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 enhanced nonparametric EWMA sign control chart using sequential mechanism
( Public Library of Science , 2019 , Article)Control charts play a significant role to monitor the performance of a process. Nonparametric control charts are helpful when the probability model of the process output is not known. In such cases, the sampling mechanism ... -
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 adaptive EWMA control chart for monitoring time between events with application in health sector
( John Wiley and Sons Ltd , 2023 , Article)Nonconforming events rarely occur in high-quality processes, and the time between events ((Formula presented.)) is likely to be followed by a skewed distribution, such as an exponential distribution. This paper proposes ... -
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 ... -
