Network problem validation

Recommended Posts

Hello,

 

I am working on evacuation network design problem. My network has several evacuation areas (source nodes), road segment, and shelters (destination nodes). I consider congestion as people might stick in the traffic and they have to reduce their speed in the road. My goal is to send people from hazard areas to safe areas in the defined time horizon.  So my first question is that, can I use SIMIO for simulating my model? Since my model has limited time for evacuation (Terminating problem), can I validate my problem with replications, if yes, how many replications I need? 2) Is there any other method to validate my model?

 

Thanks,

Yes, you can certainly model this in Simio, and can easily make it terminating.

I would suggest reviewing any simulation textbook for verification and validation techniques.

The general answer for number of replications is to run for a few (5-10?) replications and look at the half-width on your key output measures. If the HW is too wide, then run additional replications until all your key measures are at the precision you need.
