AddFullOptimization

Overview

This example app demonstrates the following features:

• Add an optimization with custom configuration parameters, orders with different fields set, multiple vehicles with different constraints set; display the solution on the map.

How to use the sample

When you run the example app, an optimization will be saved, the solution will be returned and showed on map.

How it works

1. Create a vrp::OrderList and add the orders to it. Each order needs to have a customer set; you can either add a new customer and then set it to the order, or you can use a previously created customer (see Get Customer example)
2. Create a vrp::ConfigurationParameters and set the desired parameters.
3. Create one vrp::VehicleConstraints for each vehicle and set them to a vrp::VehicleConstraintsList.
4. Create a vrp::Optimization, set the desired fields and the objects created at 1.), 2.) and 3.) to it.
5. Create a ProgressListener, vrp::Service, and a vrp::Request that will be used for traking the request status.
6. Call the addOptimization() method from vrp::Service using the list from 5.), the vrp::Optimization from 4.) and the progress listener.
7. After adding an optimization, check whether the associated request has reached the finished status. Once completed, you can retrieve the optimization results by calling the getSolution() method, which returns a vrp::RouteList containing the generated routes.

To display the orders and routes on the map

1. Create a MapServiceListener, OpenGLContext and MapView.
2. Create a LandmarkList, CoordinatesList using the vrp::OrderList from above.
3. Instruct the MapView to highlight the LandmarkList from 2.) to print the orders, departures and destinations.
4. Create a PolygonGeographicArea from the CoordinatesList and instruct the MapView to center on it.
5. Create a MarkerCollection of type Polyline for each route and add the routes shapes to them.
6. Set the newly created MarkerCollection in the markers collections of the map view preferences.
7. Allow the application to run until the map view is fully loaded.
