In this research, we are studying the possibility of
contribution in solving the Vehicle Routing Problem With Time
Windows(VRPWTW), that is one of the optimization problems of
the NP-hard type. This problem has attracted a lot of attention now
be
cause of its real life applications. However, there is still no
algorithm that provides us with the perfect solution to this problem
because of the complexity of polynomial time. This means that the
time of the solution to the VRPWTW is growing steadily with the
increase in the number of nodes .All the used algorithms have just
given solutions that are close to the optimal one.
