摘　　要：在现有的网格经济模型和在线信誉系统的基础上,提出了基于拍卖机制的网格在线信誉系统模型。该模型侧重于保护资源提供者,为资源提供者提供了贡献与共享资源的动机,吸引更多更好的资源加入网格,实现资源优化分配。保证交易双方均获取最大利益,有利于网格资源的市场管理及供需均衡。并以市场为平台,构建一种新的网格信任模型,由交易事件和衰减函数共同驱动信任度的在线更新,并引入激励机制,尽可能增强信任模型的合理性和可操作性。Based on existing grid economic model and online reputation systems, the online reputation systems model is presented based on auction mechanism, which stresses to protect grid resource provider, The motivation of resources contribution and share for resource providers is provided, and better resources is attracted to join for achieving the resource optimal allocation. The resource management model guarantees maximum benefits for both transaction sides, so it contributes to the market management of grid resource and balance between supply and demand. To establish a new trust model under the grid environment based on the market platform in the same time make use of transactions combined with decay functions to drive on-line update of the trust, and an incentive mechanism is introduced to enhance the rationality and operability of the trust model.
