Through this analysis, whose objective is to show how geospatial data science techniques can be applied to solve problems in the logistics sector, the existing relationships between Walmartdistribution
centers and their supply sites were identified and characterized, so that different large commercial chains can evaluate and at the same time improve processes in their respective supply chains.
How was it done?
Hundreds of thousands of mobile device records in the areas where Walmart distribution centers are located were analyzed. This cellular positioning data, which is obtained for a specific location and time period, when analyzed on a large scale, provides insight into the influx of people at each point of interest, in this case, the distribution centers and other commercial establishments in the area in question.
With this information, it was possible to infer patterns of behavior in the logistics chain between the distribution centers and the locations to be supplied, establishing the delivery and reception parties with a count of mutual visits. This made it possible to pinpoint the main and most important relationships between distribution centers and stores.

In order to predict and understand the visits and relationships between Walmart's distribution centers in the state of Florida and the surrounding establishments, the following was performed:
First, the state was divided into five zones: Central, North-east, Northwest, Southeast, and Southwest. Subsequently, the coordinates of the distribution centers and headquarters were defined in order to locate them on a map, establishing each center and headquarters as a registry with its respective geographic information. Using an innovative methodology of creating polygons over the buildings, the perimeters were determined, and finally, with the anonymized cell phone positioning data, it was possible to define the number of people who visited the distribution centers and a location in a given period of time.
