Abstract: The article presents a transport model of grain transportation between the Russian regions. Grain export transportation from suppliers regions to Russian seaports are also considered in transport model. There are discussed the grain annual transportation by railway, having unified tariffs for grain transportation between Russian regions. Model calculations are performed on 2016 year statistics. The following sea ports: Novorossiysk, Tuapse, Taganrog and Vladivostok are used for compiling grain transportation routing. Grain surpluses and deficits indicators in the Russian regions are the input to transport model and are collected from the resources and grain use 2016 year balance. Russian seaport annual capacity for grain transshipment and tariffs for grain transportation between Russian regions are also input to transport model. As a software tool transport model uses the classic transportation task and is implemented in program LPSOLVE. Transport model calculation results can be used for grain and transport companies, to provide an effective grain routes as in consumers regions and for export. Russian seaport annual opportunities for grain transshipment are treated in transport model as grain shortages in the city associated with the port and are added to the grain shortages list of grain recipients regions.
