摘　　要：针对网络实体间信任关系的不确定性,论文提出了一种基于模糊Petri网的信任评估模型,该模型给出了信任评估的模糊规则,在此基础上利用模糊Petri网与矩阵运算相结合的推理方法,通过并行处理关于一个实体的多个推荐来评估实体间的信任关系。经信任关系评估实例计算可以看出,基于模糊Petri网的推理方法使得信任评估灵活、简单、有效。A trust evaluation model based on fuzzy Petri net is proposed for tackling the uncertainty of trust relationship in the network. The fuzzy rules for trust evaluation in the proposed model are presented first and then a fuzzy reasoning algorithm incorporating fuzzy Petri net with matrix operation is given to evaluate trust relationship by parallel processing of more than one trust recommendations. Finally, an application example of the proposed trust evaluation model is illustrated. It indicates that the trust evaluation model based on fuzzy Petri net achieves a simple, flexible and effective trust evaluation.
