A New Paradigm Integrating Business Process Modeling And Use Case Modeling, Barclay Brown
A New Paradigm Integrating Business Process Modeling And Use Case Modeling, Barclay Brown
Electronic Theses and Dissertations
The goal of this research is to develop a new paradigm integrating the practices of business process modeling and use case modeling. These two modeling approaches describe the behavior of organizations and systems, and their interactions, but rest on different paradigms and serve different needs. The base of knowledge and information required for each approach is largely common, however, so an integrated approach has advantages in efficiency, consistency and completeness of the overall behavioral model. Both modeling methods are familiar and widely used. Business process modeling is often employed as a precursor to the development of a system to be …
Model-Based Systems Engineering Approach To Distributed And Hybrid Simulation Systems, John Pastrana
Model-Based Systems Engineering Approach To Distributed And Hybrid Simulation Systems, John Pastrana
Electronic Theses and Dissertations
INCOSE defines Model-Based Systems Engineering (MBSE) as "the formalized application of modeling to support system requirements, design, analysis, verification, and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases." One very important development is the utilization of MBSE to develop distributed and hybrid (discrete-continuous) simulation modeling systems. MBSE can help to describe the systems to be modeled and help make the right decisions and partitions to tame complexity. The ability to embrace conceptual modeling and interoperability techniques during systems specification and design presents a great advantage in distributed and hybrid simulation systems …
Systems Geometry: A Methodology For Analyzing Emergent System Of Systems Behaviors, Christina Bouwens
Systems Geometry: A Methodology For Analyzing Emergent System Of Systems Behaviors, Christina Bouwens
Electronic Theses and Dissertations
Recent advancements in technology have led to the increased use of integrated ‘systems of systems’ (SoS) which link together independently developed and usable capabilities into an integrated system that exhibits new, emergent capabilities. However, the resulting SoS is often not well understood, where secondary and tertiary effects of tying systems together are often unpredictable and present severe consequences. The complexities of the composed system stem not only from system integration, but from a broad range of areas such as the competing objectives of different constituent system stakeholders, mismatched requirements from multiple process models, and architectures and interface approaches that are …
Critical Success Factors For Evolutionary Acquisition Implementation, Brig J. Bjorn
Critical Success Factors For Evolutionary Acquisition Implementation, Brig J. Bjorn
Electronic Theses and Dissertations
Due to extensive challenges to the efficient development and fielding of operationally effective and affordable weapon systems, the U.S. employs a complex management framework to govern defense acquisition programs. The Department of Defense and Congress recently modified this process to improve the levels of knowledge available at key decision points in order to reduce lifecycle cost, schedule, and technical risk to programs. This exploratory research study employed multiple methods to examine the impact of systems engineering reviews, competitive prototyping, and the application of a Modular Open Systems Approach on knowledge and risk prior to funding system implementation and production. In-depth …
Development Of A Cognitive Work Analysis Framework Tutorial Using Systems Modeling Language, Wilfred Henry Wells
Development Of A Cognitive Work Analysis Framework Tutorial Using Systems Modeling Language, Wilfred Henry Wells
Electronic Theses and Dissertations
At the present time, most systems engineers do not have access to cognitive work analysis information or training in terms they can understand. This may lead to a disregard of the cognitive aspect of system design. The impact of this issue is system requirements that do not account for the cognitive strengths and limitations of users. Systems engineers cannot design effective decision support systems without defining cognitive work requirements. In order to improve system requirements, integration of cognitive work requirements into the systems engineering process has to be improved. One option to address this gap is the development of a …
