摘　　要：针对目前网格资源调度中忽视信任机制的缺陷,在行为信任模型和能力信任评估的基础上,提出一种信任驱动的资源调度算法TDS。该算法同时兼顾了性能QoS和信任QoS。仿真实验结果表明,TDS算法与传统的基于性能QoS的算法和基于信任QoS的算法相比,在最小完工时间和服务请求提交成功率方面具有较好的性能。Aiming at the limitation of present schedule algorithms in grid that largely ignore the impact of the trust mechanism, based on the behavior trust model and ability trust evaluation, this paper proposes a new trust driven resource schedule algorithm TDS. TDS not only focuses on performance QoS but also pays attention to trust QoS. Situational experiment results show the TDS performs better than Min-min and TD Min-min algorithms at the aspect of least complete time and the ratio of successful request submission.
