According to the subjectivity of trust evaluation of grid resources,a model of resources trust audit is introduced.The method of exception judgment to the trust evaluation value of resources is introduced,based on the judgment,exception results are traced,and the main factor on every exception value are found.The audit feedback to trust evaluation model is provided.The audit algorithm is described based on the model.The model reduces the influence of biased evaluations to resource by some users and makes trust evaluation value reflect the QoS of resources more exactly,which makes the users make right choices.Experimental results show that the audit model can improve the utility rate of resources,ensure the success rate of scheduling,reduce the average completion time of the task,and improve the stability of system.
