摘　　要：利用P2P技术对虚拟物流资源组织与检索问题进行描述和求解,提出了基于半对等结构的虚拟物流资源分布式组织架构,构造了一种改进Chord的虚拟物流资源组织覆盖网络结构,给出了该覆盖网络的构建方法、结点动态管理方法以及基于该网络结构的虚拟物流资源注册与检索方法,满足了虚拟物流资源组织的动态性、分布性、自治性、可扩展性、较高可靠性以及资源的有效快速发现等方面的要求,为虚拟物流系统建设提供了一种新的网络实现模式。This thesis expounds and solves the problem of virtual logistics resource organization and retrieval is expounded and solved with P2P technology,puts forward a distributed virtual logistics resource organization framework based on semi-P2P structure,constructs a virtual logistics resource organization coverage network architect based on an improved chord,and presents the coverage network construction method,dynamic node management method,and the logistics resource registration and retrieval methods on such network architect.The research provides a new mode of establishing the network of the virtual logistics system,which meets the requirements as dynamics,distribution,autonomy,extendibility,highly reliability on virtual logistics resource organization and the availability of searching for logistics resource.
