摘　　要：柔性制造系统(FMS)的数控单元层调度,按先到先加工、最短时间规划(STP)和最小松弛度(LLD)生产调度原则对计划进行排序。通过工艺信息获得完成该条计划的资源和设备类型,计算该型设备的现有负荷,将计划指定到负荷最小设备上。每增加一条计划要重新计算设备负荷,直到安排完所有设备的月执行计划止。For scheduling of CNC (computer numerical control) cell layer for flexible manufacturing system (FMS), the sequence of production-plan is ordered according to some of scheduling rules such as first manufacturing, shortest time programming (STP), least laxation degree (LLD). The resource and machine types for the plan was gotten through the process information, and the existing load of the machine type was computed, the production-plan was assigned to the machine whose load is the lowest. It’s necessary for added a plan to compute the machine load over again, until the plans on all machine are ordered.
