6、出? Most repeatable rate demonstrated by the production team (usually results in a % of allowable time above cycle time)由生产小组得出的重复最多的速率(通常引起周期时间的允差百分比),Basic Definitions 基本定义,Production Pacing_Lvl1_SHW_E_Oct 2003.ppt,7,In most cases are the following True or False and why:在通常情况下, 下列说法是否正确, 为什么? Cycle
7、 Time = Target Rate周期 = 目标速率 Takt Time = Cycle Time节拍 = 周期 Target Rate = Takt Time目标速率 = 节拍,Basic Definitions 基本定义,Production Pacing_Lvl1_SHW_E_Oct 2003.ppt,8,Example: Cycle Time / Target Rate / Takt Time 例: 周期 / 目标速率 / 节拍 Takt Time & Target Rate节拍&目标速率Cycle Time周期,Basic Definitions 基本定义,Production
8、Pacing_Lvl1_SHW_E_Oct 2003.ppt,9,What is Pitch?什么是节距?Unit of time required to produce one customer standard pack and is used to pace withdraw and replenishment of the line.生产一个客户标准包的单位时间, 并用来确定生 产线产品的提取和补充速度。How do you calculate it?如何计算?Customer Std Pack X Takt Time客户标准包 X 节拍,Basic Definitions 基本定义,

Calc: (Qty required of part A) / (Total qty required)公式: (零件A需要的数量) / (需要的总数量),Basic Def
10、initions 基本定义,Production Pacing_Lvl1_SHW_E_Oct 2003.ppt,11,What is the Replenishment Route?何为补充路线? Standard Time used to withdraw and replenish the line 用于提取产品和补充生产线的标准时间 How do you come up with the time required?如何提出所需要的时间? Should do elemental time studies of the route to determine the longest tota
11、l route time required 应该对路线进行自然时间研究, 来确定所需的最长路径时间,Basic Definitions 基本定义,Production Pacing_Lvl1_SHW_E_Oct 2003.ppt,12,What is Pace?何为速度? The predetermined frequency at which the line will be measured, insuring pitch is met consistently throughout a given time period.预先确定的生产线的频率, 确保在一个给定的时期内能够始终如一地达到
12、节距 How can Pitch and the Route Time be used together to determine the Pace?节距和路径时间怎样被结合起来决定速度? Example: Pitch = 5 min; Route = 9.5 min; Therefore the route is paced at 10 min (2 pitch pace)例: 节距 = 5分钟, 路径 = 9.5分钟, 因此路径被定为10分钟(2个节距的速度) Example: Pitch = 30 min; Route = 15 minutes; Therefore the route
13、is paced at 15 min (.5 pitch pace)例: 节距 = 30分钟, 路径 = 15分钟, 因此路径被定为15分钟(.5个节距的速度),Basic Definitions 基本定义,Production Pacing_Lvl1_SHW_E_Oct 2003.ppt,13,Simulation Time 模拟时间,Production Pacing_Lvl1_SHW_E_Oct 2003.ppt,14,Calculation: % Penetration 计算: 渗透百分比,Calculate the % Penetration for each part in thi
