In general, the intrabay automation systems include the automated controls of the process tools, overhead hoist transports (OHTs), stockers, and rail shortcuts. These control systems are operated concurrently. They must be cooperated seamlessly to increase the system performance and to avoid deadlocks. In this paper, the behaviors of the intrabay automation systems are modeled using the distributed agent oriented Petri net (DAOPN). The fab intrabay DAOPN models are categorized into the new-order generation, OHT vehicle dispatching, zone control, path decision, and tool processing agent models. Finally, the DAOPN is defined, and the modeling procedures of the intrabay behaviors are all illustrated. Consequently, an experimental intrabay OHT loop is discussed and evaluated using the proposed DAOPN models and the DAOPN simulator.AutomationComputer simulationDatabase systemsDistributed computer systemsEnd effectorsMulti agent systemsPetri netsProcess controlUser interfacesDispatchingDistributed agent oriented Petri netDistributed multiagent systemFab intrabaysIntegrated circuit foundry fabOverhead hoist transportsIntegrated circuit layoutletter10.1109/TSMCA.2003.8173952-s2.0-0344961675
