The Bean Machine
The Bean Machine for Windows
The Bean Machine for Windows is a software
package used to teach, demonstrate, and understand variation. Important
concepts and tools of Statistical Process Control (SPC) can be demonstrated
and evaluated. The Bean Machine simulates the performance of a Quincunx
in which beans are dropped from a funnel through rows of staggered
pins. Each bean has a 50:50 chance of falling to the left or right
when it hits a pin. Movements of the funnel represent Special Causes
of Variation while the rows of pins represent Common Causes.
Features
- Results of the falling beans can be displayed in either a histogram or run chart fashion.
- The Bean Machine can run at different speeds and in an open or hidden mode to demonstrate various concepts.
- Individual results, averages, and/or ranges can be displayed.
- Measurement variation can be explained by grouping the rows of pins.
- Specifications, action limits, etc., can be displayed and used to evaluate effectiveness.
- Process adjustment strategies can be manually or automatically evaluated.
- Dr. Deming's four "FUNNEL RULES" can be illustrated.
- Can be used as a bead box, chip box, or simulator.
System Requirements: Program can be run on a PC with Windows operating system.
