The article deals with the problem of modeling complex systems management, linking refineries factiries, refined products transportation and final sale items (gas station). This problem has been analyzed in two ways. First, a comparison of agent-based modeling with traditional styling rigidly constructed system, in which each element is described by equations and between the elements of a model are set interaction. Under this approach, product streams are calculated in terms of a certain optimization criterion of these flows. Secondly, in the conventional model is considered vertically integrated structure, whereas the agent-oriented modeling - a distributed system in which elements interact independently acting in maximizing their own, and not the general corporate revenue.
