SPC Wizard is a
state-of-the-art data mining program for SPC analysis, unique in
that it combines a complete SPC training module containing
process simulations with full functionality for real-time data entry and
analysis.
Analyses include F-test, t-test, multi-vari and any combination of
displayed factors dependant and independent variables.
SPC Wizard is a Windows program and currently available in
English, German, Dutch and Spanish.
Training SPC for variables
The training module of SPC Wizard for variables contains a
graphical simulation of a launcher firing tennis balls. The program
records the positions where the balls land. Landing position is
influenced by both common and special causes of variation. The program
is developed for students who already have a basic knowledge of SPC. It
teaches them how to apply SPC to production processes. Special causes of
variation can be programmed to occur at pre-set shot numbers so
customized examples of data can be produced for training. Students can
make control charts and calculate control limits to detect the special
causes of variation. The program supports the students with full
explanation of the principles and many helpful features. The program
also describes capability analysis and the usage of the capability
indices (Cp, Cpk, Pp and Ppk).
Process Improvement Game
In the game mode the student is confronted with 4 possible special
causes of variation: Two different suppliers of balls, the room
temperature, inconsistency of the launcher caused by a weak spring and
debris on the floor. The student has to use the control chart to
identify which of the special causes are affecting the process. The game
is won when the landing position of the last 100 shots has an acceptable
Ppk value. The game is lost if the student tries to remove a special
cause which was not affecting the process.
Training SPC for attributes
In the training module, attribute processes are simulated by taking
samples from a box filled with colored beads. The results of the
simulation can be quickly displayed on control charts, a Pareto chart, a
scattergram or a table of results. The training module also contains a
complete simulation of Deming's red beads experiment.
Real-time analysis for variables and attributes
SPC Wizard is capable of reading data from Access®, Excel® or
DataLyzer® directly. This means you can directly show control charts and
capability analysis with superb analysis possibilities of your data
without manipulation of your data files. With a set-up Wizard, you can
quickly define a data entry table for new data, including date and time
fields, note fields, fields with other production information (like
process settings and tracking and tracing information). Once data has
been entered you have full analysis capabilities with the control chart,
histogram, Pareto chart and scattergram.

-
Add information to the samples to allow
correlation analysis between process settings and attribute defects.
-
Make correlations between different tables from
any SPC Wizard, Access® or Excel® file based on a common parameter (eg.
workorder nr.) or based on time differences.
