摘　　要：为了解决主观信任的模糊性和管理主体之间信任关系的动态性,提出了一个基于模糊决策理论的评估模型。该模型针对成本-效益型方案提出,利用模糊理论处理信任关系的不确定性,使用特征向量法计算信任权重,同时建立优属度模糊矩阵对方案进行信任评估。试验结果表明,该模型是可行有效的。To solve the fuzziness of subjective trust and manage the dynamic relationship between trusts,a assessment model based on fuzzy decision theory was presented.Aiming at the cost-benefit scheme;fuzzy theory was used to deal with the uncertainty caused by trust relationship,the trust weight was calculated by using feature vector method,mealwhile the optimal fuzzy matrix of degrees was establish ed to evaluate the scheme.Experimental results show that the model is feasible and valid.
