Process simulation and modeling software
Reviews and comparisons of the software used to map, model and simulate processes. Every product is scored against the same published rubric, and every claim carries a source and the date it was checked.
Each bar is the rubric in one line: a segment per criterion, drawn at the width of its weight and filled to its score. 1. Modeling capability (20), 2. Ease of learning (20), 3. Results and experimentation (20), 4. Pricing and total cost (15), 5. Visualization and communication (10), 6. Platform and deployment (10), 7. Learning resources and support (5).

We are choosing between Arena and FlexSim. Which is better?
Two mature discrete event tools, both Windows only, neither publishing a price. The question that separates them is not capability. It is what has to exist at the end of the project.
Everyone here already knows Arena. Is there a reason to shortlist anything else?
Arena is taught in more universities than anything else here, and publishes no price for any edition. What a buyer gains by leaving it, and what they lose.
Do I need to buy simulation software, or will a free process modeling tool answer my question?
One is the easiest simulation tool in its category and costs several thousand a seat. The other simulates resources and shifts for nothing. Which one your process needs.
Most simulation vendors publish a free edition that never expires. The caps are the wrong thing to compare. What separates them is whether the license permits the work you were planning to do.
One of the oldest names in process simulation was acquired in 2022 and its own domain now redirects to its owner. We could not score it against our rubric, and the reason is the review.
Simulation software is a Windows category with two exceptions. What the publishers' own system requirements say, and what a browser version is and is not.
3D sells the software and then sits unused. Why the buyers who paid for it most often skip it, and what actually persuades a room.
