Job shop manufacturing

Job shops are designed to manufacture a wide variety of products with small lot sizes in order to achieve maximum flexibility. Products have usually different operation sequences and operating time for each operation could vary significantly in job shop manufacturing. Products are released to the job shops in batches also called jobs. General purpose machines […]
