Implementing process capability indices for a complete product
نویسنده
چکیده
This study develops a novel procedure for measuring the process capability indices of a complete product with several quality characteristics. The p-values of the estimators of Cpl , Cpu , and Cpp, so that the process works at least 100(1−α)% of the time, are provided. An evaluation checklist is also given to determine whether the process’s potentiality and performance meet consumers’ expectations.

Multivariate process capability indices on the presence of priority for quality characteristics
Multivariate Process Capability Indices (MPCI) show how well a manufacturing process can meet specifica-tion limits when quality characteristics enclose a relative correlation. Process capability is an important and commonly used metric for assessing and improving the quality of a production process. When quality charac-teristics of a product are correlated then an attractive comes close to MPC...
متن کاملEstimating Process Capability Indices Using Univariate g and h Distribution
Process capability of a process is defined as inherent variability of a process which is running under chance cause of variation only. Process capability index is measuring the ability of a process to meet the product specification limit. Generally process capability is measured by 6 assuming that the product characteristic follows Normal distribution. In many practical situations the product ...
متن کاملEstimating process capability indices using ridge regression
Process capability indices show the ability of a process to produce products according to the pre-specified requirements. Since final quality characteristics of a product are usually interrelated to its previous amounts in earlier workstations, one need to model and consider the relationship among them to assess the process ca-pability properly. Hence, conducting process capability analysis in ...
متن کاملIntroducing Triangular Fuzzy Process Capability Indices to Evaluate Performance of Continuous Production Process
Process capability indices (PCIs) can be used as an effective tool for measuring product quality and process performance. In classic quality control there are some limitations which prevent a deep and flexible analysis because of the crisp definition of PCA‟s parameters. Fuzzy set theory can be used to add more flexibility to process capability analyses. In this study, the fuzzy X ba and MRx ba...
متن کاملProcess Capability Index for Logistic Regression Profile Based on Spmk Index
Profile is a relationship between a response variable and one or more independent variables which can describe quality of a process or a product. On the other hand, for an in-control process, capability indices are criteria for the process quality improvement that allows to meet customers’ expectations. Despite a considerable number of applications and monitoring methods already proposed for pr...
