Results of the Capacitated TO Experiment

Results of the experiment contain a set of routes with the lowest expenses. The set includes only the routes that let a vehicle visit every customer serviced by a corresponding site by each specified vehicle type per shipment.

Let us say that we have:

  • 2 DCs
  • 2 vehicle types
  • 4 shipments per period

In this case the experiment will perform 16 iterations one for each combination of a site, the specified vehicle type covering every customer defined in the Sourcing and Paths tables per shipment. As a result, 16 possible routes will be found that offer:

  • Properly configured delivery network
  • Optimized delivery costs (per route generated)

Capacitated TO experiment considers actual roads. The GIS map, however, depicts the results with straight lines by default. Disable the Show Straight toggle button in the Optimization results page to depict actual routes.

The results are available in the dashboard below the experiment's view in the form of statistics, distributed through the pages on the left (each page refers to a certain type of statistics). If required, you can rename, remove a page, or export the content of the page's statistics to MS Excel file.

As the total demand reaches nine digit number (measured in the vehicle's Capacity Unit) within the simulated period, the results provided by CPLEX might become less accurate.

By default the Optimization results page is opened, however, the detailed statistics (from the Custom table group) are available in the pages on the left:

  • Optimization results - this page is opened by default. It shows the result of the experiment with all the possible combinations that meet the predefined requirements in the experiment parameters:
    • Source - the site the product is shipped from.
    • Vehicle Type - the type of the vehicle delivering the products.
    • Aggregation period - the periods the Experiment duration is divided into. Demand is aggregated within this period to later be shipped at the end of it.
    • Destinations - the customers expecting the products.
    • Solution Type - the type of solution offered:
      • Optimal - the optimal solution in terms of costs and the data provided to the experiment.
      • Direct - the type of shipments made directly to a certain customer. Demand of this customer (within the Experiment duration period or within a custom period created if Number of shipments is set) exceeds the capacity of the vehicle type used to deliver the products. For example: the vehicle's capacity is 100 units, and the customer's demand is 230 units within this shipment period. We will have 2 direct shipments to this customer, i.e., two trucks will deliver 200 out of the demanded 230 product units. The rest of this customer's demand will be considered by the experiment to design the delivery network.
      • Terminated by User - experiment was not finished, User stopped experiment execution.
      • Time Limited - experiment stopped because it ran out of time, allotted to it by the Optimization time limit per site, sec. parameter.
    • Show Straight - defines the graphical representation of the path on the map. Disable the toggle-button to depict the path as an actual route.
  • Generated Paths - Shows detailed statistics on the routes that were generated by the experiment.
  • Generated Path Segments - Shows detailed statistics on the segments of the generated routes that were created by the experiment.
  • Skipped Customers - Shows detailed statistics on the customers that were not included in the generated route(s).

To see experiment results

  1. Run the experiment.
  2. Once the experiment is completed, a new Result item will be created in the TO experiment branch.

  3. Navigate to the Optimization results page below the experiment view to analyze the results.
  4. Click a record to have it displayed on the map (visualization of TO results differs).

    By default the connections are depicted with straight lines. Disable the Show Straight toggle button in the Optimization results page to depict actual routes.

  5. Click the Disable the toggle button in the Straight column to see the actual routes instead of the straight lines.
