一种基于Em-Plant的生产线多层次仿真建模方法

A Multilevel Simulation Modeling Method for Production Line Based on Em-Plant

为解决军工生产线建设缺乏合理物流线布局和生产策略,使得无法量化地评估生产系统优劣的问题,介绍一种基于Em-Plant的生产线多层次仿真建模方法。建立包含零件源、加工中心、立体库和充电区等模块化、多层次的嵌套建模单元,在此基础上设计物流控制调度策略,并通过仿真模型验证。结果表明:该方法能实现建模的易用性和灵活性的统一,在实际投产之前就生产制造系统作出快速布局和合理规划,已成功运用于某型弹部件生产线。

Because lack of reasonable logistics line layout and production strategy for the construction of military production lines,it is impossible to evaluate the advantages and disadvantages of production system quantitatively.For solving this problem,introduce a multilevel simulation modeling method for production line based on Em-Plant.Set up modular and multilevel nested modeling units including parts source,machining center,stereo library and charging area,on this basis,logistics control and scheduling strategy is designed and verified by simulation model.The results show that the method can achieve the uniformity of easy use and flexibility of modeling.Before the actual production,the production system is quickly laid out and rationally planned.It has been successfully applied to the production line of certain type ammunition parts production line.
