How to choose a queue？

Hello, my friends. Now I want to implement a logic. In the model, the AGV prefers to move the goods to the group Q, but when the group Q is full, the AGV moves the goods to groupQ1. when there is an empty position in the group Q, the AGV moves the goods to the groupQ1 again.

Thanks for your help!

Hey @Kongxincaier, in the model you've provided, the queues in Group Q never get full. Your logic makes it so the AGV picks up a box then decides whether or not to put it in a random Queue. If that queue is full, then it simply picks up another box and never places that new box anywhere. You'll need to instead pick a different location to move the box to in the group to even get Group Q to fill up.

If you want to see if there's room in the Group, you can setup a function to check all the space in the Group Q. For example:

/**Custom Code*/
Group q = Group("Q");
for (int i = 1; i <= q.length; i++) {
  Object curQ = q[i];
  int maxContent = curQ.getProperty("MaxContent");
  int curContent = curQ.subnodes.length;
  if (curContent < maxContent) {
    return 1;
  }
}
return 0;

This will return 1 if there's still room in the Group Q; otherwise, return 0. So, you can have a decide activity check to see if there's more room in the Group, and if there isn't, then have it deliver to the Q1 group.
