Process yield analysis for autocorrelation between linear profiles
In many industrial applications, the quality of a process or product can be characterized by a function or profile. Autocorrelation between profiles is becoming increasingly common due to, for example, on-line data collection with high-frequency sampling. Therefore, the basic assumption of independent profiles for process capability analysis is not valid. This paper aims at evaluating the proce...
متن کاملInvestigating Effect of Autocorrelation on Monitoring Multivariate Linear Profiles
Abstract Profile monitoring in statistical quality control has attracted attention of many researchers recently. A profile is a function between response variables and one or more independent variables. There have been only a limited number of researches on monitoring multivariate profiles. Indeed, monitoring correlated multivariate profiles is a new subject in the fileld of statistical proces...
متن کاملMultivariate adaptive approach for monitoring simple linear profiles
Adaptive sample size and sampling intervals schemes have been widely used to improve the statistical efficiency of Hotelling T control chart in detecting small changes when the quality of a product or a process can be characterised by the multivariate distribution of quality characteristics. In this paper, we design a Hotelling T scheme varying sample sizes and sampling intervals (VSSI-T) for a...

متن کاملPhase II monitoring of multivariate simple linear profiles with estimated parameters
In some applications of statistical process monitoring, a quality characteristic can be characterized by linear regression relationships between several response variables and one explanatory variable, which is referred to as a “multivariate simple linear profile.” It is usually assumed that the process parameters are known in Phase II. However, in most applications, this assumption is viola...
