AddOptimWithOrderFields

Overview

This example app demonstrates the following features:

• Add an optimization with orders that have all the fields set and display the solution on the map.

Create an optimization where for each order can be set:

• the descriptive fields:
  • name
  • address
  • email
  • phone number
• the restrictive fields:
  • the type: pick up or delivery
  • the number of pieces, weight, and cube that have to be picked-up from it or delivered at it
  • the service time: how much time does the vehicle stay at this order to do its job (ex: to unload the pieces)
  • the time window within which the order must be visited
  • the revenue which has to be received from this order

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::Order for each order that has to be visited, set its fields, and then add it into a vrp::OrderList.
2. Create a vrp::Optimization and set the list created at 1.) to it.
3. Create a ProgressListener, vrp::Service, and a vrp::Request that will be used to track the request status.
4. Call the addOptimization() method from vrp::Service using the request from 3.), the vrp::Optimization from 2.), and the progress listener.
5. After adding the optimization, monitor the request until it reaches a finished state. Once completed, 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 and PolygonGeographicArea.
3. Instruct the MapView to highlight the LandmarkList from 2.) to print the orders, departures and destinations.
4. Instruct the MapView to center on the PolygonGeographicArea.
5. Create a MarkerCollection of type Polyline and add the route's shape to it.
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.
