10、重大变化的分装线从总装线中分离出来Shifts the subassembly experiencing the wide variation off the main assembly line 总装线上设有“节拍器”“Pacemaker”established on final assembly lineo例如，生产线按节拍时间连续移动i.e.,continuous movement of the line at the takt time rate总装线“拉动”分装线 Final assembly“pulls”from subassemblyo分装线的工作与总装线分开 Subassemb

11、ly work separated from final assembly work o适应产品的变化 Facilitates product variationo在生产支线/生产单元完成分装工作 Subassemblies completed on“spur”line/cello例如，附属于总装线的生产支线/生产单元 i.e.,attached to main lineo分装线在需要使用零件的地方才介入总装线 Subassemblies enter at point of use从后面供应物料 Material supplied from backo多人的分装线单元要放在“背后”，因为分装线

12、的输出是以其它零件和物料一样的方式，供应给总装线的。Multi-operator sub-assembly cell is on the“back”,since its output is presented to the main line operators just like other parts and materials.按使用次序安排物料 Materials sequenced in order of use开放式平行线布局 Parallel(Open Room)Layout 需求大High demand 节拍时间短Shorter takt time 两个工人2 operator
