A General Multivariate Bayesian Process Capability Index
نویسنده
چکیده
Process capability analysis is designed to estimate the proportion of parts that do not meet engineering requirements in a stable production process. In this paper, we review and criticize the capability indices typically used in industry for this purpose, and propose a general multivariate Bayesian capability index which contains the conventional index as a limiting case. We further derive its analytical expression under standard assumptions, discuss numerical approximations, and illustrate the theory with some examples.

Taguchi Design optimization using multivariate process capability index
The Taguchi method is a useful technique to improve the performance of products or processes at a lower cost and in less time. This procedure can be categorized in the static and dynamic quality characteristics. The optimization of multiple responses has received increasing attention over the last few years in many manufacturing organizations. Several approaches dealing with multiple static q...
متن کاملOn the multivariate process capability vector in fuzzy environment
The production of a process is expected to meet customer demands, specifications or engineering tolerances. The ability of a process to meet these expectations is expresed as a single number using a process capability index. When the quality of the products relates to more than one characteristic, multivariate process capability indices are applied. As it is known, in some circumstances we are ...

Acceptance sampling plan is a method to make decision on either accepting or rejecting a specific lot or more generally to inspect the quality of products that can be used by different methods. Along with this, one suitable measure to improve manufacturing processes is to analyze process capability indices. These indices have many applications in production environments. In this paper, a repeti...
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 ...
