The solutions to the multi-criteria vehicle routing problem, dependent on route length and travelling time of delivery van, are presented in the paper. This type of problem is known as a traveling salesman problem. The artificial immune system is used to solve it in this article. Since there are two variables – route length and travelling time - two methods are employed. They are: Weighted Objectives Method and Pareto Efficiency Method. The results of calculation are compared.
