Center of Gravity Plus (Lat, Lon)

This node can be used to calculate the optimal weighted centers of your customers. You can adjust the importance of the three criterias: weight, volume and revenue in the parameter section. In general, the absolute height of values in a column (weight, volume, revenue) has no influence on their absolute importance (regarding the other criterias). Optimization target is to minimize the weighted distances.
You can use this node to get an indication where should search for new warehouses hubs, distribution centers etc.
For this node one input table is needed. The table should contain all location coordinates, for which a center of gravity should be calculated. A location could be for example a customer, supplier, production plant or something else. Please specify the overall number of centers, distance unit, importance weight, volume and revenue in the configuration dialogue.

In case input and output data need to be saved on the Log-hub Platform, please set save scenario flag to true, fill the workspace id for the workspace in which the scenario should be saved, and give name to the scenario. In case existing scenario should be overwritten, set the overwrite scenario flag also to true, otherwise leave to false.

To use this node you need an API Key from Log-hub Supply Chain Apps. This key you can generate with an Supply Chain Apps Pro Account. More information you can find on www.log-hub.com.
