How to get the collecting time of a process flow Sink from its tree ?

Hi,

I asked this question before for getting the processing time of a Process Flow instance of a FixedResource from its tree.

https://answers.flexsim.com/questions/63315/how-to-get-process-time-of-an-instance-from-its-tr.html

I got a very good answer from @phil.bobo and now i am trying to do the same for getting the collecting time of a custom Process Flow Sink. For that I just modified a FixedResource to make it destroy all objects getting in and set its state to "collecting".

I tried using the same method

current.stats.state().getTotalTimeAt("collecting")

but it returns 0 although the collecting time in the tree has a positive value. The tree looks like this on reset:

How should I proceed for getting the collecting time of a custom Sink via FlexScript ?

Best regards,

Software Version:

FlexSim 20.0.1

That should work fine. You would need to post an example model demonstrating the problem for us to be able to figure out why that isn't working.

Here is a test model that replicates the issue.

Actually when I stop the model, the collecting time is updated, but when I continue running the model it sill displays 0. So the proposed solution is unfortunately not helping me.

I'm not sure why passing the category as a string isn't giving you back the result you are looking for, but you can work around it by passing the state number:

current.stats.state().getTotalTimeAt(STATE_COLLECTING)

I'll add a case to the dev list to look into it.

@Sebastian Using FlexSim 2020 using the getTotalTimeAt() seems to be working fine. It calculates the current time at that state, even though the value in the tree may show 0. The tree value only updates when the object changes states or when the model stops.

If your'e trying to get the total time between the first flowitem that enters the Sink and some other flowitem entering, you can add a Wait for Event activity and listen to the Sink's OnEntry trigger to record that information.

I hope this helps!

@Matt Long. Thank you for the answer !

I did not notice the collecting time was not updating until the state changes. I will find a solution knowing that.

When you use getTotalTimeAt(), it should account for the current state without having to explicitly change the state.

It seems to be working fine to me:
