wances特殊耗時 Actual Cycle Time = The time it takes an operator to plete one cycle of standard work. The longest operator’s actual cycle time tells us how many parts the cell is capable of running 實際周期 =一位操作員完成標準作業(yè)的整個周期的時間。操作員實際最長耗時告訴我們這個單元可以生產(chǎn)的部件數(shù)。 Takt Time Calculation:計算 每日可得操作時間 (秒 ) 總平均每日生產(chǎn)要求 (件數(shù) ) 目標: 實際周期 目標周期 TAKT時間 Labor Efficiency 勞動效率 Labor Efficiency = Standard Direct Labor Hours Actual Spent Hours Standard Labor x Standard Cycle Time (In Hours) x Output Actual Labor x Actual Hours = Productivity Benchmark 生產(chǎn)力參照值 ? Cell F1 單元 F1 – Average Manual Time (MT) seconds 平均手工時間 – Manual time is the time required for an operator to perform the physical tasks for one cycle of operation.(Inspecting, loading/unloading, and gauging) 手工時間是一操作工完成一個操作周期所花在手工操作上的時間 (檢驗,裝卸,檢測等 ) – Takt seconds 理論周期 ? Manual (MT) % of Takt % 手工時間占理論周期的比例 % MT TAKT = 36 = % PRODUCT MIX 混流生產(chǎn) Product Mix Example 產(chǎn)品混合例子 { Product A + B + C = 876 產(chǎn)品 A = 219 = 25% B = 307 = 35% C = 350 = 40% 876 = 100% Total Available Time總共可用時 : 8 hours X 60’= 480’20’(210’ breaks)=460’X60”=27,600” 27600”/876 daily units required = ” Takt Time Total Daily Available Time總每日可用時 Avg. Daily Units Required(A,B,C) 平均每天所需求的件數(shù) TAKT = Target Cycle Time Calculation 目標周期的計算 ? Target Cycle Time = Takt Time Special Allowances ? 目標周期 = TAKE 時間 特殊耗時 – Takt Time = ” – Special Allowances特殊耗時 = 10’ ATPM + 12’ Team Meeting 小組會議 Special Allowances特殊耗時 = 22’ X 60” = 1320” Special Allowance per cycle = 1
