剛好及时 Just-In-Time It causes the other 6 wastes It hides problems (kaizen opportunities) 因此造成了其他六种的浪费 它掩藏问题(改善的机会) Poor production planning Have excess capacity “Keep the machines running!” “We need to keep everybody busy! Poor Layout Design No / Bad Flow Job Shop / Functional Layout Unbalanced work content 没有良好的生产规划, 能力过剩 但我们必须保持机器运行 ! 需要让大家忙”! 没有良好的布局设计, 没有/坏的流程流 功能布局 工作内容 不平衡  Operator Balance Chart (OBC) --  another 5 station line 操作员平衡表 – 另外的5个岗位的生产线 65” 35” 30” 40” 30” Work Element Times for each station 每个岗位的工作成分时间 Total StationCycle Time 所有岗位的周期时间 TT = 60” Who is overloaded? 谁负荷过重 How balanced is this? 如何平衡 Work Stations 工作岗位 Balance to Planned Cycle Time 根据计划的周期时间来平衡 Takt Time (TT): 节拍 The customer demand rate. 顾客要求的速度 A B C D Planned Cycle Time (PCT): 计划的周期时间 A production rate that is slightly faster than takt time that provides a very small capacity cushion. 一种比节拍稍快,可以提供小小的产能弹性的生产速度 Operator Cycle time (CT): 操作周期时间 Time an operator requires to go through all of his or her work elements one time. 操作员需要做完所有的工作要素一次所用的时间 Planned Cycle Time should be 95% of TAKT. 计划周期时间应为节拍时间的95%。 - Lower for new cells or unreliable operations. 对于新的单元或是不稳定的工厂，比率要低些。 Number of Operators Calculation  操作员人数的计算 Example: 例子 Takes 90 seconds of labor to assemble part A 需要花90秒工时组装 A部件 Demand calls for a part A every 30 seconds 需求要每30秒出1件A部件。 How many people will we need to keep up? 我们我们需要多少人保证满足需求？ Calculation计算 Total CT PCT = sec sec = Number of Operators 操作员人数 = ____ Operators Balanced line still has waste  平衡过的生产线仍然有浪费 Waste 浪费 PCT = 60” A B C D 55” 52” 55” 38” Balanced to Takt Take out waste rebalance again to Eliminate 2nd position 取出浪费并再平衡一次， 消除第2个岗位 PCT = 60” A B C 60” 60” 60” Improved 改善 八 Standardized Work 标准工作 Standardized Work...
