andard WIP for each station is 1pc. 改善前,插件拉的制程 WIP=9 pcs。 ? However, before you fully achieved Standard WIP Quantity, you might need to go through various stages to understand your process Muda and bottle neck 然而,在完全達(dá)到標(biāo)準(zhǔn) WIP數(shù)量前,你需要經(jīng)過(guò)不同的階段了解制程中的浪費(fèi)和瓶頸。 Scenario 2: If Top and Bottom product running on same line at the same time, Takt time shall be half = 48sec 情節(jié) 2:如果正反面產(chǎn)品同時(shí)在一條生產(chǎn)線生產(chǎn),節(jié)拍時(shí)間則為一半, 48秒。 sec 2792 ,0001,58 4,00 0pcs 792 ,000s 360 0 x days 20 x Hou rs 22 Deman d Custome r Time AvailableTime Takt????客戶(hù)需求有效時(shí)間6 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(jì)計(jì)算節(jié)拍時(shí)間 Step 2: Calculate Process Takt time Based on Product and Process Design 第二步:根據(jù)產(chǎn)品和制程設(shè)計(jì)計(jì)算節(jié)拍時(shí)間 Based on Step 1, Takt Time is 2 second to produce 1 pcs. 根據(jù)步驟 1,節(jié)拍時(shí)間是每 2 秒生產(chǎn) 1 件產(chǎn)品。 Type 3 : Standard Work (also called as Work Standard) to support task carried out once signal is triggered. 類(lèi)型 3:標(biāo)準(zhǔn)作業(yè)(也叫做作業(yè)標(biāo)準(zhǔn))適用于當(dāng)信號(hào)產(chǎn)生時(shí)才去執(zhí)行相應(yīng)任務(wù)的作業(yè)方式 。 庫(kù)存減半 ?

Step 1: Calculate Takt time Based on Customer Demand 第一步:根據(jù)客戶(hù)需求計(jì)算節(jié)拍時(shí)間 ? Example 例如 : ? Customer Demand per Month 792K. Working hour per day is 22 hours, 20 days a month. 客戶(hù)每月需求量是 792K。 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(jì)計(jì)算節(jié)拍時(shí)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(jì)為每塊 PCB板由 6 塊小板組成,節(jié)拍時(shí)間是每塊 PCB板 12 秒 。 As such the Process Takt Time Calculation as following: 制程節(jié)拍時(shí)間計(jì)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(guò)程中存在各種類(lèi)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(kù)存。 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(chǎng)在工作中實(shí)踐正確的 WIP數(shù)量。改善后插件拉制程WIP=3pcs。計(jì)算如下: Takt Time = 30sec Changeover Time = 5 min 30sec Process A Process B pcs 10sec 3060sec x 5min WIPPTP ???15 Takt Time 節(jié)拍時(shí)間 Cycle time Takt time ( 1 Station Process ) C/TTakt Time (1個(gè)工位) Cycle time than takt for single process (2 same stations needed) C/TTakt (需要2個(gè)相同工位 ) TAKT Time = 20s 10 20 30 40 Machine/Process A : St. 1 Machine/Process A : St. 2 Note注 : CT TT : No additional Machine/Man needed 不需要額外的機(jī)器 /人員 CT TT : Additional Machine/Man needed 需要額外的機(jī)器 /人員 It can be used to calculate 節(jié) 拍 時(shí)間 可以 計(jì) 算 ?
