Default How to track "Waiting for operator" time ?

I need to collect "waiting for operator" time for an entire simulation run. What is the best way to do so.
Also if I have to calculate a custom value from the model how can I do so. For example currently I calculate "Waiting to be seen by a doctor" (WTBS) time by a time stamp system and storing that value in a global table. Then after I run the model I copy these values to excel and then find the steady state and average WTBS times. I wonder if I can form these graphs in flexsim itself which will make it better for presenting.

Did you have a look how the Dashboard is working? There you can define Tracked Variables. As I understood you, you are exactly looking for this.
If you also are looking for a steady state, just calculate it as often as it is changing.
Maybe you share an example model with us an we can give you the right direction with this.
For your "waiting for doctor" question, there would be different ways to solve it. I would set a timestamp with the information, when the customer started waiting. Get it and calculate waiting time when tasksequence for operator recieves.

Thanks for the reply. I got the dashboard part. Was pretty straight forward I guess.
Please find the model attached.
If you go to user commands > onprocessfinish.. U ll find that after procnum == 2 and loop == 0 I record a time in the table called WTBS. This is the time from arrival till the end of this process. I want to track average WTBS time of the model at any given point of time vs the total length of stay (That I calculate at discharge) as a pie chart.
I also use this as a measure to calculate steady state. So could you please explain how I can plot the steady state in the dashboard.

I think you only have to add a new Tracked Variable. Let´s say "RecordedState" to it and make it time weighted.
Then add the line:

settrackedvariable("RecordedState",time - getlabelnum(patient,"Arrival time"));

in your Usercommand. Now you only have to add another Chart and use the Tracked Variable as shown variable in it!

I did this in attached model. But am not sure, if this is completely what you are looking for and with my explanations you also can solve it on your own.
