Closed-Loop Multi-Agent Framework for Airborne Systems MBSE Requirements Standardization

Requirements engineering for aerospace systems needs rigorous standards compliance, clarity, and traceability due to stringent safety and reliability criteria. However, existing methods leveraging Large Language Models (LLMs) typically address isolated stages of the requirement engineering process without adequate consideration for compliance standards, closed-loop integration, and iterative optimization. This paper presents an innovative closed-loop multi-agent framework integrating LLMs within the multi-agent platform, specifically designed for aerospace Model-Based Systems Engineering (MBSE). The proposed architecture supports a closed-loop requirement engineering process encompassing requirement extraction, normalization, verification, and optimization. The resulting structured requirements are seamlessly exported to Capella, a leading MBSE modeling tool, ensuring compliance with DO-178C standards.
