基于TOC与OEE的生产电子看板系统

Electronic display board system based on the TOC theory and OEE

针对工厂生产管理中的产能约束与瓶颈问题,对生产瓶颈监测和生产流程改善等方面进行了研究,对TOC理论、OEE指标和电子看板三者结合开发生产电子看板系统的思路进行了归纳,提出了一种基于工业以太网现场采集及输出节点模块WAGO750-881的生产瓶颈挖掘和OEE损失分析的电子看板系统。利用新的瓶颈挖掘和生产流程改进方法在钻头生产企业中的生产线中的应用进行了效果测试。实验结果表明,钻头生产线的瓶颈工序为铣凹槽,在39.8%的OEE损失中由凹槽机待料所引起的占19.2%,所设计的电子看板系统可以提高企业的工作效率和流程改进效果。

Aiming at the capacity constraint and bottleneck of factory production management,many issues were studied include monitoring of production bottlenecks and the improvement of production process. The idea of electronic display board system,baesd on TOC theory,OEE index and electronic display board,was summarized. The electronic display board system of mining production bottlenecks and the analysis of OEE loss was proposed based on two cores：field data collection with industrial Ethernet and output node module WAGO750-881.Feasibility of the theory was verified in actual factory experiment,it was found that the bottleneck procedure of drill production line was milling groove. The results indicate that among the 40%loss of OEE,the loss caused by groove machine＇s waiting for material occupied 19.2%,the design of electronic display board system can increase the efficiency of enterprises and the effect of process improvement.
