摘　　要：网格环境下的计算资源具有分布性,异构性,动态性的特征,并分别属于不同的组织,使网格资源管理相对分布式计算环境或集群环境下的资源管理更加复杂。在计算经济模型的基础上,提出了一种基于计算期望的网格资源管理模型。模型将计算任务抽象成对计算期望的描述,以实现灵活高效的网格资源管理和调度。通过可变价格策略,反映了网格内资源的供求关系,并对基于预留的Qos保证进行了初步的讨论。The resource management in grid environment is more complex than it in distributed computing and cluster environment, because the resource are geographic distributed, heterogeneous, dynamic and owned by different organizations. A computing expectation based grid resource management model is presented based on the theory of grid economy model to achieve flexible and efficient grid resource management and allocation. The relationship between demand and supply of resource in grid is demonstrated by the variable Price strategy and the reservation based QoS problem is discussed primarily in the model.
