Relational and technological process concept utilizing a human-in-the-loop-centered methodology for USSOCOM

Abstract

The Department of Defense (DoD) employs broad human factors requirements across various applications, resulting in a universal application of the same standards to a multitude of DoD acquisition systems. In unconventional warfare, specifically within missions conducted by US Special Operations Command (USSOCOM), operators face intensified workloads and domain-specific challenges that current human factors considerations do not adequately address. The objective of this dissertation aims to introduce and validate the Relational and Technological Capstone (RTC), which expands upon existing human factors requirements through both architectural and behavioral diagrams in a well-defined set of methodology-driven process steps. In referencing the system lifecycles as defined by the Defense Acquisition University (DAU) and the International Council on Systems Engineering (INCOSE), the objective is to diversify and enhance the consideration of Human Systems Integration (HSI) requirements in USSOCOM platforms by addressing the unique challenges posed by intensified workloads and domain-specific ontologies. The RTC employs a methodology-driven approach utilizing architectural, behavioral, and parametric diagrams. It integrates with Model Based Systems Engineering (MBSE) and the Systems Modeling Language (SysML) to improve the design of human-system interactions, incorporating a Special Operations Task List and Performance Shaping Factors (PSFs) into aggregated performance values. The results of this dissertation demonstrate the efficacy of RTC within MBSE, showcasing its value through improved design processes and as a foundation for new programs. The RTC can integrate existing models to further benefit customer needs through initiatives like Engineering Change Proposals (ECPs) as well as assist starter models for new programs and projects. The containment tree format aids in developing USSOCOM MBSE and opens possibilities for automation tools as well as an easily transferrable modeling package for future use on all complex systems. Continual use of RTC contributes to the maturity of MBSE models and diagrams, fostering the evolution of a federation-of-models and Program of Record standards. This not only benefits subsequent SOCOM programs and projects but also facilitates the emerging field and methodology of mission engineering to realize and forecast capability gaps before a system reaches the implementation and integration phase. The ultimate goal is to center the RTC around the operator, ensuring man-machine compatibility and optimization throughout special operation acquisitions.
