A mixed HWMA‐CUSUM mean chart with an application to manufacturing process
Quality and Reliability Engineering International, 2020AbstractMemory‐type control charts play a significant role to identify slight changes in the parameters of the production process. In this article, we have proposed a new cumulative sum chart that utilizes the statistic of the homogeneously weighted moving average chart.

Quality and Reliability Engineering International, 2021
AbstractControl charts are designed under the normality assumption of the quality characteristic of the process. However, the normality assumption rarely holds in practice. In non‐normal conditions, parametric charts tend to display more false alarm rates and invalid out‐of‐control comparisons.

On Designing Mixed Nonparametric Control Chart for Monitoring the Manufacturing Processes
Arabian Journal for Science and Engineering, 2021Efficient control charts are used to maintain and improve the manufacturing, industrial and service processes. Control chart is a basic tool of quality practitioners for producing products that meet market requirements in terms of quality, reliability and functionality. Lack of normality is a common occurrence in these processes.

Recognition and quality assessment of data charts in mixed-mode documents
International Journal of Document Analysis and Recognition (IJDAR), 2008Data charts can be used to effectively compress large amounts of complex information and can convey information in an efficient and succinct manner. It is now easier to create data charts by using a variety of automated software systems. These data charts are routinely inserted in text documents and are widely disseminated over many different media ...

Gradation Chart for Asphalt Mixes: Development
Journal of Materials in Civil Engineering, 2007The gradation chart approach is based on the two parameters of Fuller's model (i.e., maximum size diameter and shape factor) which are obtained by fitting well-graded structures like those of Superpave or Covenin. ASTM mathematical definitions for gravel and sand, and Fuller's model are used to develop an analytical expression for a gravel-to-sand ...

On a class of mixed EWMA‐CUSUM median control charts for process monitoring
Quality and Reliability Engineering International, 2020AbstractMonitoring of any manufacturing, production, or industrial process can be controlled and improved by removing these special cause of variations using control charts. Shewhart‐type control charts are effective to control a large amount of special variations, whereas, cumulative sum (CUSUM) and exponentially weighted moving average (EWMA) charts ...

A multivariate sign chart for monitoring dependence among mixed-type data
Computers & Industrial Engineering, 2018Abstract Statistical process control (SPC) has been widely utilised for quality improvement and surveillance in industrial engineering. Modern industrial applications have witnessed more and more mixed-type quality characteristics such as those consisting of ordinal categorical and continuous ones.
