Simulation of Semiconductor Manufacturing Supply-Chain Systems With DEVS, MPC, and KIB

摘要: The dynamics of high-volume discrete-part semiconductor manufacturing supply-chain systems can be described using a combination Discrete EVent System Specification (DEVS) and model predictive control (MPC) modeling approaches. To formulate the interactions between discrete process its controller, another called Knowledge Interchange Broker (KIB) is used. A robust scalable testbed supporting DEVS-based modeling, MPC-based controller design, KIBDEVS/MPC interaction developed. suite experiments have been devised simulated this testbed. flexibility approach for simulating, evaluating stochastic models under alternative schemes detailed. illustrates benefits challenges associated with developing realistic policies. simulation environment demonstrates importance explicitly defining exposing subsystems complex systems.
