Hi there,

I am working on a project that needs to find out the three closet supermarkets belonging to different companies around each census block centroid. I am using the Network Analyst ??? Closet Facility Tool, using census block centroids as incidents, supermarkets as facilities and setting up the number of facility as three. The problem is, however, for any three nearest facilities to be found, I want them to belong to different companies. I have no idea how to define constrains on facility types (different companies) during this analysis. Could anyone have any idea? Many thanks in advance.
