精益生产之线平衡模式LineBalanceModels中英文版.ppt

Line Balance Model Model will build the following graph which shows how we should plan to: Staff in equal increments (to limit having to re-balance line) Vary hours worked to get complete coverage of demand requirements Process Balance Model:Step 4 (Cont.) Line Balance Model 模型可建立如下图说明: 每一阶段需要的人力 完成任务需要的工作时间 过程平衡模型:步骤 4 (续.) Line Balance Model Step 5 Plot current operating range to determine labor reduction required to meet operating goals Process Balance Model:Step 5 The model has calculated that at a rate of 150 units/day, the area should be working a 6 hour shift with 7 processors. This is 2 fewer processors than their current environment. Line Balance Model 步骤 5 绘制目前的作业范围来决定完成目标可节约的人力 过程平衡模型:步骤 5 在 150 单位/天的需求下, 需要每班 6 小时， 7 位作业员. 比目前人力少两人 Line Balance Model Step 6 Group process tasks in logical and efficient manner that does not violate design principles (eg - (task time takt rate time) Process Balance Model:Step 6 Line Balance Model 步骤 6 合乎逻辑与共效率的团队工作不违反设计原则 (例 - (task time takt rate time) 过程平衡模型:步骤 6 Line Balance Model This worksheet provides a summary of inputs used and outputs generated for each window category that is run through the model. This worksheet is automatically created and updated by the model. Model Summary Line Balance Model 这个工作表提供了在本模式运行下的按窗口分类的投入和产出的总结。这份表格是自动生成的并能通过该模式更新。 模型总结 Line Balance Model Approach #1: Calculation Notes (Step 3) Max Labor Efficiency Best in class is 65% Assumption is that labor efficiency declines the more tasks each processor is asked to perform Max hrs per shift Should be set to 11 hours to obtain optimal coverage of requirements Max Demand (units/ hour) = Max Demand Requirement/Max hrs per shift Max Demand (units/minute) = Max Demand (units/hour) / 60 Takt Time (seconds/unit) = 60 / Max Demand (units/minute) This is the amount of time between products exiting - This is also the maximum amount of process time that any one workstation should perform without compromising the line flow Total Assembl
