基于层级仿真的U型钢结构件生产线产能综合优化OA

To address the capacity shortage caused by imbalanced processing times between workstations in a U-shaped steel structure production line,this paper proposes a Plant Simulation-based optimization method.A digital model of the production line is built,and the optimal buffer capacities,along with the optimal number of workstations for bottleneck processes(electroslag welding and shot blasting),are determined based on this model.A"hierarchical simulation"scheme is developed to reduce the number of simulation runs under multi-parameter combinations by progressively narrowing the search range and increasing precision.The resulting optimal configuration increases simulated capacity by 38.32%,raising weekly output from 3 212 to 4 443 units.This work provides a reference for capacity optimization of similar production lines.
