My favorite feature about this simulator software is that it provides me with an accurate view to what will happen in my plant if I make some changes or adjustments at any given time (e.g., process scheduling).
The user interface can be quite confusing sometimes because there are many buttons/options one needs to learn how and when they work before using them effectively. Also having multiple screens for different types of sims could use improvement as well since we have so far used all screen space just once! It's easy enough to set up your initial conditions but not too intuitive after doing it several times without reading documentation again & understanding each step needed everytime you start over from scratch. This tool has helped us optimize our operations by giving early warnings regarding bottlenecks which would otherwise go unnoticed until long after implementation had been made into practice.
