TYPES OF MANUFACTURING SYSTEM
Production Quantity Plant Layout
• Total Work System :Make according to order,
limited,unique slow to complete
e.g. jewelry, yacht ,luxury car.
• Group System :
Make in groups / needs a large
storage space.
e.g. furniture, paint, books
• Mass System :
Components assembled in sequence,repetitive, automatic. e.g.
television,car, canned food
• Location of Product :Equipment is arranged according to
location where product made. e.g.
car, motorcycle, mobile phone
• Function of Equipments
Equipment is arranged according to
its function.
e.g. grinding, cutting, drilling .
• According to Product :
Equipment is arranged according to
the method of production.
e.g. packaging, boiling, painting.
