VSM-Chinese--价值流程图绘制方法.pptVIP

Introduction 介绍 “Whenever there is a product for a customer, there is a value stream.只要有客户产品的地方，就会有价值流程.The challenge lies in seeing it挑战就在于发现它. Introduction to Lean What is Lean? The 7 Wastes T = Transport Why Do Value Stream Mapping?为什么要绘制价值流程图? Steps for Value Stream Mapping价值流程图的绘制步骤 Step 1: Select a Product Family第一步:选择一类产品 Step 2: Create the Current State Map第二步: 绘制出现状图 代表性数据收集及计算 Drop Off Rate (DOR) 有效作业时间 Changeover Time (C/O) 转换时间 Availability (Uptime) 可用性(运行时间) Production Batch Size 一批生产的数量 Number of Operators 操作者数量 Pack Size 一个包装里的数量 Available Working Time - # shifts time 可用的工作时间-多少班以及时间 Scrap Rate 废品率 Product Variations (i.e. L, R) 产品的变化种类 (就是: 左, 右) Rusty’s Wrench FactoryRusty扳手工厂Case Study案例分析 Multiple Part Flows 多零件的流程 Rusty’s wrench factory is simplified to better understand the VSM principles. Rusty扳手工厂是简单化有利于更好理解VSM原理. Many operations have multiple part flows that merge at some point (ie-assembly). 许多运作其实有多个零件流在某一点(装配)上汇合. Draw these flows over one another on your map. 将这些流程一个个依次画在你的图上.
