AICOS — The Planetary Operating System for Decisions: Decision Infrastructure as a Governance-First Computational Paradigm

This work introduces the concept of Decision Infrastructure, a computational framework designed to transform complex strategic decision-making into structured, auditable, and economically optimized processes. The paper presents AICOS — The Planetary Operating System for Decisions, a governance-first intelligence infrastructure developed under the AX Decision Forge technology category. The architecture integrates formal decision modeling, risk and irreversibility analysis, scenario simulation, governance validation, and deterministic decision replay mechanisms. Unlike traditional analytics or AI systems that primarily focus on prediction and data processing, Decision Infrastructure focuses on the structured governance of high-impact decisions. The AICOS architecture enables institutions to evaluate strategic actions under uncertainty while maintaining transparency, accountability, and economic optimization. The proposed framework is particularly relevant for sectors characterized by high capital intensity, long decision horizons, and systemic risk exposure, including energy infrastructure, financial systems, logistics networks, and large-scale strategic investments. By formalizing decision processes into reproducible computational artifacts, AICOS provides a foundation for a new generation of digital infrastructure where decisions themselves become structured, verifiable, and replayable objects within institutional systems. The work positions AICOS as a foundational architecture for governance-first AI systems and for the emerging category of Decision Infrastructure.
