Using Center of Gravity for Supply Chain Analysis and Network Design

____

Select your current cutomers

To get started, you’ll need a list of your current customers and last year’s revenue. Select the data in Excel and link it to the “Addresses” table as shown below. After the data is selected and the link icon on the right turns green, click on the “Calculate” button.

Visualize your data on the map and dashboard

Once the calculation is done, open the map and the dashboard to get an overview about the results. In the sample map below, you’ll notice that the program calculated three centers of gravity: one center is close to Berlin, one center is in the western part, where most of the customers are, and one center is in the south.

Use the Dashboard to analyze the quality of the results

The dashboard provides you with an overview of the most important KPIs. As you can see in the example below, the average distance to the customer and the maximum distance is quite high. If the calculated result does not fulfill your service requirements, you can adjust the number of centers, which in turn would increase the service level.

Adjusting the number of centers

To increase the service level, you can easily adjust the number of centers with the slider control as shown below. After you have adjusted the number of centers, click on the “Calculate” button again to recalculate.

Check the new results

Adjusting the number of centers increases the service level. You can repeat the last two steps until your requirements have been fully met.

Simulate expansions in new regions

You can also use the Center of Gravity App to simulate changes in your demand or possible expansions in new regions. Just add your potential customers with the estimated revenue to your input data and start the calculation again. In the example below you can see a simulated expansion into the French market.
