چکیده

in some statistical process control applications, quality of a process or product can be characterized by a relationship between a response and one or more independent variables, which is typically referred to a profile. in this paper, polynomial profiles are considered to monitor processes in which there is a first order autoregressive relation between the error terms in each profile. a remedial measure is first proposed to eliminate the effect of autocorrelation in phase-іі monitoring of autocorrelated profiles. then, three methods are employed to monitor polynomial profiles where their performances are compared using the average run length criterion.

Monitoring and Change Point Estimation of AR(1) Autocorrelated Polynomial Profiles

In this paper, a remedial measure is first proposed to eliminate the effect of autocorrelation in phase-ІІ monitoring of autocorrelated polynomial profiles, where there is a first order autoregressive (AR(1)) relation between the error terms in each profile. Then, a control chart based on the generalized linear test (GLT) is proposed to monitor the coefficients of polynomial profiles and an R-c...

Isotonic Change Point Estimation in the AR(1) Autocorrelated Simple Linear Profiles

Sometimes the relationship between dependent and explanatory variable(s) known as profile is monitored. Simple linear profiles among the other types of profiles have been more considered due to their applications especially in calibration. There are some studies on the monitoring them when the observations within each profile are autocorrelated. On the other hand, estimating the change point le...

Phase II monitoring of autocorrelated linear profiles using linear mixed model

In many circumstances, the quality of a process or product is best characterized by a given mathematical function between a response variable and one or more explanatory variables that is typically referred to as profile. There are some investigations to monitor autocorrelated linear and nonlinear profiles in recent years. In the present paper, we use the linear mixed models to account autocorr...

Phase II Monitoring of MA (1) Linear Profiles

Recently, monitoring quality of a process or product that is characterized by a function or profile is becoming more popular. Many applications are shown for profile monitoring. Most existing control schemes, which have been suggested for profile monitoring in the literatures, consider the independence assumption of observation within profiles. However, in certain situation, this assumption can...
