About the update of AGV in Version 23.0

I didn't use the script about AGV before, so i don't know how to use the scripts below:


  • Added user-customizable deadlock recovery. Added parameters to the OnAllocationFailed trigger that lets the user know if the allocation request represents a deadlock, as well as an array that is the deadlock cycle. The user can thus implement logic if the allocation failure is a deadlock, and return 1 to tell the system that the deadlock has been handled.
  • New features for AMR simulation:
    • Added an OnNavigationFailed trigger that is fired when the AGV can't resolve a valid path to a destination. This is to give the user the ability to handle the error. Returning 1 means try again, returning 2 means end the task.
    • Added parameters to the Custom Path Cost: a forward/backward boolean and a reference to the AGV if there is one.
  • Added AGV.traversalPoints property and AGV.TraversalPoint class.
  • Made AGV.AllocationPoint.stopDist writable.
  • Added AGV.stopRecharge() and AGV.addAllocationPoint() methods.

Hi @Davidchann ,

Maybe you can also take a look at:
Kiva System Demo Model - FlexSim Community

In this model all the new features are used.

@Davidchann, then it is up to you to acquire this knowledge. You can contact a FlexSim distributor and ask for a course about self defined content. Sorry, there aren’t tutorials available right away if new features are introduced.

You can start by reading through the AGV class reference page in the manual. It explains the meaning of each property and function of the methods.

https://docs.flexsim.com/en/23.1/Reference/CodingInFlexSim/FlexScriptAPIReference/AGV/AGV.html

In the bug report linked below I uploaded a test model that I build which uses the new properties to allocate additional control points or change the timing of the allocation/deallocation to account for the geometry of the vehicle. You can have a look at this as an example.
