Location - allocation problem with 2 capacity constraints

Discussion created by lieke.van.amelsfort on Jun 24, 2014
My aim is to create clusters of demand points minimizing the total distance. The facilities have 2 capacity constraints. I have been able to model the problem using location-allocation including 1 capacity constraint but cannot find a way to include the second constraint as well. Is there anyone with ideas how to solve this?

Thanks in advance for your help!
