.3.The Organization of Production System A production system is usually divided into basic units,e.g.workshop,manufacturing cell, and working team,and all these units can be organized on one of the following three basic principles: ·Process focused ·Product focused Group technology(GT)
1.3. The Organization of Production System A production system is usually divided into basic units, e.g. workshop, manufacturing cell, and working team, and all these units can be organized on one of the following three basic principles: • Process focused • Product focused • Group technology (GT)
Principle of Process focused part3 partl 一·→ part2 Process focused part2 part1 (a) part3 Principle of process focused:organize the production units according to a production process kind(Turning,milling, grinding,drilling,etc). Within one production unit,the same type of workers complete the same processes using the same type equipments. e.g.machining workshop:lathe section,and drill section
Principle of Process focused Process focused • Principle of process focused : organize the production units according to a production process kind (Turning, milling, grinding, drilling, etc). • Within one production unit, the same type of workers complete the same processes using the same type equipments. e.g. machining workshop： lathe section, and drill section
⑧ Principle of Process focused high equipment utilization rate an employee do some fixed operations Advantages units have high flexibility to produce various of products long conveying routes ·great amount WIP Disadvantages WIP needs long waiting time frequent cooperation and interdependency among production units
Principle of Process focused • high equipment utilization rate • an employee do some fixed operations • units have high flexibility to produce various of products Advantages • long conveying routes • great amount WIP • WIP needs long waiting time • frequent cooperation and interdependency among production units Disadvantages
Principle of Product focused partl B A partl Product part2 part2 focused part3 part3 (b) Principle of product focused:the production unit is organized according to a product kind or a part or a component kind)
Principle of Product focused Product focused Principle of product focused: the production unit is organized according to a product kind ( or a part or a component kind )
Principle of Product focused part1 A B partl Product part2 part2 focused part3 B part3 (b) Within one production unit,one product's production(all processes)is completed by different type workers using different type equipments It can also be called as closed-production-unit.e.g automobile assembling line,TV assembling line
Principle of Product focused • Within one production unit, one product’s production( all processes) is completed by different type workers using different type equipments • It can also be called as closed-production-unit. e.g. automobile assembling line, TV assembling line. Product focused
Principle of product focused 。Advantages: the material handling distance in production process can be reduced greatly the WIP inventory can be reduced greatly. can use productive and automatic organization mode-production line. the cooperation among production departments can be reduced,and hence management can be simplified
Principle of product focused • Advantages: the material handling distance in production process can be reduced greatly the WIP inventory can be reduced greatly. can use productive and automatic organization mode—production line. the cooperation among production departments can be reduced, and hence management can be simplified
Principle of product focused Disadvantages low equipment utilization rate; the whole production unit can be influenced once an equipment breakdown; low production flexibility
Principle of product focused • Disadvantages low equipment utilization rate; the whole production unit can be influenced once an equipment breakdown; low production flexibility
Group Technology Group Technology (Manufacturing cell,flexible manufacturing system)-allocate different equipment into a production cell to work on a product family that have similar shapes and process requirements. Within one cell,the production of a product family can be completed by different type workers using different type equipment
• Group Technology (Manufacturing cell, flexible manufacturing system)- allocate different equipment into a production cell to work on a product family that have similar shapes and process requirements. • Within one cell, the production of a product family can be completed by different type workers using different type equipment.
