随着经济全球化和电子商务的快速发展,物流管理模式不断变革,物流企业联盟应运而生,合作运输是不确定需求市场下物流运输企业广泛使用的一种运输策略.本文研究了在合作运输策略下物流企业之间的运输合作问题,分别讨论了基于时间的合作运输策略和基于数量的合作运输策略下企业运输合作费用的分摊问题,建立了相应的运输合作博弈模型,利用合作博弈理论,将联合运输的成本分摊问题转换为费用分摊博弈问题.通过对企业联合运输行为的研究,证明该博弈为凹博弈,且核心非空,并设计了属于核心中的费用分摊方案.研究结果表明,合作不仅能够降低企业的成本,还能提高客户服务水平.最后,用数值例子验证了相关结论.
The rapid development of economic globalization and electronic commerce has brought huge transformation of the logistics business management pattern. The theory of logistics alliance arose accordingly. Cooperative transportation is widely used by logistics enterprises with stochastic demand. This paper focuses on cooperative transportation among logistics enterprises under shipment cooperation policy. The cost allocation problem of combining transport policy among enterprises is converted into a cost allocation game based on the cooperation game theory under time policy shipment consolidation and quantity policy shipment consolidation, respectively. Analysis of enterprises' behaviors proves that the cost allocation game is concave, and has nonempty core. The results show that cooperation among enterprises not only reduces the cost of each carrier, but 'also enhances customer service level. And then the findings are illustrated by a numerical example.
