A Unified Enterprise-Wide Cost Modeling Framework For Engineering Applications Based On Systems Engineering Principles, Yousuf S. Mohammed
A Unified Enterprise-Wide Cost Modeling Framework For Engineering Applications Based On Systems Engineering Principles, Yousuf S. Mohammed
Mechanical & Aerospace Engineering Theses & Dissertations
In the present research the problem of enterprise-wide cost modeling is approached from a systems engineering standpoint. What this does is to use each stage of product life cycle to obtain useful information that helps in estimating the cost of the system. Once a generic framework is developed for estimating the core cost, layers of other factors that affect the cost are applied to the core cost, such as risk and uncertainty, maintainability, supply-chain and socioeconomic conditions. The cost model is expanded to accommodate a product domain ranging from a simple object to a system in the following hierarchy: System, …
Evaluating Network Analysis And Agent Based Modeling For Investigating The Stability Of Commercial Air Carrier Schedules, Sheila Ruth Conway
Evaluating Network Analysis And Agent Based Modeling For Investigating The Stability Of Commercial Air Carrier Schedules, Sheila Ruth Conway
Engineering Management & Systems Engineering Theses & Dissertations
For a number of years, the United States Federal Government has been formulating the Next Generation Air Transportation System plans for National Airspace System improvement. These improvements attempt to address air transportation holistically, but often address individual improvements in one arena such as ground or in-flight equipment.
In fact, air transportation system designers have had only limited success using traditional Operations Research and parametric modeling approaches in their analyses of innovative operations. They need a systemic methodology for modeling of safety-critical infrastructure that is comprehensive, objective, and sufficiently concrete, yet simple enough to be deployed with reasonable investment. The methodology …
Streamlining The Change-Over Protocol For The Rpa Mission Intelligence Coordinator By Way Of Situation Awareness Oriented Design And Discrete Event Simulation, John P. Machuca
Theses and Dissertations
Incredible loiter times coupled with the ability to make extremely detailed collections at significant stand-off distances with a relatively expendable platform has made demand for, and diversity of, Remotely Piloted Aircraft (RPA) operations grow at voracious rates. Conversely, financial resources are becoming increasingly constrained. As such, innovators are looking to maximize the effectiveness of existing personnel and assets by considering concepts such as simultaneous Multiple Aircraft Control (MAC) by a single aircrew. Research has identified procedural inefficiencies in current operations as well as substantial impediments to MAC implementation, including dynamic task saturation and communication challenges. An identified inefficiency afflicting both …

This effort constitutes a systems engineering approach in which the materials science, ultrasound structural health monitoring, flight and maintenance operations, and relevant aeronautical policies and programs are involved to explore the evolution and characterization of structural cracks in aircraft fuselage structures in which the loads are varying. During flight, an aircraft fuselage skin and structure are subjected to varied cyclic loads, which can cause embedded cracks and other damage features to change their characteristics due to loading effects. The current research is based in the application of finite element modeling techniques using COMSOL and PZFLEX software to characterize the behavior …
Analysis Of The Impact Of Data Normalization On Cyber Event Correlation Query Performance, Smile T. Ludovice
Analysis Of The Impact Of Data Normalization On Cyber Event Correlation Query Performance, Smile T. Ludovice
Theses and Dissertations
A critical capability required in the operation of cyberspace is the ability to maintain situational awareness of the status of the infrastructure elements that constitute cyberspace. Event logs from cyber devices can yield significant information, and when properly utilized they can provide timely situational awareness about the state of the cyber infrastructure. In addition, proper Information Assurance requires the validation and verification of the integrity of results generated by a commercial log analysis tool. Event log analysis can be performed using relational databases. To enhance database query performance, previous literatures affirm denormalization of databases. Yet database normalization can also increase …

Leading Indicator Analysis For High Speed Sled Test Programs, Laurie C. Knorr
Theses and Dissertations
Leading Indicators (LI) were introduced to the Systems Engineering (SE) community in 2005. These measures are used to evaluate the effectiveness of how a specific work activity is applied on a project in a manner that provides information about impacts that are likely to affect the system performance. The LIs are designed to give a project manager/systems engineer insight into where their development project is heading and a chance to implement corrective actions early. This research strives to apply LIs to the testing community, specifically high speed sled testing, to improve the testing process and, in turn, improve the quality …

Modeling Forward Base Camps As Complex Adaptive Sociotechnical Systems, Lori Ann Miller
Masters Theses
Work for this thesis focuses on managing complexity within complex adaptive sociotechnical systems by using model based systems engineering and virtual engineering tools. The hypothesis of the work is that integrated virtual models can be used to increase the understanding of these complex adaptive sociotechnical systems, resulting in a reduction in the perceived complexity. This was tested by the use of a two factor survey given to experts of a system (the customer and members of the model design team) and to a target user-group. This group received a demonstration and had hands on experience with a preliminary model of …
Search-Based System Architecture Development Using A Holistic Modeling Approach, Renzhong Wang
Search-Based System Architecture Development Using A Holistic Modeling Approach, Renzhong Wang
Doctoral Dissertations
"This dissertation presents an innovative approach to system architecting where search algorithms are used to explore design trade space for good architecture alternatives. Such an approach is achieved by integrating certain model construction, alternative generation, simulation, and assessment processes into a coherent and automated framework. This framework is facilitated by a holistic modeling approach that combines the capabilities of Object Process Methodology (OPM), Colored Petri Net (CPN), and feature model. The resultant holistic model can not only capture the structural, behavioral, and dynamic aspects of a system, allowing simulation and strong analysis methods to be applied, it can also specify …

Dynamic Model-Based Systems Engineering Using Xml Metadata Interchange, Dustin Scott Nottage
Dynamic Model-Based Systems Engineering Using Xml Metadata Interchange, Dustin Scott Nottage
Masters Theses
"Designing systems presents an engineer with numerous design choices based on multiple conditions and constraints. Base camp planning must take into account the number of soldiers, the permanency of the base, the location of the base, etc. To help alleviate the complexity of constructing a base camp, a model-based systems engineering approach is used. This method creates and integrates models for all of the facilities that can make a base camp, as well as interactions between facilities and required utilities for each. The goal is to have a camp design, and then solve a system of equations to solve for …
