I'm teaching an Operations Management Class. A long time ago, there was a simple DOS-based product called MPX. It was based on queuing theory and let you model manufacturing processes. There was nice case that went with it call GTHUBS-- something like 5-10 SKU's going through 5-10 machines, with some different routings, set-ups, labor requirements, etc.. It was interesting to try different things to see what impact the changes had on overall cycle time.

The DOS interface was ugly, but super simple. And, students could figure it out.

I can no longer find this program or case study.

Does anyone still use this? Does anyone have a good replacement for this that they use in their classes?


  • $\begingroup$ I don't know about MPX, but with using modern simulations software, you could try this with many options and features. Some of them have the 2D/3D area to represent the graphical view of the model. $\endgroup$
