文档介绍：八大浪费介绍 ——与浪费开战
Prepared by Fisher Chan ,2007 Flextronics Manufacturing System (FMS)
Over Processing 不必要的过程
Transportation 运输
Motion/Movement
运作
Defects 缺陷
Take all FOUR
I need ONE!
Over Production 过量生产
Inventory
库存
Waiting
等待
7 Types of Waste 七大浪费
运输: 人员,物料和消息的低效流动
工厂布局差
流程效率低
库存多
产品在运输过程中遭受潜在损害
资源成本增加
举例:
任何连续作业中断的地方
材料储存不符用点的地方
丰富的材料处理装置:运输带扣,铲车,码垛车等
背离直接的材料流程
解决方法:
减少不必要的生产步骤-通过适当的直接设计去除复杂流程
使用看板拉动系统
去除/减少WIP库存区
采用蜂窝状生产模式
Transportation 运输
Transportation
Inefficient movement of people, materials and
information in anization
Poor layout
Inefficient “flow”
Carrying large inventories
Exposes product to potential damage/loss during transportation
Increases cost to hire resources to ferry
Examples:
Anywhere sequential operations are uncoupled
Where material storage is not adjacent to point-of-usage
Abundance of material handling equipments: conveyors, forklifts, pallet trucks, etc.
Deviation from straight-through material flow process
Solutions:
“Shrink the footprint”- eliminate spaghetti flows via proper line design
Use Kanban pull systems
Eliminate or reduce WIP Inventory storage locations
Introduce Cellular Manufacturing
Inventory 库存
库存: 所有超出流程的供应
常常是”过量生产”的结果
以防万一逻辑
工作量不平衡
行程安排不平衡
供应商不可靠<br****惯
举例:
成品库存
半成品库存
物料盘存
备料库存
解决方法:
根据客户订单生产
看板拉动系统
去除库存区
终止不必要的库存计划
Inventory
Any supply in excess of one-piece flow
Often the result of “Overproduction”
Just in case logic
Unbalanced workload
Unleveled scheduling
Unreliable suppliers
Habit
Examples:
Finished Good Inventory
Work In Process Inventory
Supplies Inventory
Staged or “kitted” Inventory
Solutions:
Make to Customer Order
Kanban Pull System
Eliminate Inventory Storage Areas
Stop Planning for Unnecessary Inventory
Motion 动作
动作: 生产过程中不必要的荣誉,工作或机器的移动
工厂布局差
工作场所缺乏组织性
缺乏标准化,工作方法不一致
增加作业员疲劳导致其他浪费,如:缺陷
工效问题对健康的影响,如:重复性动作伤害,等
举例:
浪费时间寻找物品,等
额外动作
材料与工作站设计不合理
解决方法:
5S anization
Point-of-Usage Storage
工作站设计
Examples:
Time spent away from workplace looking
