TYPES OF PRODUCTIONContinuous-process
production Products that flows in a continuous
stream.Petroleum production, cement production,
steel rolling, paper production, etc.
7
Mass production High volume production of
discrete products with relatively small
variations in products.Automobiles, tv sets,
electronic components, etc.
8
Job-shop production Production of small number
of different discrete products
