The JQT Editorial Review Board instituted the Lloyd S. Nelson Award recognizing the article in the most recent volume, beginning with Volume 35 (2003), having the "greatest immediate impact to practitioners." The Statistics Division of ASQ, headed by Chair Davis Balestracci, carefully studied the articles appearing in last year’s issues. We greatly appreciate the dedication and effort of Davis ...

Where you can find the statistical quality control strategies and tools for continual improvement easily? Is it in the book store? On-line book store? are you sure? Keep in mind that you will find the book in this site. This book is very referred for you because it gives not only the experience but also lesson. The lessons are very valuable to serve for you, that's not about who are reading thi...

Although it is important to test quality of coal used in thermal power station, it is more important to know how to interpret the data from the results. No single test can be used independently to determine the quality of coal. Machine interference is a significant problem in many manufacturing system and testing equipments. The variation of results for testing equipments may be due to various ...

Existing quality controlmethods for railway ballast are arduous and expensive since they are based onmanual material inspections. Thus, test intervals are typically fairly wide. As a consequence, short-term andmid-term fluctuations of ballast quality may not be detected. This results in increased costs for maintenance work such as tamping. To make test intervals shorter and even allow for conti...

In the study of network intrusion, much attention has been drawn to on-time detection of intrusion to safeguard public and private interest and to capture the law-breakers. Even though various methods have been found in literature, some situations warrant us to determine intrusions of network in real-time to prevent further undue harm to the computer network as and when they occur. This approac...

Originally developed at Bell Laboratories by Dr Walter Shewhart [1] in 1924 specifically to help detect statistical changes in process quality, control charts have since become one of several primary tools of quality control and process improvement. Quality control charts are chronological graphs of process data that, although based in statistical theory, are easy for practitioners to use and i...

An important component of quality control for statistical graphics software is the ability not only to test that code runs without errors, but also to test that code produces the right result. The simple way to test for the correct result in graphical output is to test whether a test file differs from a control file; this is effective in determining whether a difference exists. However, the tes...

An advisory decision support system has been presented in this paper. This system helps in collecting statistical data and thereafter analyzes the enormous volume of data and aids in making quality related decisions. In contrary to conventional SPC applications where the analyzed results have to be interpreted by quality control specialists, MES based unmanned manufacturing environments require...

The statistical quality control process on raw materials and/or the final product of traditional Chinese medicine (TCM) is examined. We develop a statistical quality control (QC) method to assess a proposed consistency index of raw materials from different sources and/or final products manufactured at different sites. The idea is to construct a 95% confidence interval for a proposed consistency...
