多Agent系统中基于扩展合同网模型的共同配送任务分配研究

In order to solve the problem of dynamic allocation of cross-organization dynamic distribution, this paper proposes a multi-agent common distribution dynamic logistics assignment method based on extended contract network.The extended contract network includes three aspects: the bid strategy based on the "acquaintance" relationship, the multi-agent supply chain alliance bidding strategy and the multi-attribute evaluation winning strategy. Through the "acquaintance" bidding strategy to reduce the number of invalid tenders issued, reduce communication costs; Through the multi-agent supply chain alliance bidding strategy to reduce the contract management agent task portfolio optimization calculation, to enhance the task distribution speed; Through the fuzzy comprehensive evaluation method to establish the cost, quality and time of the three factors comprehensive utility of the largest bid evaluation model, The validity of the task allocation method is verified by a common distribution case of a logistics enterprise in Chongqing. The results show that the method is based on the resource status and willingness of the common distribution members to successfully distribute the tasks fastly and effectively, which achieves the mutual benefit and win-win situation of the common distribution alliance and reduces the cost.
