Abstract:
Model-Based Systems Engineering (MBSE) has emerged as a paradigm shift in the development
of complex systems, providing a holistic and integrated approach that transcends the limitations
of conventional document-centric Systems Engineering (SE) methodologies. The literature
identifies the traditional system development models like V-model, waterfall, and spiral models,
document-centric models, leading to disintegrated development, increased costs, and project
delays. This study focusses on employing ARCADIA, an integrated MBSE approach, to engineer
an IoT-based mesh radio network system utilizing Software-Defined Radio (SDR) technology.
ARCADIA a MBSE framework addresses the challenges of traditional document centric
methods in system engineering. First phase, operational analysis, was conducted to capture and
define stakeholder needs, operational environment, and conditions in which the system will
operate. System analysis built upon operational analysis to formalize system requirements and
articulate the dynamic behavior of the system. The third step involved defining the logical
architecture, treating the system as a white box. The final step involved the development of the
physical architecture, specifying how the system will be built, by defining system components,
detailing interfaces, and conducting a final tradeoff analysis, ultimately leading to the final
architecture of the system. ARCADIA implementation resulted in addressing the complexities of
SDR system through enhanced communication, collaboration, and integrity of people, processes,
and product. Its efficiency in requirement management, change management and seamless
verification and validation resulted in efficient system development as per the user requirements.
The cost benefit analysis identified the significant return on investment (ROI) of 10% on overall
project costs. The impact of this research extends beyond the present, setting a path for future
applications in various sectors like unmanned arial vehicle, aerospace, telecommunication,
energy systems, smart cities, healthcare, and transportation. This study, implementation of
MBSE for IoT based mesh radio network, opens doors for a transformative shift in approach to
develop complex system across commercial and defense landscapes.
