sensitivity analysis

[NinaK]

Hello,

How to make a sensitivity analysis in ARENA? are there any in-built functions?

regards,
Nina

Again, this response is overdue!

Sensitivity analysis in Arena, is typically performed using the OptQuest software that comes with it. However, if you dont have access to the same, the simple other way would be to manually change data and run.
If you want to run many scenarios, you mimght want to setup an excel file interface with all the various scenarios and then make arena read in a different cell of input parameters after each set of replications (i think using VBA script is the way to do this) . This will enable to you automate experimentation.

Additionally, I'll mention that Arena comes with a Process ANalyzer ("PAN"). This feature is described in Simulation with Arena, 4th edition, by W. David Kelton, Randall P. Sadowski, and David T. Sturrock, pages 277-282. PAN has a less intuitive interface than I might wish, but does provide a convenient way of running multiple scenarios (e.g., 2 or 3 machines X 1, 2, or 3 repair people -- that's six scenarios) each run for multiple replications.
