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 promising the line flow ?Total Assemblers/Processors = ((Total Process Time (hrs) * Max Dmd Req (units/shift)) / Max hrs per shift) /Max Labor Efficiency ? The result is rounded up to the next whole assembler ? This is the number of assemblers/processors I should have to process the maximum demand requirement at the maximum labor efficiency ?Workstation Time (secs/workstation) = Total Process Time (hrs) * 60 * 60 / Total Processors ? 1 processor = 1 workstation ? This is the optimal amount of time that tasks should be grouped by to balance the line ?Labor Productivity (Units/Labor Hour) = Max Demand (units/hour) / Total Processors Control Line Balance Model 40 途徑 1: 計(jì)算說明 (步驟 3) ?最高勞動(dòng)效率 ?最好是 65% ?假設(shè)勞動(dòng)效率下降，需要每個(gè)操作工做更多的工作 ?每班最多工時(shí) ?應(yīng)該設(shè)為 11個(gè)小時(shí)以最好地滿足需要 ?最大需求 (units/ hour) = 最大需求需要 /每班最多工時(shí) ?最大需求 (units/minute) = 最大需求 (units/hour) / 60 ?Takt 時(shí)間 (seconds/unit) = 60 / 最大需求 (units/minute) ?這是現(xiàn)有產(chǎn)品之間的時(shí)間量 這也是每個(gè)工作站的最多的流程時(shí)間 ?全部裝配工 /操作工 = ((Total Process Time (hrs) * 最大需求需要 (units/shift)) / Max hrs per shift) /最高勞動(dòng)效率 ?這個(gè)結(jié)果接近下次的全部操作工 ?這是在最高勞動(dòng)效率下的滿足了最高需求下的操作工人數(shù) ?工作站時(shí)間 (secs/workstation) = Total Process Time hrs) * 60 * 60 / Total Processors ? 1 操作工 = 1 工作站 ?這是將任務(wù)分組的最佳時(shí)間 ?勞動(dòng)生產(chǎn)率 (Units/Labor Hour) = 最大需求 (units/hour) / 全部操作工 Control Line Balance Model 41 Approach 1: Team Exercise 1. Go to the Virtual Coach Exercise Tab and open the file titled: Windows R Us Line Balancing 2. Read the scenario and plete steps 1 through 4 using the spreadsheet titled: Windows R Us Line Balancing 3. Prepare a 5 minute presentation with your team answers. ? You have 45 minutes to build this part of a line balance model. ? Detailed instructions are on the next slide. Control Line Balance Model 42 Approach 1: 小組練習(xí) 1. 看虛擬輔導(dǎo)練習(xí)并打開以下抬頭的文件 : Windows R Us Line Balancing 2. 讀情節(jié)并完成第 1到第 4步，使用有以下抬頭的工作表格 : Windows R Us Line Balancing 3. 準(zhǔn)備 5分鐘的展示 4. 你有 45 分鐘的時(shí)間來建這個(gè)線平衡模型部分 ? 具體的指導(dǎo)顯示在下一個(gè)幻燈片上 . Control Line Balance Model 43 Exercise Objectives ? Teach the student how to balance a line mathematically ? Teach the student the method to relay out the line to realize the mathematical balance ? The exercise will develop: ? Takt Time chart ? Skill Matrix ? Proposed time calculation Control Line Balance Model 44 練習(xí)的目標(biāo) ? 教學(xué)生怎樣用數(shù)學(xué)方法來平衡一條線 ? 教學(xué)生對(duì)線進(jìn)行再布局的方法以實(shí)現(xiàn)數(shù)學(xué)上的平衡 ? 這個(gè)練習(xí)將制作出 : ? Takt 時(shí)間圖表 ? 技能距陣 ? 擬定時(shí)間的計(jì)算 Control Line Balance Model 45 Exercise Instructions 1. Using the Excel spreadsheet, look at the “Current times” tab to plete the “Current Takt Time Chart.” 2. Look at the “Current Staffing” tab to plete the “Skill Matrix” tab. 3. Use the three tabs and redivide the tasks to have a balanced number of tasks with the same number of people and same sequence as the original line. Note: ?A proposed layout is not to be made. ?Current extrusion data is not to be developed. ?Improvements tab is not to be pleted. Control Line Balance Model 46 練習(xí)指南 1. 使用 Excel工作表格 ,看 “目前的時(shí)間 ” 以完成 “Current Takt Time Chart.” 2. 看 “ Current Staffing” 完成 “Skill Matrix” 3. 使用這三個(gè)表重新分配任務(wù)，用同樣的認(rèn)輸和程序在原來的生產(chǎn)線上平衡任務(wù)數(shù)
