![Page 11: Computer Integrated Manufacturing](https://reader033.vdocument.in/reader033/viewer/2022061120/546c6d16b4af9fbc568b4b18/html5/thumbnails/11.jpg)
1) Low Quantity Production
• job shop type, customized product, large variety of product type
• ex) space capsules, airplane, special purpose machine
• maximum flexibility
![Page 12: Computer Integrated Manufacturing](https://reader033.vdocument.in/reader033/viewer/2022061120/546c6d16b4af9fbc568b4b18/html5/thumbnails/12.jpg)
