【摘要】：设置瓶颈缓冲对于提高制造系统稳定性和产出效率具有重要意义。针对空气悬架制造过程中的多工件、多工序和多设备并行生产的复杂工况,根据设备故障度和维修度、在制品库存成本、瓶颈停工损失以及异常生产波动因素等,建立了使瓶颈工序停机等件时间最短且成本损失最小的基本瓶颈缓冲量模型,并针对批量加工和压件转运策略造成的工序间歇进行修正。以空气弹簧减震器机械结构关键零件的生产排程为例,验证了该模型能准确预测瓶颈缓冲量。
[Abstract]:It is very important to set bottleneck buffer to improve the stability and output efficiency of manufacturing system. In view of the complex working conditions of multi-workpiece, multi-process and multi-equipment concurrent production in the air suspension manufacturing process, according to the equipment failure degree and maintenance degree, in-process inventory cost, bottleneck stoppage loss and abnormal production fluctuation factors, etc. A basic bottleneck buffer model is established, which can make the bottleneck process stop and lose the minimum cost, and the batch processing and press transfer strategy are modified. Taking the production schedule of the key parts of the mechanical structure of the air spring shock absorber as an example, it is verified that the model can accurately predict the bottleneck buffer.
