Phase 1. Import Scenario and Run the Experiment
In the Capacitated
TO Tutorial we created
routes comprising a succession of customers that will be visited by our
vehicle in a certain order. In this tutorial we will improve
that scenario by adding the working hours of the stores and
the DC that is supplying the stores with
The aim of the Capacitated TO with time
windows experiment is to optimize the existing routes to make
the deliveries fit into the working hours of the customers.
Once you download
and import the Lidl
CTO with Time windows scenario, you may proceed to improving
the experiment parameters.
Download and import the
- Download the scenario.
No internet connection is required, since the scenario is supplied with
the downloaded scenario. The GIS map will appear showing the content of
the imported scenario.
- Explore the connections by clicking the Show filters
button to open the filter options, and then clicking
Show connections button.
The imported scenario contains a supply chain with
stores and one distribution center on the territory of
Let us run the experiment and observe the statistics to have
basic understanding about the supply chain.
Run the Capacitated TO
- Navigate to the experiments
section and click Capacitated
You will be taken to the experiment's view
with its predefined parameers:
- Number of shipments
- the number of shipments you would
like to send within the Experiment
duration period. The current calue is 2, which means that we will have 2 shipments within
2 months, i.e. 1 shipment a month.
- Vehicle types
- the type of vehicle delivering the products. We will be using Vehicle type 2 in this tutorial.
- Travel segment limit
- the maximum remoteness of the network objects from each other in the
specified Distance unit.
- Returning segment limit
- the maximum remoteness of the last customer of the route from the DC
that the vehicle set off from.
- Min vehicle load ratio
for direct shipments
- specifies the minimum amount of products a vehicle can carry as a
direct shipment (shipment made to one customer only). In our case, a
customer must order 76 m3 of products or
more to have a direct shipment. The value is calculated as vehicle capacity (80m3)
multiplied by the parameter's value (0.95).
Run in the toolbar of the CTO
The results will be available in the Result
sub-item of the CTO experiment
Now observe the
the received results
To simplify the comparison of the received results, we will add the Generated Paths table to
the Comparison dashboard.
- Navigate to the Optimization
tab below the experiment view. The result contains 27 routes
for 2 shipments. A route is an optimal combination of segments (paths),
allowing a vehicle visit certain customers in an organized succession.
- Now click any record (we
will click record #2) to display the route with
customers on the map.
You will see a route, which in our case comprises 4
customers: Lovech, Pleven, Svishtov, Ruse (this route may as well
be in any other record of this table). We will
further compare the routes in whcih the Lovech
customer is visited.

available on lines 1 and 15 respectively:
- The Destinations

routes in shipment
- The Cost, USD
shows the cost of this shipment

- Click the Add to
A dialog box will open prompting you to specify the name

That's it we
have completed the first phase of this tutorial. We imported the
scenario, ran the experiment, and analyzed the results. In
the next phase we will try to fit the delivery times into the
working hours of our
