【摘要】 本文首先探讨了数字矿山框架的不足和当前煤炭企业信息化建设中遇到的问题,利用企业网格的优点,给出了基于企业网格的数字矿山模型EGBDM并讨论了其特点与需求。在此基础上,定义了煤炭企业网格e-Mine并设计了其拥有资源层、管理层、服务层和应用层的四层体系结构。在e-Mine体系结构下,详细研究了煤炭企业资源虚拟化机制,对煤炭企业资源进行建模,实现了其网格服务化封装并根据煤炭企业现有的管理模式提出了e-Mine资源三层混合模型组织结构和相应的2阶段资源注册／检索算法。针对煤炭企业日常安全生产任务的QoS需求,结合时间Petri网与工作流网提出了时间工作流网TWF_net作为e-Mine下任务的工作流建模工具并实现了其流程基于WS-BPEL语言的服务组合描述；给出了考虑任务优先级且带有QoS保障的任务调度算法。文章最后设计了e-Mine的原型系统,基于GridSphere框架实现了e-Mine网格门户并对煤炭企业特有的遗留资源网格服务化封装技术进行了研究。更多还原

【Abstract】 This paper firstly discussed the problems in the digital mine theory and coal enterprise informatization. Take into account the advantage of the enterprise grid, the Enterprise Grid based Digital Mine (EGBMD) model was proposed and the characteristic, special need of it were also discussed. Based on these, we defined the coal enterprise grid which is named e-Mine has a four layers architecture that is resource layer, management layer, service layer and application layer. Under the e-Mine framework, we studied the coal enterprise resource virtualization mechanism detailed. We firstly gave the coal enterprise resource modelling and realized the service encapsulation of it, then put forward the resource three layers hybrid model organization structure and the responding two step resource registration/search algorithm also advanced. For the QoS requirement of the task in the coal enterprise, we proposed the TWF_net which is take advantage of the time Petri and WF_net as the workflow modeling tool and realized the workflow description by the WS-BPEL. The QoS provision task scheduling algorithm for the workflow was also presented. At last, we designed and realized the prototype system of the e-Mine. The Portal was realized based on the GridSphere and the service encapsulation techniques for the coal enterprise existed system were also studied.更多还原
