AGV Deadlock

[Huo]

[ FlexSim 22.2.0 ]

Hello All,

Operational Description:
A1-A4 are the infeed sections.
B1-B4 are the outfeed sections.
There are four AGVs that start working from the charging area.

Problem:
Deadlock occurs during operation.

My idea: Can the AGVs be redirected to the nearest bypass point to avoid deadlock?
For example, AGV4 will come to brCP1 to resolve the deadlock issue.

Is this a common solution?

Or are there any other solutions?

Kind regards

Hey @Huo, you could take a look at the documentation section on preventing collisions and deadlock. Some of the suggestions include using control areas [another resource] for two-way paths that may cause dead-locks. In newer versions of FlexSim (v.23+) the OnAllocationFailed trigger will tell you if deadlock occurred.
