中文摘要：

任务协作分配和决策机制对于企业的供应链管理具有重要意义。采用基于合同网进行协作的Multi-AgentSystem（MAS）方法建立了混合式供应链体系结构。引入关系网的概念,对合同网中的协商策略进行改进和扩充,构建了改进合同网的招标投标模型,通过对招标信息进行分析,建立了评估决策机制。通过计算实例验证所提方法的正确性和有效性。结果表明,采用改进的合同网能大大减少通信量和协商时间,节约系统资源,降低供应链管理成本,提高系统效率,此外采用MAS方法可以使供应链系统具有很好的可扩展性和可重构性。

英文摘要：

Task allocation and evaluation decision approach have significant impact on supply chain management.A supply chain with hybrid structure is developed using contract net-based multi-agent system（MAS）.The improved contract net-based bid model is presented through by introduction of relationship net and improvement of negotiation strategy of contract net.The evaluation decision approach is explored through analyzing bid information.The correctness and effectiveness is validated by a case study,and the results shows that the communication volume,negotiation time and management cost are quietly decreased,the system resources are saved,and system efficiency is increased through the developed system.Moreover,the supply chain with multi-agent system has better expansibility and reconfiguration.
