Source Release Of The Horizon Simulation Framewortesting And Verification For The Open Source Release Of The Horizon Simulation Framework, William J. Balfour
Testing And Verification For The Open Source Release Of The Horizon Simulation Framewortesting And Verification For The Open Source Release Of The Horizon Simulation Framework, William J. Balfour
Master's Theses
Modeling and simulation tools are exceptionally useful for designing aerospace systems because they allow engineers to test and iterate designs before committing the massive resources required for system realization. The Horizon Simulation Framework (HSF) is a time-driven modeling and simulation tool which attempts to optimize how a modeled system could perform a mission profile. After 15 years of development, the HSF team aims to achieve a wider user and developer base by releasing the software open source. To ensure a successful release, the software required extensive testing, and the main scheduling algorithm required protections against new code breaking old functionality. …
Autonomous Payload Design With Systems Engineering, Michael Downs, Christopher James Liebhart 2nd
Autonomous Payload Design With Systems Engineering, Michael Downs, Christopher James Liebhart 2nd
Williams Honors College, Honors Research Projects
The design will be an autonomous payload consisting of auto deployment of a drone running an autonomous mission of mapping the terrain around a grounded rocket. The project is part of the Akronauts payload project for the 2022 Spaceport competition. It will include the development of a ground station for monitoring and controlling the drone and the transfer of live data to the station and a computer on board the rocket. The project will aim to use system engineering techniques to accomplish this in the hope of providing documentation and thus insight into the best way to develop a multi-disciplinary …
Cultivating Creativity In Aerospace Systems Engineering To Manage Complexity, Kenneth Lucas Dodd
Cultivating Creativity In Aerospace Systems Engineering To Manage Complexity, Kenneth Lucas Dodd
Master's Theses
In recent decades, complexity in aerospace programs has been increasing, leading to large budget and schedule overruns. Many of the risks of complex system development can be attributed to the inadequacy of linear methods when applied to nonlinear domains, i.e., oversimplification in a program amplifies the amount of risk produced when a system behaves unexpectedly. Effectively managing complexity involves responding to the various sources of complexity, whether it appears in the objective behavior of the system itself or in the subjective behavior of the people developing it. Thus, the engineering of complex systems requires nonlinear modeling methods of the system …
Configuration Management Challenges Of Model Based Systems Engineering On Multiple Variant Aircraft Fleets, David R. Zubowski
Configuration Management Challenges Of Model Based Systems Engineering On Multiple Variant Aircraft Fleets, David R. Zubowski
Journal of Aviation/Aerospace Education & Research
Naval Air Systems Command (NAVAIR) is moving from traditional Systems Engineering (SE), focusing on managing documentation, to Model Based Systems Engineering (MBSE), focusing on a system model (All Partners Access Network, n.d.). As NAVAIR transitions to an MBSE standard, controlling the Configuration Management (CM) of a fleet of a single series of aircraft in varying states of engineering change incorporations will be critical. Traditional systems engineering and configuration management are both text document focused disciplines that have existed since the end of World War II. The method chosen to conduct the research was by performing a case study on MBSE …
Subsystem Failure Analysis Within The Horizon Simulation Framework, Ian M. Lunsford
Subsystem Failure Analysis Within The Horizon Simulation Framework, Ian M. Lunsford
Master's Theses
System design is an inherently expensive and time consuming process. Engineers are constantly tasked to investigate new solutions for various programs. Model-based systems engineering (MBSE) is an up and coming successful method used to reduce the time spent during the design process. By utilizing simulations, model-based systems engineering can verify high-level system requirements quickly and at low cost early in the design process. The Horizon Simulation Framework, or HSF, provides the capability of simulating a system and verifying the system performance. This paper outlines an improvement to the Horizon Simulation Framework by providing information to the user regarding schedule failures …
