SPC Control Chart Tools for Java

Version 2.2

Add variable control charts (X-Bar R, X-Bar Sigma, Individual Range, Median Range, EWMA, MA, MAMR, MAMS and CuSum charts), attribute control charts (p-, np-, c-,  u-, and DPMO charts),  frequency histograms, and Pareto charts to Java based applications and applets using the SPC Control Chart Tools for Java.

 

X-Bar R Chart with integrated table support, frequency histograms, scroll bar and customize plot objects

The QCSPCChart SPC Control Chart Tools for Java software is an object oriented, Java based toolkit aimed at developers who want to add static and dynamic quality control charts to their Java applications. Typical users are SPC engineers and other quality control professionals creating .Java- based applications that will be used to monitor critical quality factors in manufacturing, process, and service industries. The feature rich toolkit includes templates for the most common SPC control chart types: variable control charts (X-Bar R, X-Bar Sigma, Individual Range, Median Range, EWMA, MA, MAMR, MAMS and CuSum charts), attribute control charts (p-, np-, c-,  u-, and DPMO-charts), frequency histograms, probability charts and Pareto diagrams. The software will automatically calculate SPC control limits using historical data for the supported variable control chart and attribute control chart types. Alarms can be generated for standard +3 sigma control limits, or standard SPC rule sets (WECO, Nelson, Juran, Hughes, Gitlow, AAIG, Westgard and Duncan). Alarms can be color highlighted in the SPC charts and table.  It will also calculate process capability ratios (Cp, Cpl, Cpu, Cpk and Cpm) and process performance indices (Pp, Ppl, Ppu and Ppk). Users are able to interact with charts: adding annotations, defining custom tool-tips and editing notes. There is no comparable product for Java available at any price.

bulletWestern Electric (WECO), Nelson, Juran, Hughes, Gitlow, AAIG, Westgard and Duncan Rules The software will automatically calculate and process the alarm limits for the Western Electric Runtime Rules (WE 1, 2, 3 and 4), and Supplemental (Trending) rules (WE 5, 6, 7, and 8). It will also process  Nelson, Juran, Hughes, Gitlow, AAIG, Westgard and Duncan rule sets. Rule parameters (N of M  exceed +-2 sigma for example) for any of the standard rule sets can be customized. Mix and match rules from different rule sets to create you own custom rule set. You can also define custom rules using our standardized rule templates. Details about the rules sets can be found here.

bulletControl Limit Alarm Events - Alarm events can be triggered whenever a process variable exceeds an SPC control limit.
bullet

New Alarm Features -  There is a new status line in the table section that gives a direct indication of whether or not the corresponding process variable is in, or out of, alarm. The status line has a tooltip, so if you click on an alarm, a pop-up box will show you details. Optionally, the entire column associated with a sample interval can be color highlighted to indicate an alarm condition. Alarm details can be automatically logged to the notes log. The symbol used to plot a process variable point in the primary and secondary charts can be made to change color in the event of an alarm.

bulletData logging - SPC data values can be logged to disk in the CSV (comma separated value) format, for import into spreadsheets and other programs.
bulletPrinting and Image Rendering The SPC Charts, including the integrated tables, can be output to any Windows supported printer and Java JPG file.

Custom Programming Services

bullet SPC Control Chart Tools for Java is an extremely powerful and flexible software package. It contains over 1000  methods and properties in more than 120 classes. The user manual and  help file documentation are more than 1500 pages. This can be overwhelming to the average programmer who wants to start programming today and have the prototype of an application working in a week.
bulletThe variety of user interfaces for charting applications is as diverse as the industries using the software. The end-user of an application at a drug company expects to interact with the chart in a manner different than that of an end-user in the automotive industry.
bulletWe know that your application may be similar to, but still uniquely different from any of our example programs. To that end we offer our programming services to write for you a custom example program that demonstrates how to code the chart format and user interface you want. That jump start to your project can save you many weeks of work and make you look like a chart programming genius. All  you have to be able to do is describe in detail what you want the example to do.
bulletUsing SPC Control Chart Tools for Java , our range of expertise includes Applet, J2EE and SQL programming languages. For more information or a quote, please contact our sales department at sales@quinn-curtis.com
