Implementation of various cell types according to products attributes, level of operators , production quantity, layout modifications are possible flexibly 可以根据产品的特性, 工人的熟练程度,及产量采用各种各样的 Cell拉型, 车间的布局显得良好多变.
Cell Production Method 小单元生产方式
The Cell Production Method is one of the best solutions of manufacturing styles for small lot production, in which assembly and work are done In one single process, by using small manufacturing instruments(tools), by operation of one or a few workers. Cell 式生产是一种小批量生产制造的最佳方案, 它通过 使用较小型的制造设备,工具,由一个或几个工人, 在 一个非常简单的工序内完成装配等等的工作.
Space reduction by removal of conveyor 因移走了传送带而节约了空间 Elimination of loss by reducing in-between spaces 因缩减了工位间的间隙而节约了空间 (消除了空间的损失)
