The thin film transistor-liquid crystal display (TFT-LCD) industry is naturally capital-intensive, with a typical fab requiring an investment of a few billion dollars. A cutting-edge TFT-LCD fab contains highly expensive process equipment performing complicated manufacturing operations and large material handling equipment connecting this process equipment. Because idle equipment and more than necessary WIP (work-in-process) lead to high operational costs, production must take place at full capacity with high utilization of resources and must employ just-in-time principles that require on-time delivery with minimum WIP, in order to ensure that the fab remains globally competitive. Thus, optimal management of production capacity is critical, and consequently, efficient production planning and scheduling pose big challenges to the TFT-LCD industry. In this paper, a framework of simulation-based production management is proposed for a TFT-LCD fab. The proposed framework integrates a material handling simulation with production simulation that progresses using agent-based collaborative decision-making. Thereby, it is enabled for individual process equipment and WIP to select WIP and process equipment, respectively, in their own preference. Particularly, the proposed simulation process is driven by material handling request from process equipment, rather than a process request-driven approach. The proposed framework and simulation model are validated by an experimental study on a hypothetical TFT-LCD fab
