Applications of a new process capability index to electronic industries

Communications in Statistics: Case Studies, Data Analysis and Applications, 2022
The process capability indices (PCIs) are frequently adopted to measure the performance of a process within the specifications. Although higher PCIs indicate higher process “quality,” yet it does not ascertain fewer rates of rejection.

Stage-independent multiple sampling plan by variables inspection for lot determination based on the process capability index Cpk

International Journal of Production Research, 2022
Multiple sampling plan (MSP) has been proved that the sample units required for inspection at each stage are usually smaller than the conventional single or double sampling.

Development of an adaptive sampling system based on a process capability index with flexible switching mechanism

International Journal of Production Research, 2022
The quick-switch sampling system (QSS) and tightened-normal-tightened sampling system (TSS) are efficient schemes for dispositioning a series of lots. However, the QSS mechanism for switching decision rules is too simple to satisfy the requirements of ...

On the confidence intervals of process capability index Cpm based on a progressive type‐II censored sample

Quality and Reliability Engineering International, 2022
This paper is concerned with the process capability index in the case of the progressively type‐II censored sample. In particular, the asymptotic distribution of maximum likelihood estimators of the process capability index is derived and it is used to ...

Determination of modified double sampling plan based on the process capability index

Journal of Statistical Computation and Simulation, 2022
Sampling plans developed based on the process capability indices have great impact in assuring the quality of procured goods since such indices are widely applied in industries to monitor the process quality.

An integrated quick-switch sampling system based on a process capability index for constructing a solid supplier-buyer relationship

International Journal of Production Research, 2021
The quick-switch sampling (QSS) systems based on process capability index (PCI) have been proved to be useful for inspecting processes streaming at a low level of defects because of their small sizes required and dynamic responsiveness to problems ...

Parametric inference of generalized process capability index Cpyk for the power Lindley distribution

Quality Technology & Quantitative Management, 2021
In this article, to estimate the generalized process capability index (GPCI) Cpyk when the process follows the power Lindley distribution, we have used five methods of estimation, namely, maximum likelihood method of estimation, ordinary and weighted ...

Adjustable variables multiple-dependent-state sampling plans based on a process capability index

Journal of the Operational Research Society, 2021
Acceptance sampling plans are practical and economical methods of statistical quality control. In modern manufacturing processes, supplier’s products are produced from continuous-flow manufacturing processes; consequently, the quality of successive lots ...

Finite sample performance of an estimator of process capability index Cpm for the autocorrelated data

Communications in statistics. Simulation and computation, 2021
Process capability index Cpm , sometimes called Taguchi index, is a widely used measure to assess the ability of a process to cluster around the target. In calculating Cpm , it is assumed that the process data are independent, however, in many processes ...

A new probability-based multivariate process capability index

International Journal of Quality Engineering and Technology, 2021
Multivariate process capability indices (MPCIs) MCp, MCpk and MCpm have been proposed in literature to measure multivariate process capability. From a practitioner's view, the intention of this paper is to propose a new probability-based MPCI MSpmk which
