I'm looking to create service areas around a number of facilities each with a set population max capacity. I have centroids from census data that are snapped to the network representing 'demand.' Is there anyway I can make the Create Service Area tool in Network Analyst consider this? For example, if the capacity is 100 and the centroid's population is 80, the service area will encompass this first centroid, but cut itself off before it reaches the next. I have tried just about every combination of polygon generation, break values, etc. I can think of and cannot seem to figure it out! Thanks in advance.
