When is AGV blocked?

Hi,

yesterday I discovered that AGV doesn't change the state when it receives a new mission, but it can't start it. I reproduced the issue in the model agv-blocked.fsm.

The task executer 3 receives a travel task which can't start because the task executer 1 has already allocated the area. Correctly the TE3 doesn't go, but its state is set to "travel_empty" instead of "blocked". Is it a bug or is there an error in my implementation?

After some test I noted that the state_blocked is set only when the AGV reaches a control point and can't allocate the next one or when it must stop to due to accumulation rule. Can someone confirm it?

FlexSim 17.1.4
agv modulestate_blocked
agv-blocked.fsm (20.4 KiB)

Hi @Jeff Nordgren,

I implemented a workaround to solve the issue, but I believe that is a bug. I don't check if it is solved in the last version (17.2.x).

This is still the same in 17.2.1. I'll added a case to the dev list.
