摘　　要：为解决柔性制造系统中资源重组引起的布局问题,采用面向对象的建模方法建立了柔性制造系统的虚拟仿真系统.该虚拟仿真系统通过对制造系统中各设备进行几何和行为建模,建立虚拟设备模型;采用生产计划流建立车间布局方案和调度模型.通过仿真,不仅能验证加工代码的正确性,还能根据加工工艺仿真结果分析布局的合理性和可行性,并对布局进行优化.最后,对2种布局进行了仿真,结果表明所建立的仿真系统是可行和有效的.In order to solve the problem of facility layout induced by resource recombination in flexible manufacturing systems, an object-oriented modeling method was proposed to construct the virtual prototype system of a flexible manufacturing system. By modeling of the geometry and behavior of each facility in a manufacturing system, virtual facility models are formed, and by adopting the production schedule flow, a facility layout scheme and dispatch model are constructed. The accuracy of NC （numerical code） can be validated, the rationality and feasibility of a layout scheme can be analyzed, and the layout scheme may be optimized by the simulation of a virtual prototype system. Finally, two different layouts were simulated. The simulation results show the effectiveness of the proposed method.
