生产线仿真是对制造车间进行生产规划、调度的有效手段。本文针对某轨道交通装备制造企业SMT车间AGV调度系统设计过程中AGV数量规划、路径规划等问题，建立了基于Plant Simulation的生产系统仿真模型，以物料配送时间最小化为目标，总结最优车辆配置与布局方案，为车间生产物流方案提供决策支持。 Production line simulation is an effective means of planning and scheduling in the manufacturing workshop. In this paper, based on the AGV quantity planning and path planning in the AGVS design process of an electronics manufacturing enterprise in rail transportation industry, a production system simulation model based on Plant Simulation is established to minimize the material deliv-ery time, summarize the optimal vehicle configuration and layout scheme, and provide decision support for production logistics solutions in electronics manufacturing plants.
