Pricing Model of National Gas Exports via Pipeline on the Base of Game Theory

One of the most important issues in the field of natural gas export via pipeline is the lack of pricing strategy, and providing an optimum pricing mechanism has always been one of the biggest challenges for gas export contracts. In this paper a pricing mechanism based on Game theory provided. The pricing mechanism has been developed based on cooperation among producing countries, consumers and gas transmitters that in the case of gas-exporting countrie's commitment to it, the interests of these countries will be supplied. So, taking into account the realities of the market and according to the conditions of transmitter country, different scenarios have been compiled and according to it, the modeling is accomplished. The results of the different models in determining price, quantity and optimum tariff for two cooperative and non-cooperative games is that the interest of member countries in cooperative game is far greater than non-cooperative game.
