AI Act-Oriented Risk Assessment Framework for High-Risk Intelligent Systems

The European Union's Artificial Intelligence Act (AI Act) establishes a tiered regulatory framework that imposes stringent requirements on high-risk AI systems, necessitating robust and transparent risk assessment methodologies. This paper presents a comprehensive system-level risk assessment framework specifically designed for high-risk intelligent systems as defined by the AI Act. The framework integrates technical, governance, and socio-technical dimensions to evaluate risks across the entire lifecycle of an AI system, from conception and training to deployment and continuous monitoring. We examine structural trade-offs between system performance and safety, architectural patterns that support compliance, and the infrastructure needed for ongoing validation. The treatment addresses issues of robustness, fairness, sustainability, and accountability, drawing on insights from large-scale systems engineering, regulatory science, and AI ethics. Through cross-domain comparisons and case illustrations, the framework is shown to be adaptable to sectors such as healthcare, critical infrastructure, criminal justice, and employment. The paper further explores policy implications and forward-looking perspectives on how such frameworks can evolve as AI capabilities and regulatory landscapes mature. This work aims to provide researchers, practitioners, and policymakers with a rigorous yet practical foundation for operationalizing AI Act requirements in the design and governance of high-risk intelligent systems.
