Gauge Imprecision and Process Capability Analysis
نویسنده
چکیده
Alternative definitions of Process Capability Indices (PCIs), based on different approaches, have been proposed in literature. Most of the research works related to Process Capability Indices assume no gauge measurement errors. However, in industrial applications, despite the use of highly advanced measuring instruments, account needs to be taken of gauge imprecision. The aim of this paper is first to present the state of the art on univariate and multivariate capability indices research, encouraging the use of this important technique for process control and quality improvement and then, to present a review on the recent researches on the effects of measurement errors, showing that measurement errors can alter the results of process capability analysis.

The Effect of Gauge Measurement Capability and Dependency Measure of Process Variables on the MCp
It has been proved that process capability indices provide very efficient measures of the capability of processes from many different perspectives. These indices have been widely used in the manufacturing industry for measuring process reproduction capability according to manufacturing specifications. In the past few years, univariate capability indices have been introduced and used to characte...
متن کاملFuzzy Gauge Capability (Cg and Cgk) through Buckley Approach
Abstract—Different terms of the Statistical Process Control (SPC) has sketch in the fuzzy environment. However, Measurement System Analysis (MSA), as a main branch of the SPC, is rarely investigated in fuzzy area. This procedure assesses the suitability of the data to be used in later stages or decisions of the SPC. Therefore, this research focuses on some important measures of MSA and through ...
متن کاملMeasuring process capability based on CPK with gauge measurement errors
The well-known process capability index CPK has been popularly used in the manufacturing industry for measuring process reproduction capability. Existing research papers related to CPK have assumed with no gauge measurement errors. Unfortunately, such assumption does not reflect real situations accurately even with highly sophisticated advanced measuring instruments. Conclusions drawn from proc...
متن کاملProcess Capability Analysis in the Presence of Autocorrelation
The classical method of process capability analysis necessarily assumes that collected data are independent; nonetheless, some processes such as biological and chemical processes are autocorrelated and violate the independency assumption. Many processes exhibit a certain degree of correlation and can be treated by autoregressive models, among which the autoregressive model of order one (AR (1))...
