Phase 1. Configure and Run GFA with Roads Experiment

In the GFA Tutorial we created a supply chain scenario from scratch, populated it with customers, demand, and executed the GFA experiment. In this tutorial we will use that scenario to later compare the received results of the two greenfield analysis experiments.

The aim of the GFA with roads experiment is to find DC location(s) considering the population of the cities and the actual roads connecting them.

Once you download and import the My Supply Chain (GFA with Roads) scenario, you may proceed to configuring the experiment parameters.

Configure parameters of the GFA with roads experiment

  1. Navigate to the experiments section and click GFA with roads experiment.

    You will be taken to the experiment's view with its settings.

    Now we can set the experiment a task to find the best locations for a certain quantity of DCs, since we already know the optimal number of DCs from the result of the GFA experiment.

  2. Click the Number of sites field and type in 3.

  3. Set Product measurement unit to pcs, since we set our product to be measured in pieces in this scenario.

  4. Filter the cities to consider by specifying the Minimum population of 15000 people.

  5. Click the toolbar Run button in the experiment's view to run the experiment.

    Once the experiment is completed, a new Result item will be created in the GFA with roads experiment branch. You will be automatically taken to the new item's page containing the experiment results.

Let us take a closer look at the Result page. The distribution centers (DCs) were placed in the most advantageous locations, considering actual roads and population of the cities.

Since the experiment considers actual roads we can visualize them on the GIS map.

Enable paths on the GIS map

  1. Click the Show filters button to open the filter options.
  2. Now click the Show connections button.
    The paths will be depicted as straight lines. Let anyLogistix download the data. This may take some time depending on the internet connection speed and the number of routes. Once anyLogistix applies the downloaded information to our map, we will be able to see the actual routes, which connect customers to each distribution center. The GIS map sourcing paths will change their shape in accordance with the available roads leading from the warehouses to the customers.

The result seems to be similar to the one received by the GFA experiment, but if we take a closer look at the locations of the three DCs, we will see that they differ, which also affects the set of customers for each DC.

Hover mouse cursor over the image below to see the difference.

Now let us examine each location individually.

Check DC locations

  1. We shall start with the DC in the western part of the United States. Place mouse cursor over the DC icon to center the map while zooming in. Scroll mouse wheel to zoom in.

    You will see that it is located in the center of Los Angeles. Now compare it to the location offered by the GFA experiment, you will see that it is located too far from the closest highway/city.

  2. Now we will check the rest of the two DCs. Zoom in to the DC located in the middle.
    This DC is located in Dallas, while the DC offered by the GFA experiment is located too far from the closest highway/city.

  3. Zoom in to the DC located in the eastern part of the United States.
    You will see that is it is located in New York, while the GFA offered DC is not far from Moscow.

As we can see, the DC locations offered by the GFA experiment require further adjustment as they are too far from the required infrastructure, while DCs offered by the GFA with roads experiment are located in the center of the cities. You can move them to any surrounding area if required.

That's it. We have completed the GFA with roads tutorial.

Now we can move on to specify the price of the product, cost of opening a warehouse and the cost of processing the outgoing shipments to further optimize the supply chain.
