Abstract
A transition of vehicles into private ownership has led to a decrease of effectiveness of their use. In this case fleet size and structure is often not coordinated with freight flows. That is why in order to make decisions on effective investment of funds it is necessary to apply appropriate optimization models. For this reason in the paper a new flow model for optimization of structure and vehicles use technology while serving given freight flows is proposed. The optimization model uses an investment distribution graph, where a money flow unit is compared to amount of transported freight and to possible income using a particular vehicle type. The optimization model is realized as a computer program that allows carrying out different experiments applying different initial data and helps to determine the most effective solutions in a dynamic market environment. As an example, the authors created a model for three conditional regions and three relatively interchangeable types of vehicles. Results of one of the experiments are presented in the paper.
