Thank you Jay for your comment. However, i don't think that will work since I have 12250 demand points and 10.000 possible facility locations. If I have to delete the demand points by hand it will take me ages. To be more clear about the problem: I have 12250 demand points (Households) and I have 10.000 possible container locations in a specific area. I want to locate the least amount of containers and I use three different types of containers: capacity_1 = 70 demand points, capacity_2 = 55 demand points, and capacity_3 = 45. Container_1 can only be located near water, c2 only near main roads, and c3 can be located everywhere. I already generated these points for each container and solved this problem sequentially; first c1 than c2, c3. Do you have any tips to solve this problem simultaneously? Or do I really have to do this by hand? Best, Hank

I would like to define the container location in a specific area for three different types of containers all with a specific capacity. Is it possible to solve this problem simultaneously with a 'maximize capacitated coverage solver'. It is possible to do this sequentially, but that won't give the best output. So the question is: Is it possible to assign a specific capacity to a specific possible facility point?

I try to understand how the maximize capacitated coverage exactly works. I've already done many iterations for my facility location problem and during the analysis of the output i don't understand why some decisions are taken by the solver. For example; if i select 238 facilities i serve 9360 demand points. If i select 239 facilities i serve 9331 demand points, which is less demand points with more facilities while opposite was expected. Could someone provide me the integer programming model/math behind this solver? It would be much appreciated. Thank you! My unfinished model description is attached.

Thank you Jay for your comment. That is actually what i did. It felt like there should be a better way than these iterations.

Hi all, Currently, i'm researching the possible container locations in a specific area for a large set of demand points. These containers have all the same capacity. By using 'maximize capacitated coverage' i'm aiming for a high efficiency for each container and i'm able to set a certain capacity. However, i actually want to find the least amount of containers to serve the whole area. Therefore, i would preferably use 'maximize attendance and minimize facilities'. Unfortunately it is not possible to add a capacity to this solver. Or is there a way to do so? Could someone help me with this problem?
