【摘要】：随着现代农业的不断发展,农业供应链管理(Agriculture Supply Chain Management,简称ASCM)系统逐渐成为农业发展的核心。利用网格技术构建农业供应链管理系统,充分发挥网格的分布性、共享性、安全性等特征,使得位于不同地区的农业供应链参与者都能够获取、发布、更新、删除农业生产、加工、存储等过程中的信息,提高农业供应链管理信息共享水平,增加农业供应链的增值空间。ASCM系统在网格上执行仿真任务时,网格平台会根据需要的服务从相应属性的资源分类树(resource category tree,简称RCT)上找到合适的网格资源,从而实现资源的有效利用。网格资源作为网格系统运行的基础,其组织和管理尤其重要,而农业供应链管理网格系统不但与网格资源的组织有关而且还与网格资源的类别、性能、可靠性等有很大关系。基于此,本论文在ASCM系统网格仿真平台服务调度的研究中,提出了基于主属性聚类的网格资源管理算法。首先对加入网格的资源进行属性分析,找出资源的主要属性,然后把资源在各个主属性上的投影组成一个RCT。通过对RCT进行有效的组织和管理,使得其具有对负载的自主演化能力、网格资源的动态维护能力、高度的容错性等。在虚拟组织(Virtual Organization,简称VO)中,各个资源分类树向RCT索引服务(RCT index service,简称RIS)发送RCT的入口信息以及RCT的总体信息。RIS负责和其他的VO进行信息交互,提高资源的查找效率。通过上述对农业供应链管理网格仿真平台的资源进行有效管理,以及对网格资源分类树的HR节点进行备份操作,从而使HR节点出错时,备份节点能够快速的接替HR的任务,实现RCT的有效运作。
[Abstract]:With the continuous development of modern agriculture, agricultural Supply Chain management system has gradually become the core of agricultural development. The grid technology is used to construct agricultural supply chain management system to give full play to the distribution and sharing of grid. In order to improve the level of information sharing in agricultural supply chain management, the participants in agricultural supply chain in different regions can obtain, publish, update, delete the information in the process of agricultural production, processing, storage and so on. When increasing the value-added space of agricultural supply chain .ASCM system performs simulation tasks on the grid, the grid platform will find the appropriate grid resources from the resource classification tree resource category tree (RCTs) of the corresponding attributes according to the services needed. As the foundation of grid system, the organization and management of grid resources is especially important. The grid system of agricultural supply chain management is not only related to the organization of grid resources, but also related to the types of grid resources. Performance, reliability and so on are very important. In this paper, in the research of ASCM grid simulation platform service scheduling, a grid resource management algorithm based on main attribute clustering is proposed. Find out the main attributes of the resource, then project the resource on each main attribute to form a RCT.Through organizing and managing the RCT effectively, it has the ability of independent evolution to the load and the dynamic maintenance of the grid resource. In virtual organization, each resource classification tree sends RCT entry information to RCT index service RCT index service and the overall information of RCT. Ris is responsible for exchanging information with other VOs. Improve the efficiency of resource lookup. Through the above, we can manage the resources of agricultural supply chain management grid simulation platform effectively, and backup the HR node of grid resource classification tree, which makes HR node go wrong. Backup node can take over HR task quickly and realize the effective operation of RCT.
