【正文】 ift, calculate the number of assemblers/processors and average takt time it will take to satisfy the demand. ? Approach 2 – DaytoDay Scheduler: ? Given the inputs of average productivity, assembly/processing time, number of assemblers/processors, and desired output (demand), calculate the hours per shift and takt rate it will take to satisfy the demand. ?What’s the difference? ? Long Term Planner allows management to understand staffing increments based upon some forecasted demand on a line by line basis. ? DaytoDay scheduler allows line supervision to calculate process parameters (takt rate, hours to work) based on the number of units to process and the number of people who show up to work that day. 17 Line Balance Model Control 線平衡步驟 ?兩種不同的方法 : ?方法 1 – 長期計劃員 : ? 作出平均投入生產(chǎn)率、裝配 /加工時間、及預計的產(chǎn)量（需求），每班的時間，計算裝配工 /操作工的數(shù)量，及滿足需求所花的平均時間。 ?區(qū)別是什么 ? ?長期計劃員允許管理來了解在以生產(chǎn)線為基礎上的需求預測而增加員工。 18 Line Balance Model Measure Analyze Control Improve Lean Six Sigma Approach 1 Long Term Planner Measure Analyze Control Improve Lean Six Sigma 途徑 1 長期計劃員 Control Input 1.
