Once you have written a description of your problem, you can use Dispatcher classes to model it. Dispatcher is based on IBM® ILOG® Concert Technology and IBM® ILOG® Solver. If you are not familiar with these products, please refer to the Concert Technology and Solver documentation.

Open the example file YourDispatcherHome/examples/src/tutorial/vrp_partial.cpp in your development environment. This file is a program that is only partially completed. You will fill in the blanks in each step in this lesson. At the end of this lesson, you will have completed the program code for modeling the problem. At the end of the next lesson, you will have completed the code for solving the problem and you will be able to compile and run it.

You will use object oriented programming techniques to write this program. In this lesson, you create the RoutingModel class, which is used to build the model of the vehicle routing problem. In the next lesson, you will create the RoutingSolver class, which is used to solve the problem, and you will also create the main function and compile and run the program.
