The flows of oil in function of supply and demand chain optimisation

Over the last forty years, one of the most difficult transportation policy questions has been the issue of the price of oil and its associated impact on transportation systems. Oil drives a large part of the costs of the production of agricultural, manufacturing, and service industries. Furthermore, as industries have globalized over the last thirty years the low price of oil has been critical in allowing logistics chains to become more and more elongated. The main characteristic of world oil flow lies down in a fact that the line directions for these types of flows are conditioned by formation of oil sources in the world, with reference to the largest producers, exporters and importers of oil. In other words, the most important flows of oil are formed on a direction from a large producer or exporter states, to the major consumer countries. In geographical analysis of world oil flows, data on the largest exporters and importers countries of oil are representing the important indicators of the intensity and the main directions of these types of flows.
