Post the map in area that is clearly visible to all work group members on a continuous basis.
future state value stream map
Measurements :衡量指标
*前置时间天数是以库存依據顾客需求在各作业間， 计算前置时间必须从制程浪费消除改善
total Cost
*工作小组未来状况对策绩效必须由改善数据反应
The effectiveness of work group future state actions should be reflected by an improvement in these metrics
价值流图析
*价值流图析是一种完整且有系统性的方法
现状价值流图
Current state value stream map
一个现状价值流图是为完整价值流目前存在的视觉 描述。包含物料，产品，即咨询流
A current sate value stream map is the depiction of the complete value stream as it presently exists. the map inclides material, product, and information flow
Lead time in days is calculated by dividing inventory by customer requirements for one day for each operation, lead time should
improve as waste is eliminated from the process
*价值流图析可以帮助你发现生产制程中 的浪费的根源
*价值流图可以为生产过程提供共同语言 *价值流图可显示讯息流与材料流的联系 *没有其他工具能做到此项功能
价值流图析基本功能
*价值流图是为实现精实生产的蓝图以作 为改善实施计划的基础
*如果要设计一个新的生产制程或者要改 变一个现有的价值流就将精实生产理论 概念与技术实务结合
*绘制咨询流
Draw the information flow
*绘制时间线描述前置时间，表示出有附加值 与无附加值时间
Draw a timeline depicting the lead time, showing value add and non-value add time
Current state mapping for a value stream
虽然关注在生产制造，也可以用在描述非生产活动。
Although the focus is on the manufacturing, the map could also be used to depict non-manufacturing activities
现状价值流图
Current state value stream map
评估现状 Assessing the current situation
价值流图分析第一步骤是评估现实状况以制 作现状图
The first in value stream mapping is assessing the current situation by creating a current state map

课程目标 Objectives
在完成此一课程你将能
At the end of this section, you will be able to :
*定义期间价值流及价值流图分析
Define the terms Value stream and valurent state map
Value stream mapping
Futures state map
未来价值流图 future state value stream map
未来价值流图是一目视可描述改善對策目标包 含物料，产品，及咨询流
A future state value stream map is visual depiction of the goal of improvement actions, the map includes material, product, and information flow
*使用价值流图析之意义是可在巨观的大范 圍下作业。亦可拘於局部性.區域性.或個別 性的作業.
*因此他是可进行全面整体性而不仅是最佳 化个别部分。
价值流图析
*一个价值流图析是指归集一产品在其生 产过程中所有的活动：包括哪些有增加 附加價值及没有增加价值的活动。
*价值流图析将是包含有附加值作业与无 附加值作业调查检讨，用以改善制程提 升整体生产力的一项系统手法
未来价值流图析步骤
future state value stream mapping
*着手以现状价值流图鉴别消除浪费机会
Begin with the current state value streams map, use
the map to identify opportunities to eliminate waste. *确认顾客需求/takt time
未来价值流图析步骤
future state value stream mapping
*使用工具如流程分析以协助分析及鉴别浪费降低的机 会
Use tools, such as process flow analysis,to help analyze and identify waste reduction opportunities.
*确认在生产鍊单一点（制程速率点）可排生产计划
Identify one single point in the production chain (the pacemaker process “)where you will schedule production
*张贴价值流图在作业区给全部工作人员清楚目视為持 续改进的基础
价值流图析
*价值流是为产品已当前通过其基本生产 过程所进行的全部活动，可分成
.从原材料到产品交到顾客手中
“生产流”
.从概念到投产
“设计流”
价值流图析
*从顾客到供应商跟随产品的生产反向路 径将材料流与讯息流以代表图形仔细绘 出每個过程以便于了解掌握制程中的
(关键问题)
*分析检讨，关键问题，提出改善对策后， 再次绘制一期望的，未来状態的价值流 图，作为目标蓝图及执行改善活动

何謂精實製造(Lean Mfg)
• 它是什麼?
– 是一種在價值流(value stream)中藉由排除浪費
以提昇流動性，使其能獲致更短的前置時間， 從而提供高品質、低成本的製造哲學
– 由產品開發、程序工程、營運管理及企業總管
理作業等所組成的一整合性系統，其能為顧客 提供價值及帶給人們尊嚴
*提供流動视觉的描述（以）用作零件制程程序的决策
Provides a visual depiction of flow use as part of the decision making process
*在价值流中以提供鉴认七大浪费缘由
Allows for identification of the sources of the seven wastes in the value stream
*验证咨询流与材料流的關连性
Demonstrates the linkage between information flow and material flow
*通过价值流以作为工厂发展改善流程基础与消除浪费
Becomes the basis for developing a plan for improving flow throughout the value stream
A value stream is all of the actions required to change raw materials into a product delivered to the customer
价值流图是什么
What is Value Stream Map
定义 Definition
现状价值流图
Current state value stream map
*选择一产品或产品族 Choose a product or product family *描述顾客需求 Depict the customer requirements *反向跟随产品从交货，生产作业，到原料入厂
Follow the flow of the product from shipping, working backwards to the where raw materials arrive in the plant
*附加值时间秒数是由作业时间计算，如变更外形 安装， 或产品修饰，附加价值时间将相同于现在与未来状况除 非制程被变更
Value-add time in seconds is calculated by timing the operation as it changes form, fit, or finish of the product. value add time will be the same in both the current and future sate unless process is changed
. 一个目视化以描述整体价值流， 包含原材料产品及咨訊流分析图
