The Asymmetric information among different entities can contribute to the imbalance between supply and demand in agricultural supply chain. Negotiation is an effective method to address information symmetry. Many researchers can be found in the literature on agent-based negotiation in industrial supply chain, but very few in agricultural supply chain, primarily because of the interior instability. This paper presents an agent-based negotiation framework for agricultural supply chain to address the information symmetry by introducing the third party logistics. The third party logistics, with more functions than a traditional broker, integrates logistics services and intermediary services to guarantee the relative stability in dynamic agricultural environments. A negotiation interaction process is also designed to facilitate the interaction among these agents. Finally, a case is used to validate the proposed framework.@en

Agricultural supply chain is in general open and dynamic attributed and negotiation is a key strategy to realize collaboration among different entities involved. However, traditional static and offline negotiation strategy may not function well, an agricultural supply chain centered on third party logistics will provide a new collaborative relationship among agricultural materials suppliers, agricultural cooperatives, farmers, agricultural products demanders and third party logistics providers. This paper proposes a novel adaptive negotiation strategy for agricultural supply chain centered on third party logistics. The negotiation strategy consists of an evaluation function in terms of integrity and risk preferences, a concession function in terms of concession preference, time and resources, and a generation function in terms of opponent’s behaviors. Afterwards, an procedure was proposed to solve the negotiation strategy. Finally, a simulation experiment was employed to verify the effectiveness of the negotiation strategy. @en
