A process capability index for zero-inflated processes
International Journal of Engineering, Science and Technology, 2022 The proportion of zero defect (ZD) outputs is as an integral characteristic of a zero-inflated (ZI) process or high quality process. Different ZI processes can almost equally satisfy the same USL of number of defects but they can produce substantially different proportions of ZD products.
