Краткая информация
Creates a centroid (new store location) in the mean geographic center of your customer points.

Использование
-
In most cases, the input Customer Layer will be a Business Analyst customer layer.
-
The Customer Layer must be point features .
-
In ArcMap, the mean store center will be determined based only on the customer points that are within the active study area or analysis extent. If you want to create the store center based on all customer points, make sure all customers are within the analysis extent.
-
You can use this tool to compare the geographic centroid of your customers to your actual store location. Significant distances between the customer center output and actual store location can illustrate problems with existing store locations.
-
You can create a centroid calculated by a weighted value. If you use a Customer Weight Field, , the geographic center is weighted based on the value of each customer point.
-
Use the Make Clusters option if you wish to create simulated store locations based on the distribution of your customers.This allows you to evaluate existing store locations versus optimal locations by being able to visualize your existing store locations versus the possible locations based on your customer distribution.
-
The output created when using Make Clusters option is an excellent input for the Territory Design tool, where a market may contain customers but doesn't contain seed points. This allows virtual seed points to be generated based on customer distribution.
-
The Make Clusters option uses the K-means algorithm for calculating centroids of clusters.
