Hi. I´d like to know if there´s a way to keep a certain distance between chosen facilities in location allocation. I use a cutoff of 1500 m. But still some chosen facilities have a distance of just a few meters to each other.
In your use case (screen shot) the chosen sites are the correct solution. You could choose candidates that further away from each other, or at least the distance you care about. That way the chosen sites will not be near by. You can use the Create Random Points tool and specify the Minimum Allowed Distance that works for you to create candidates with the minimum spacing.
