For us to understand the errors, it would be helpful for you to upload your model if possible. This would allow us to see why this error is happening.

I am sorry. Due to my company's policy. I cannot upload files. My model is using two taskexecuters to carry goods between source and sink in a "straight road". In order to prevent deadlock, I put many control points on the road and use some global variables to monitor the taskexecuters. Redirect them to parting zone once found deadlock. The phenomenon is: after running several simulation hours, there is "FlexScript exception" such as "Array index out of bounds at MODEL:/AGVNetwork>variables/" . It is found that one taskexecuter stop out of control point and become "no respond" anymore. Can you give me some hints to solve that?

We are unable to understand the detail of your error if there is no model here. Either you can make a simplified version of your model which it can duplicate your error, or you can submit as Private so that the support team can look into it.

Are you using Express version or full version?

@david.chan

My limitation is my company's network, which blocks all file upload. So sad..! I am using full version 2018.1.1 (1 month trial). I found the issue is due to I used the command "agv.redirect(CPX, REDIRECT_AND_CONTINUE_ON_ARRIVAL)" frequently. When it is applied on the taskexecuter being in the status "On Resource Available -> Travel to Home Location", sometime it will cause the te "dead", which without respond, cannot read "currentCP". And it will stop and block another te.

But I have to use the command to prevent deadlock. Any suggestion or sample in preventing deadlock using two taskexecuter in a straight road?

@Pui Fong C

1. Did you use De-allocated Type as Deallocate when pass current for CP?

2. You can also set the maximum allocation to more than 1.

Yes I did.

My model need to show two taskexecuters running without collision. So I cannot use this option.

You can try to select accumulation type to "default accumulation" which can help you avoid collision with more than 1 maximum allocation.
