Estimating Process Capability Indices of Multivariate Non-Normal Processes
The capability analysis of production processes where there are more than one correlated quality variables is a complicated task. The problem becomes even more difficult when these variables exhibit non-normal characteristics. In this paper, a new methodology is proposed to estimate process capability indices (PCIs) of multivariate non-normal processes. In the proposed methodology, the skewness...
متن کاملDeveloping New Multivariate Process Capability Indices for Non-Normal Data
Generally, an industrial product has more than one quality characteristic. In order to establish performance measures for evaluating the capability of a multivariate manufacturing process, several multivariate process capability indices have been developed based on the assumption of normality. Quality characteristics of many manufacturing processes in the chemical, pharmaceutical and electronic...
متن کاملBayesian Estimation of Generalized Process Capability Indices
Process capability indices PCIs aim to quantify the capability of a process of quality characteristic X tomeet some specifications that are related to ameasurable characteristic of its produced items. One such quality characteristic is life time of items. The specifications are determined through the lower specification limit L , the upper specification limit U , and the target value T . Maiti ...
متن کاملUnderstanding Process Capability Indices
1. Introduction A process capability index is a numerical summary that compares the behavior of a product or process characteristic to engineering specifications. These measures are also often called capability or performance indices or ratios; we use capability index as the generic term. A capability index relates the voice of the customer (specification limits) to the voice of the process. A ...
متن کاملCapability Indices for Rayleigh Process
Monitoring, control and improvement of quality are important for companies. Process capability indices (PCIs) are tools widely used by the industries to determine the quality of their products and the performance of their manufacturing processes. Classic versions of these indices were constructed for processes whose quality characteristics have a normal distribution. But, many of these ...
