In this study we expressed oil logistics procurement of crude oil refinement and sale of oil product, as a network model. The oil logistics network model is composed of two sub-models. One is a crude oil and oil products transportation model, and the other is a necessary tonnage estimation model. We formulated the transportation model as a linear planning problem. At first, the volume of oil transportation on each link is decided by this model. And we calculated the necessary number of vessels and the tonnage of the tanker fleet for Japan by the estimation model. After we verified the model, we examined the influence of variation of crude oil price of Middle East. When the price is up, it is expected that the volume of oil from Africa increase considerably. So the ship operating company has to examine the countermeasure. Even if the price is changed, no less than 10 million tonnage of tanker is necessary to transport crude oil from Middle East to Japan. In this case the operating company should consider the scale merit and the conditions for realization.
