Location Allocation in ArcGIS 10

GarethYoung — Fri, 10 Dec 2010 13:40:20 GMT

Hi,

I'm trying to use the location allocation component of Network Analyst to solve a problem. I want to find the minimum number of facilities that can be used to supply a specific demand. However, there is a maximum demand for each facility but I can't find the relevant place to enter this in the dialogs.

Any advice will be greatly appreciated.

Thanks

Gareth

Gareth,
If I understand correctly, you want to add capacity on your facilities. That is not supported in Location-Allocation. It solves the minimum number of facilities such that demand is assigned to the closest chosen facility.
Can you describe what type of problem you are trying to solve with capacity. Perhaps their are other ways to achive your goals.
Regards,

Hi Jay,

I'm trying to find the minimum number of schools that can service and area with a specific demand which is based on postcode data. However, the maximum number of students that any school can cater for is 1,000 so I need to be able to set a maximum level for each facility within the model.
