Separation between machine job and man job 區(qū)分機器作業(yè)和手動作業(yè) 2. Ensures quality requirements 確保質(zhì)量要求 3. Ensures smooth flow based on Takt time 確?;诠?jié)拍時間的連續(xù)流 Example 1: 例子 1 WIP in the reflow oven for curing with process time 6 min and Takt time 30 sec. 在回流焊爐中固化的 WIP,制程時間 6 min,節(jié)拍時間 30 sec. Standard WIP in the curing oven = Process Time / Takt Time 回流焊爐的標(biāo)準(zhǔn) WIP = 6 min / 30 sec = 12 Pcs 11 What is Standard WIP 什么是標(biāo)準(zhǔn) WIP Example 2: 例子 2 WIP in the tester at backend assembly with process time 60 sec and Takt Time 30 sec. 后段組裝線測試機的 WIP,制程時間 60 sec,節(jié)拍時間 30 sec. Standard WIP in the Test station = 60 sec/ 30 sec 測試工位的標(biāo)準(zhǔn) WIP = 2 pcs ? In other words, Standard WIP in order to fulfill the above 1), 2), 3) functions, It is the pulsory WIP in the machine / process before establish standard work for the process. 換句話說,標(biāo)準(zhǔn) WIP能夠確保上述 1),2),3)達成,在建立標(biāo)準(zhǔn)作業(yè)前,標(biāo)準(zhǔn) WIP是機器和制程強制的 WIP。 Key Note from Sensei: 老師的重要提示: ? To understand the above WIP definitions, go to The Genba and perform your own work towards Establishing the right WIP quantities. This is the Only way you can understand the definition. 要理解 WIP定義,你需要去到現(xiàn)場在工作中實踐正確的 WIP數(shù)量。 ? Standard WIP is the Ideal or Should be conditions for WIP 標(biāo)準(zhǔn) WIP是理想 WIP或者是 WIP的應(yīng)有狀態(tài)。 As such the Process Takt Time Calculation as following: 制程節(jié)拍時間計算如下: = Takt Time X Product Up x Process Up X Number of Line = 2 sec X 6 products per panel X 4 Panel per pallet X 2 Lines = 96 sec 8 What is Standard WIP 什么是標(biāo)準(zhǔn) WIP Various types of WIP in our manufacturing process 生產(chǎn)過程中存在各種類型的 WIP 1. Standard WIP 標(biāo)準(zhǔn) WIP 2. Process WIP 制程 WIP 3. Process To Process WIP 制程與制程間 WIP 4. Station To Station WIP 工位與工位間 WIP 9 What is Standard WIP 什么是標(biāo)準(zhǔn) WIP ? WIP means INVENTORY. INVENTORY is Basically ‘bad’. WIP就是庫存。如果同時有 2 條生產(chǎn)線生產(chǎn),制程的節(jié)拍時間則為 96 秒。 7 How to start the Takt Time Calculation Based On Product and Process Design怎樣根據(jù)產(chǎn)品和制程設(shè)計計算節(jié)拍時間 Scenario 1: Product design is 6 pcs per one PCB panel. The Process Takt Time will be every 12 second a panel. Besides, your process design is using a pallet to place 4 panels, then your Process Takt Time is 48 second a pallet. If 2 line running, process Takt time will be 96 sec. 情節(jié) 1:產(chǎn)品設(shè)計為每塊 PCB板由 6 塊小板組成,節(jié)拍時間是每塊 PCB板 12 秒 。 ?Takt Time calculation shall display all the variable and units to make clarity to all. 計算節(jié)拍時間時要顯示所有變量及單位,便于大家理解。 No Std Work means no Kaizen … Std Work is the Mother of all Kaizen 沒有標(biāo)準(zhǔn)作業(yè)就沒有改善 …… 標(biāo)準(zhǔn)作業(yè)是改善之母 5 How to start the Takt Time Calculation Based On Customer Demand 怎樣根據(jù)客戶需求計算節(jié)拍時間 ? Step 1: Calculate Takt time Based on Customer Demand 第一步:根據(jù)客戶需求計算節(jié)拍時間 ? Example 例如 : ? Customer Demand per Month 792K. Working hour per day is 22 hours, 20 days a month. 客戶每月需求量是 792K。 Type 2 : Standard Work to support man (90%) machine (10%) bination task. 類型 2:標(biāo)準(zhǔn)作業(yè)適用于 90%手動作業(yè) 和 10%機器作業(yè)的組合作業(yè)方式 。 生產(chǎn)周期減半 ?

Lead Time : X 189。 面積減半 Goal : Add Value Eliminate Waste … Relentlessly for Our Customers 目標(biāo) : 減少浪費 創(chuàng)造價值 全心全意為客戶服務(wù) ? ETE (End to End) Productivity Improvement 端到端 (從頭到尾 )產(chǎn)能提高 ? ETE Zero Defect (Quality, TPM, OEE etc.) 端到端 (從頭到尾 )零缺陷(質(zhì)量,全面生產(chǎn)維護,全局設(shè)備利用率等) ? Inventory Reductions 降低庫存 ? Lead Time Reductions 縮短生產(chǎn)前置期 ? Crew Size Optimization 優(yōu)化人員數(shù)量 ? Space Reduction 減少 使用面積 Double the Good 好的加倍 Halve the Bad 壞 的減半 Double the Speed 改善速度加倍 Kaizen Workshop Goal 改善目標(biāo) No Money 不投入更多金錢 No Space 不占用更多面積 No Manpower 不使用更多人力 2 Standard Work Standard Combination Sheet 標(biāo)準(zhǔn)化作業(yè) 標(biāo)準(zhǔn)作業(yè)合并表 1) Standard work defined 標(biāo)準(zhǔn)作業(yè)定義 a) Takt time defined 節(jié)拍時間的定義 b) Work sequence defined 工序的定義 c) Standard WIP defined 標(biāo)準(zhǔn)在線庫存定義 d) Cycle time defined 周期時間定義 e) No of operators defined 操作員數(shù)量的定義 f) Safety 安全性 g) Multi skill 多技能 2) Standard work bination sheet defined 標(biāo)準(zhǔn) 作業(yè)合并表定義 a) Manual time 手動時間 b) Auto time 機器 (自動 )時間 c) Walking time 走動時間 d) Waiting time 等待時間 3) Is the Quality check legend defined on each process on std work sheet? 標(biāo)準(zhǔn)作業(yè)合并表上,有定義每個流程中的品質(zhì)管控的關(guān)鍵點嗎? 3 Key Elements 3項 關(guān)鍵要素 3 3 Types of Standard Works 3種標(biāo)準(zhǔn)作業(yè) Ta k t Ti m e節(jié)拍時間S e qu e nc e順序S t a nd a r d W I P標(biāo)準(zhǔn)在制品1 YFe w很少Y Y Y N S W C S S M T2Fe w很少Y Y Y Y NW o r k L o a d L e v e
