Abstract: Integrated supply by third-party logistics(TPL) is an effective way to reduce supply chain cost.A key problem of TPL integrated supply is to allocate the supply cost among the suppliers rationally.In this paper, Integrated supply by third party logistics is discussed, a cost allocation model is founded based on cooperate game theory, and the Shapley value method is commended to solve the model.To get over its inherent limitation of evaluation, the EOQ model of integrated supply is adopted, which makes Shapley value method more practicable.Finally, a case is used to prove the feasibility.

Key words: integrated supply, third-party logistics, cooperate game, Economic ordering quantity
