What are the features of location allocation analysis?

What are the features of location allocation analysis?

The location-allocation analysis layer also appears in the table of contents as a composite layer containing six corresponding feature layers: Facilities, Demand Points, Lines, Point Barriers, Line Barriers, and Polygon Barriers. Each of the six feature layers has default symbology that can be modified in its Layer Properties dialog box.

Where to find location allocation in Network analyst?

When you create a location-allocation analysis layer, it shows up in the Network Analyst window along with its six network analysis classes —Facilities, Demand Points, Lines, Point Barriers, Line Barriers, and Polygon Barriers.

How are input and output fields used in location allocation?

Within a network analysis class, there may be a combination of input fields, output fields, and input/output fields. You enter data into input fields, which are then used by the location-allocation solver to set up the problem. In contrast, output fields store results from the solve process and give you information about the solution.

Is there limit to number of factors that can be considered in location allocation?

There is no limit to the number of factors you might consider in determining suitability for your facilities. Choosing the right factors and finding sites that meet those factors is all part of a suitability analysis, which should be performed prior to setting up a location-allocation problem.

How is location allocation a twofold problem?

As the name suggests, location-allocation is a twofold problem that simultaneously locates facilities and allocates demand points to the facilities. Initially, it may appear that all location-allocation analyses solve the same problem, but the best location is not the same for all types of facilities.

Which is empty in the location allocation Class?

This network analysis class stores the network locations used as the candidate locations from which the actual locations will be chosen from in location-allocation analyses. When a new location-allocation analysis layer is created, the Facilities class is empty.
