- W4387475768 abstract "Many semiconductor fabrication plants (fabs) prefer simulation-based decision making for vehicle dwelling policies because it can capture a fab’s scalability and complexity. Vehicle dwelling policies assign idle vehicles to intra-bay and outer loops in automated material handling systems (AMHSs) to respond quickly to transportation demands. Fabs are motivated to control vehicle dwelling policies when fabs experience significant fluctuations, i.e., changes in product mix. Fab operators evaluate manually designed candidate solutions because it is time-intensive to run a large-scale simulation with numerous potential solutions. To determine a vehicle dwelling policy, we propose a simulation optimization approach based on Bayesian optimization (BO) with class-based clustering. BO adaptively traces efficient vehicle dwelling policies based on a surrogate model and an acquisition function. Class-based clustering alleviates the high dimensionality of the design space by grouping bays into a small number of classes. By striking a balance between the complexity of the design space and the quality of the solutions, our proposed policy significantly reduces the number of simulation runs required to determine efficient vehicle dwelling policies. We conclude that BO with class-based clustering is more advantageous than using a genetic algorithm (GA) and using heuristics. <italic xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>Note to Practitioners</i> — This study is motivated by the difficulties in simulation-based decision making for optimal vehicle dwelling policies in a semiconductor wafer fab’s AMHS. While existing research has demonstrated the effectiveness of simulation analysis on operational planning in a fab, simulation optimization for a vehicle dwelling policy is still problematical due to the heavy computation burden for simulation runs and its large design space with the increased number of control variables in a fab. Therefore, we develop a simulation optimization approach using BO with class-based clustering. The proposed approach significantly reduces the number of simulation runs to obtain efficient vehicle dwelling policies, resulting in decreased delivery times and vehicle utilization rates." @default.
