Abstract
Modern systems are evolving continuously with rapid technological advancements and refreshments throughout the life cycle. Competitive organizations developing such systems constantly seek to apply holistic techniques for identifying problems that need to be solved and evaluating all possible technological solutions to guide the system development effort. The Model-Based Systems Engineering (MBSE) philosophy and tools are gaining widespread adoption in complex system development and claim several benefits over the traditional document-centric SE approach. This thesis investigates some model-centric implementations in the system development process. An organization's technology/platform development process, referred to as the Product Life Cycle (PLC) process, is analyzed to understand the workflow and expected outcomes necessary to progress in a system development effort. The phase- and gate-based process activities and resulting deliverables in the ideation phase are modeled and analyzed. A data modeling approach is also investigated to integrate the PLC process model with a system model. To develop the system architecture model of a thrust reverser actuation system (TRAS) concept, an MBSE methodology and framework are implemented. The solution boundary for subsystem alternatives is explored, and requirements are analyzed to compare how well the system solution matches the problem. The traditional, text-based requirements are examined to identify deficiencies, and an attribute-based approach is investigated to improve requirements' quality as well as perform requirement development and management activities more interactively and consistently. Overall, the key takeaways of the investigated model- and data-centric approach is summarized, and some insight on the path forward for future implementation is discussed.
