How can I move patients to nearest exit?

Hi!

I want to move patients to nearest exit for each patient.

I think I can solve this problem if I can choose 'walk destination to group location.' But I can't find the way. Or is there a way to solve it using 'decide based distance'?

Please let me know some ways.

Important thing is patients have to move simultaneously.

Thank you.

If you have the exits as members of a location group, each patient can acquire one while sorting by distance in ascending order.

Directly after acquiring an exit, you copy the value to a different label to preserve it and release the location again, so other patients can acquire it. To make sure that each patient can choose between all available exits, you can place a zone with a max. content of 1 around the activities. The label the location was copied to can then be used in a Walk activity.

Thank you so much!!

Is there any other way to use 'decide'?

I think the 'decide item' will have the function to send tokens to the walk process where an exit close to the token is set as the destination.

Can you let me know some ways?

WIth only two exits you could use a Decide activity set to "Conditional Decide" to send the token to one of two Walk activities, depending on which object is closer.

In a more general case where you have to compare the distance to more than two items, the Decide activity probably wouldn't be useful.

You would either find the closest exit by acquiring/pulling it with a query like in my original answer or find the closest object with custom code.

Wow, ok. It seems that it's better to use your original answer to my model.

Thank you!
