How to create an elevator system for people with networknode ?

[ FlexSim 22.2.0 ]

How can I model the system Case 2 (network node + elevator) with the same behavior than the case 3 (A* + PeopleElevator) ?

Or is there a better way ?

Elevators.fsm

Why ? I often have problems with Astar and people elevators (strange behaviours, no feedback on errors, no mistakes detection (and I do a lot ;)), not confident of all the ways a respected). I would like to keep the control on the navigation system. And I prefer drawing the path than all the possibles barriers of the buildings that I model.

We build a proof of concept model for this a while ago. It uses a Process Flow that is more or less modeled after the AGV elevator Process Flow. It creates a preempting task sequence for the task executer when it needs to use the elevator.

We even have a video showcasing the model (In German with English subtitles available).

As I said, the model is mostly a proof of concept. But it might serve as a starting point to integrate more complex features (multiple travellers per trip, request prioritization, etc.)

Hi, Thank you very much for your answer. Indeed your model is a very good base, as you say yourself.

In my case, if I want to be able to integrate compagnons, different types of transport and the elevator logic itself, I have to take a lot of time to develop it (I'm not developing 😉 and I think the algorithm elevators is complex when you add different elevators.).

1) So for the moment, Flexsim does not have an "elevator object" perfectly compatible with the network node.

2) It's always about mixing NN and Astar.

Thanks for sharing your knowledge
