摘　　要：针对烧结钕铁硼磁性材料甩带工序的生产特点:生产工单的需甩带量并非都小于甩带炉炉重的最大值;在甩带炉中加工的炉次的重量是个范围,非固定值;生产工单对应牌号在甩带库中的备料要在企业要求的范围内。从现场计划员的经验、历史生产实绩及现场的工艺约束中提取5类共11条规则。首先,通过是否常用牌号工单,是否长订单工单,设定甩带炉次重量;其次,按照工单优先级和现场工艺约束进行生产工单组炉;最后,根据历史生产实绩和设定的库存备料量进行甩带炉重和炉次的调整。将该方法应用于为该企业研发的生产计划子系统中,实际应用结果表明,该方法将工单拖期率由40%下降到20%,提高工单准时交货能力;优化甩带库库存备料,以实现企业的节能降耗。Aiming at the production characteristics of sintering Nd2Fe14 b magnetic materials： the production order＇ s required strip weight is not always less than the maximum weight of each furnace; each furnace＇ s weight is a range not a fixed value; the various grade stocks is within the required scope of the enterprise. Five Categories eleven rules were extracted from the experience of site plan- ners, historical production performance and production process constraints in this paper. First, set strip casting furnace＇ s weight ac- cording to whether common grade work sheet or long order work sheet; second, conduct work sheet＇ s group furnace according to work sheet priority and production process constraints; Finally, adjust furnace weight or furnace number based on historical production per- formance and production process constraints set inventory preparation weight. This method is applied to the production planning subsystem that developed for the enterprise. The actual application results show that this method improves the ability of work sheets on time delivery, reduces tardiness from 40 % to 20 % , optimizes inventory preparation, and realizes energy saving consumption reducing.
