An Efficient Phase I Analysis of Linear Profiles with Application in Photo-Voltaic System
( Springer Verlag , 2019 , Article)In many manufacturing industries, quality of an item depends on different characteristics and their relationship may be modeled by profiles. For instance, in photo-voltaic (PV) system, output voltage is dependent on the ... -
An ensemble neural network framework for improving the detection ability of a base control chart in non-parametric profile monitoring
( Elsevier , 2022 , Article)Profile monitoring is a challenging issue in statistical process control (SPC). It aims to use a functional relationship between a response variable and one or more explanatory variable(s) to summarize the quality of a ... -
An Improved Control Chart for Monitoring Linear Profiles and its Application in Thermal Conductivity
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)In most of the manufacturing processes, we encounter different quality characteristics of a product and process. These characteristics can be categorized into two kinds; study variables (variable of interest) and the ... -
An attribute control chart for the inverse Weibull distribution under truncated life tests
( Elsevier Ltd , 2022 , Article)Statistical Process Control (SPC) is applied to monitor production processes in order to discover any problems or issues that may arise during the production process and to help in finding solutions for these issues. In ... -
Enhancing the detection ability of control charts in profile monitoring by adding RBF ensemble model
( Springer , 2022 , Article)While numerous contributions and applications have been extended in profile monitoring, little attention has been paid to employing machine learning techniques in development of control charts. In this paper, a novel control ... -

A Novel Simulation-Based Adaptive MEWMA Approach for Monitoring Linear and Logistic Profiles
( IEEE , 2021 , Article)As a common approach in the development of control charts in Statistical Process Control (SPC), an industrial process is monitored with one or more quality characteristics using their corresponding distributions. Note ... -
Run Rules-Based EWMA Charts for Efficient Monitoring of Profile Parameters
( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)In usual quality control methods, the quality of a process or product is evaluated by monitoring one or more quality characteristics using their corresponding distributions. However, when the quality characteristic is ... -
Shrinkage estimates of covariance matrices to improve the performance of multivariate cumulative sum control charts
( Elsevier Ltd , 2018 , Article)Multivariate cumulative sum control charts require knowledge of the in-control process covariance parameters. Here, we show that the performance of the multivariate cumulative sum control charts for individual-observation ...
