Abstract: At present existing grid scheduling algorithms ignore the impact of matching between resources and tasks.Based on trust utilization functions and matching conception between resources and tasks，a trust-driven grid job scheduling problem is presented for computing grid.The utility of QoS between tasks and resources consideration are taken into in the scheduling to improve Trust-Relation and TD_Min-min scheduling algorithms.Simulation results demonstrate that the algorithm’s performance is better than TD Trust-Relation，TD_Min-min in the aspects of trust utility，effective resource utility，load balance.

摘要： 针对目前网格资源管理中任务与资源匹配问题的不足，基于信任效益函数与匹配概念，提出了信任驱动的网格调度匹配算法。在调度中同时还考虑了任务和资源效益值，对已经提出的两种信任驱动的网格调度算法进行改进。结果证明：该算法较传统基于的信任驱动调度算法而言，信任效益值，资源效益值，负载平衡和失效服务数等方面有较好的综合性能。
