How to get Time in System statistic (all replications) by PFM?

Hi, I am just trying to obtain in one report all replication values of the statistic "Time In System" of flowitems by using experimenter (performance measures, PFM). I figured out that PFM are only related with objects but not flowitems. I also tried with the composite time in dashboard and I can see the average of each replication but it does not report all of them in a whole report. I also tried to export dashboard statistics to Excel but it does not work out. Any help? thks !!!!

What are you using to create that "Time in System" statistic?

Hi Joshua, Time in System is already a tracked variable, but based on my experience in other simulation software, that statistic is coming by default in entities sumaries or reports generated. However, in Flexsim, it has not been easy to me to find out its replications values.

First, you need to make a Performance Measure that records the value of the TrackedVariable:

TrackedVariable("TimeInSystem").average

I left the name of the Performance Measure "PFM1".

Then, run an experiment. After that, you can add a Calculated Table that has the following query:

SELECT Scenario, AVG(PFM1) AS AvgPFM1
FROM Experiment.PerformanceMeasures
GROUP BY Scenario

In the attached model, I did so, and added a chart that points at that table.

timeinsystembyscenario.fsm

The query above averages the value per scenario. To see all Performance Measures for all replications, you can use this query:

SELECT *
FROM Experiment.PerformanceMeasures

Hi, Jordan ....thanks for your previous help. ¿Can you help me now when I need to get the time in system by each item type?
