Once you have written a description of your problem, you can use Dispatcher classes to model it. This solution process is highly depot based. It is worth introducing a class for depots which encapsulates the composition of the depot, along with methods for improving the solution for a depot. You will also create a RoutingModel class, as in a standard PDP.

Open the example file YourDispatcherHome/examples/src/tutorial/mdpdp_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 code for the problem and you will be able to compile and run it.
