How to obtain the time for each flowitem, from when it enters the first queue until it exits through the sink, in order to calculate the average of these times and determine the Lead Time? Please, this is very important. I’ve attached the model here. Thank you!
Note: the model includes a warm-up time.
The "Composite Staytime" chart template measures the time spend between an entrance and an exit object (which would be the first queue and sink in your case).
As a bar chart it will show you the average value of all items. And you can also add it as a histogram to see the distribution of staytimes.
Thank you, sir. However, I had already tried exploring this option, but the problem is that it considers the times of the flowitems that are still in the process at the end of the simulation. For example, if there are 100 flowitems in queues or processors at the end of the process, their times will be included in the statistics, whereas it should only consider the times of those that have exited through the sink.
I just double checked and the charts definitely only show data for items that have reached the "exit object". What makes you think that it considers WIP items as well?
Hello, Mario!
I think you may use the Statistics to collect this information, I made an example at your model above. At Statistics Collector I checked each flowitem arriving and leaving the system and then, calculeted the leadtime for each one.
In addiction, you can calculate the leadtime average using the Calculted table, the unit used it's in minutes.
However, when you are using the WarmUp time, the time before the warmup time can't be considered. Just check it.
You can see more about it in this link: The Statistics Collector
I hope that help you!
Hi, Adna.
I just used the composite staytime, and comparing the results with the data I have, the average leadtime shown is apparently correct.
However, I am extremely interested in seeing the settings you made in the statistics collector. Unfortunately, the model you sent cannot be opened, as I am using version 24.1.1 and cannot update it due to the license. So, if you could somehow share the settings made in the statistics collector, I would be very grateful.
Thank you.
