The paper aims to study business competition strategies for cargo freight orders in Sino-Europe cargo train services from the perspective of conflicts by using Graph Model for Conflict Resolution and to construct the conflict resolution model applicable for the business services such as Chongqing-Xinjiang-Europe cargo train, Suzhou-Manchuria-Europe cargo train and Kunsan IT. It uses TOPSIS to assess the transportation efficiency of cargo trains, to study the conflicts in the competition for cargo routes, to determine decision maker’s preferences and to analyze the rational strategies by decision makers in the profit competition with Graph Model for Conflict Resolution. A sensitivity analysis is given to show that any change in decision makers爷 preferences may have impact on the results of Graph Model for Conflict Resolution. The study indicates that Sino-Europe cargo train services may effectively get more cargo freight orders by reducing prices in the competition for business orders and that those less efficient cargo train services may take an upper hand over others in competing for cargo freight orders by lowering the transportation prices. The study provides cargo train services with business competition strategies in the conflicts of profit-seeking and give potential customers more effective strategies to choose more efficient cargo train routes. Governments may also be guided to regulate and improve the efficiency of the market.
