The results are not the same in each round.

Hello. I has wondering about model result. (INPUT-OUT)

Run round 1

Run round 2

Run round 3

Run round 4

Run round 5

Even thourgh I don't check out Repeat random streams in Statistic menu and run time is 1 hour in each round.

Why the model result are not the same. Thank You.

Have you looked at the guidances on repeatability? https://docs.flexsim.com/en/23.0/BestPractices/ModelRepeatability/ModelRepeatability.html

I has looked and checked from some guidances topic, but the problem are not complete and I still don't understand all topic. Then I try to run the model over stop time for find some error message.

It show message LINK PARITY ERROR(cleanup)in System Console.

But in Compiler Console not have any message. It in System Console only.

Ah yes - I'm afraid to say this is bad news - you'll need to try and find the cause of that error first. Load the model afresh and run until it happens again. Reset and run and see if it happens at the same time. If so - home in on the exact event and see if you can tell why it's happening.

If you're using conveyors, make sure you're not removing a flowitem that has an traversal event scheduled - ie. it is stopped at a decision point or station etc.

If you can't find the cause then post your model telling us what you've tried up to then and your best guess at where/when it happens and we'll take a look.

Before I tried to find the cause of that error. I not found it.

In the model I has define model run time at 1 hour, the error will not notift between 1 hour runing and uncertain time to be error in each round of model run. Generally this error has come since 1 hour after model stop by stop time
(Model run time are 11 AM - 12 AM and this erro has come since 1 PM)

I has attached model here. Central Optimal Spare Old.fs

First thing to say is that there's a pointer node in your model called Queue that is just a pointer node - I'd remove it.

After several runs exporting the event log to compare events and seeing differences (as yet the reason is unknown to me) I've now seen an example of the link parity error which you can see here happened at 2617.267 seconds.

Since the model is not yet repeatable this doesn't help is yet but you can see there's an issue somewhere and in this case it occurs before the hour's run is complete.

It's probably also worth pointing out that you model appears to have 140x more activities than it needs since you seem to have modelled everything (copied and configured) instead of using object process flows. This might also use more memory than it would using object process flows.

I agree. From you tell about I have 140x activites it need. I still don't understand enough abount object proces flow. So I will try to lerning to use object process flow and other for future. Thank You So Much.
