Entity arrival

Recommended Posts

Let's say I want exactly 100 entities arrive where the arrival of each one follows a normal distribution with mean 1 hour and standard deviation of 5 minutes from the start of the simulation. How can I model that within SIMIO? The interarrival time doesn't make sense because I don't know / care what the interrarrival time between each entity is.

I realize that I could randomly generate 100 normal random variables outside of SIMIO and input them all as an appointment, but I am wondering if there is a better way especially if I want to do many replications with a different set of 100 random variables each time.

Check my attached model.

I'm not sure if this was the best approach, but it works.

I created two events:

  • One is triggered 100 times to executes another process 100 times.
  • Each process will run its own Delay step and fire the second event to trigger the source.

Let me know if this isn't what you need.
