Thank you for ur time.
My problem has an around 80,000 supply (sources, can supply tons of material) points and 200 possible plant locations (facilities). Each supply point can supply a fixed amount of material (tons of materials) to the possible facilities (plants). I want to find the best 10 possible locations of plants to minimize the total transportation cost. Here transportation cost will be distance x tons of materials supplied to the plant.

I believe the facility location model select the possible location towards the sources having large number of tons of supply materials.

Does the location-allocation module in ArcGIS 10.1 model this problem?
How to input the individual capacity of the sources into the location-allocation module in arcgis10.1.

Your insightful thought is appreciated.
