Hello again Mr. Sandhu: Using your feedback, I investigated the Facilities table. I understand the column "Capacity" refers to the total available supply for each facility and "Demand Count" refers to the number of demand points that receive some (or all) of their need from the facilities. However, which column represents the "demand assigned to them"? I see two other columns that are helpful --> "Demand Weight" which in my case, is equal to "Demand Count" since the weights are all 1. The other column is "Total_Length" that I believe represents the cost (in my case, length in miles) for a product to go from the facility to the point of demand. Also, in the ArcGIS help information for Maximum Capacitated Coverage, it states that "an allocated demand point has all or none of its demand weight assigned to a facility; that is, demand isn't apportioned with this problem type". First, what is meant by Demand Weight? Then, what does that statement above mean? Does it mean that a demand point will only get either 0% OR 100% of its demand needed? For instance, a demand point can not get 50% of its demand needed? Finally, does this tool allocate from multiple facilities to a single demand point to satisfy demand? If so, where in the table can you find (1) the facilities contributing to the demand point and (2) the amount each facility is contributing? Thank you for any assistance with these questions.

Hello -- I am new to using Network Analyst -- and currently exploring the Allocation-Location options of ArcGIS 10.1. I am trying to find the right tool to distribute a fixed supply of vegetables (pts. of supply) to consumers (pts. of demand) in terms of least cost (as distance). Using the Maximize Capacitated Coverage option, I can see the facilities that distribute to the demand points using the SHORTEST distance criteria. HOWEVER, this RESULT does not show (1) the supply utilization --> how much of the total supply (capacity) has been distributed or (2) the demand fulfilled --> how much of the demand was met (in terms of % demand met at each point). Can someone please let me know if I am using the right tool -- or if I need to use a combination of tools to solve this problem? Thank you, Jamie P.
