Simulator Software



Training tool used to simulate manufacturing processes and generate data for Design of Experiments (DOE) and Robust Tolerance Analysis courses.



Version 2.2 for Windows  7, 10 and 11, including 64-bit versions.

Download Full Version of Software Above – Try it Free for 30 Days

A full version of the software can be downloaded above and used for free for a 30-day trial.  After 30 days, if you want to continue using the software, you must purchase a license.  The file sim22.exe will be downloaded.  Executing this file will install the software on your system including the instructor’s guide.

Purchasing Software

To continue using the software after the 30-day trial period, you must purchase a license for the software.  A user name and license code will be emailed to you along with further instructions.   You also get free upgrades for 1 year.  Site licenses are also available.

Simulator performs simulations of products and process for use in training including the courses Screening Experiments, Response Surface Studies, and Robust Tolerance Analysis.  One simulation is for the Heat Sealer case study in the book Optimization & Variation Reduction in Quality.  Tutorials are also provided for the Heat Sealer and Pump simulations in the VarTran user manual.  Besides the 5 simulations provided, you can add your own simulations.

Upon starting the program, a list of available simulations is displayed.  Selecting a simulation displays a control panel for adjusting the process settings or product characteristics.  Data can be collected on the resulting performance s including performing a capability study.  Data can also be generated for designed experiments created using other packages.  The effects of adjusting the inputs can be studied.  One can also tighten tolerances on the inputs.

The goal is to adjust the input settings to optimize the performance of the product/process.  Further improvements can be made by selectively tightening tolerances if needed.  The goal is to minimize the number and amount of tolerances tightened.  This allows the principles of robust design and tolerance analysis to be demonstrated in a hands-on fashion.
