Fuzzy Evaluation Model of Process Improvement Capability with Costs Consideration
Applied Sciences, 2021 The Taguchi capability index, which reflects the expected loss and the yield of a process, is a useful index for evaluating the quality of a process. Several scholars have proposed a process improvement capability index based on the expected value of the

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.

New process capability index using Taguchi loss functions [PDF]
, 2009 Classic process capability indices such as Ca, Cp and Cpk are well-known process capability indices, which are using widely. Since, process capability indices predict the capability of a process, they must have a significant relation with rate of rejects

POINT ESTIMATION OF THE PROCESS CAPABILITY INDEX C(pk) [PDF]
, 1995 In this paper point estimation of the process capability index C(pk) is considered. In order to improve on the natural estimator, a simple alternative estimator is proposed and its mean square error is evaluated ...
