摘要： 针对目前装配线仿真研究缺少模型检验步骤而导致仿真结果不可信的问题，在总结目前装配线仿真研究的基础上，引入两次仿真模型有效性的检验过程，提出完整的装配线仿真流程。为验证该流程的有效性，以实际装配线为例，在分析布局与工艺流程的基础上，考虑物流线布局、瓶颈机器数量、AGV数量和AGV速度对产能的影响，设计并基于Plant Simulation软件建立24种方案。所有方案仿真模型有效性的检验通过后，通过比较各方案的产能与机器利用率得到最佳方案。仿真结果表明，优化后的产能较初始方案提升约227%，瓶颈机器利用率提升约51%，平均机器利用率提升约121%。所提仿真优化流程可行且有效，可为装配线仿真研究与应用提供指导，对其他生产领域的仿真研究也具有借鉴意义。

Abstract: To solve the problem that the simulation research results are not credible by lacking the procedure of model verification for the assembly line, the model's verification process is twice introduced based on the summary of the current simulation research, and a complete simulation procedure for the assembly line proposed. To verify the effectiveness of the procedure, taking the actual assembly line as an example, the impact of logistics line layout, the number of bottleneck machines, AGV's quantity and AGV's speed on production capacity are considered based on the analysis of layout and process flow, and 24 schemes are designed and constructed based on Plant Simulation software. After all the simulation models are verified, the best scheme is obtained by comparing the productivity and the utilization rate of the machine. The simulation result shows that the optimized capacity is increased by 227% compared with the original plan, the bottleneck machine utilization rate increased by 51%, and the average machine utilization rate by 121%. It is concluded that the proposed simulation optimization procedure is feasible and effective, which can provide guidance for the simulation research and application of the assembly line, and has reference significance for the simulation research in other production fields.
