A game theory approach to analyzing the competitiveness of tariffs on transit container transportation via railroads is proposed. In the framework of the proposed approach the analysis is implemented by solving (finding saddle points in) two games on polyhedral sets of connected strategies of the players with the payoff function being a sum of two linear functions of vector arguments. When Russian Railways compete against all its competitors, finding competitive tariffs and a fair share of the market of transit container transportation is reducible to solving two auxiliary quadratic programming problems. When Russian Railways partners (forms a coalition) with any of its competitors, finding the saddle point of the game is reducible to solving systems of quadratic inequalities.
The proposed approach allows Russian Railways develop substantiated recommendations on changing tariffs, determined by the 10-01 Russian regulation, not only for transit container transportation, but for all railroad freight transportation in Russia.
