Comprehensive System Modeling of a Micro-Reformer for SynGas Production using MBSE Principles within the Capella/ARCADIA Framework

Abstract

This study presents the design and modeling of a micro-reformer for SynGas production using Model-Based Systems Engineering (MBSE) principles within the Capella- ARCADIA framework. The main objective was to create a comprehensive system model capturing the operational, functional, and physical architectures of the reformer, ensuring that each stage of design aligned with stakeholder requirements and performance goals. The research began with Operational Analysis to identify stakeholder needs and define system boundaries, forming a high-level understanding of essential interactions. This foundation guided the System Analysis phase, where system functionalities and expected behaviors were articulated, detailing how the reformer should interact with external elements. Logical Architecture further refined the design by decomposing the system into abstract components with defined interaction principles, maintaining flexibility in implementation. In the final Physical Architecture phase, these abstract elements were translated into concrete, implementable components, laying out the structural design ready for potential construction. Results demonstrate that MBSE, applied through Capella, provides a structured approach to complex system design, promoting consistent requirements management and enabling iterative valida tion at each design phase. Challenges such as coordinating interdisciplinary inputs and maintaining model coherence across phases were effectively managed through Capella’s structured methodology, underscoring the reliability and adaptability of MBSE in complex energy system projects.
