Choosing the not occupied network node

Hello,

I´m trying to achieve the network where task executors are avoiding each other (and are not conflicting on exact point in network nodes either), which is the main issue I am having at this moment.

In the model below I am able to quite well control the opening and closing net nodes how I need to to avoid conflicting in the middle of the node, but on the points there are still conflicts happening.

In my opinion it is caused by too early opening of nodes after task executor passes them, however I was not able to find workaround it.

Ideal scenario would be for executor to evaluate on each point the best possible way to final station, so he would avoid node that is already closed (red square below).

Is there any better way how to solve this issue, and let task executors freely travel on nodes without conflicting with each other?

Thank you so much!

@Zdenek K2 Your network is not very big so you can replace it with an AGV network. You only have to create a control area around your crossings and you are done with collisions. On top of that your travelling becomes much more realistic.

Hello there,

I was working with the idea of using AGV networks, however for my usage is this way of traveling more realistic.

I will also need to add more aisles (20-30), and also multiple floors above the first one, which made usage of AGVs not really convinient.

Sincerely,

Zdeněk
