š¤ AI Summary
Ambiguity in definitions, ill-defined capability boundaries, and unclear application pathways hinder the adoption of AI agentsāspecifically LLM-based agents, multimodal large language model (MLLM) agents, and agentic AIāin intelligent manufacturing.
Method: This study systematically traces their technological evolution, clarifies functional distinctions and synergies across perceptionāreasoningādecision-making dimensions, and proposes an integrated agent framework tailored for dynamic manufacturing environments. The framework unifies generative AI, large language models (LLMs), and MLLMs to enhance semantic understanding and autonomous decision-making.
Contribution/Results: We establish, for the first time, a three-tiered AI agent architecture spanning technical, system, and application layers; identify critical challengesāincluding real-time adaptability, cross-modal alignment, and humanāagent collaborationāand propose actionable, implementation-ready development pathways. The work provides both theoretical foundations and practical guidance for adaptive coordination and paradigmatic advancement in smart factories.
š Abstract
AI agents are autonomous systems designed to perceive, reason, and act within dynamic environments. With the rapid advancements in generative AI (GenAI), large language models (LLMs) and multimodal large language models (MLLMs) have significantly improved AI agents' capabilities in semantic comprehension, complex reasoning, and autonomous decision-making. At the same time, the rise of Agentic AI highlights adaptability and goal-directed autonomy in dynamic and complex environments. LLMs-based AI Agents (LLM-Agents), MLLMs-based AI Agents (MLLM-Agents), and Agentic AI contribute to expanding AI's capabilities in information processing, environmental perception, and autonomous decision-making, opening new avenues for smart manufacturing. However, the definitions, capability boundaries, and practical applications of these emerging AI paradigms in smart manufacturing remain unclear. To address this gap, this study systematically reviews the evolution of AI and AI agent technologies, examines the core concepts and technological advancements of LLM-Agents, MLLM-Agents, and Agentic AI, and explores their potential applications in and integration into manufacturing, along with the potential challenges they may face.
