| 摘 要： | 针对网络性能评估中存在的模糊性和随机性问题,采用云模型和熵值理论,建立了基于云模型和熵权的网络性能综合评估模型;采用熵权方法计算各指标权重,为权重确定提供理论依据;采用云模型理论实现评语与评估指标值之间的不确定映射,保留了评估过程中的随机性。以VoIP网络为例采用仿真的方法对模型进行验证,结果表明该模型与普通模糊综合法相比不仅能得到正确的评估结果,而且能得出其概率值。

| Abstract: | The network performance comprehensive evaluation model based on the cloud model and entropy theory was presented to solve the fuzzy and random problem in performance evaluation.The entropy weight method was used to compute the evaluation factors' weights.The method makes the weight determination reseanable.The cloud model was used to realize the uncertain map between comment and evaluation factor value.The method keeps the uncertainty in evaluation.A case study using simulation method was implemented in VoI... |
