| 摘 要： | 针对目前网络性能评价中多元指标之间权重难以确定的问题,将信息熵理论应用于网络性能评价中.提出采用熵权方法确定指标权重,进而对网络性能进行评价的方法.为了获取反映不同网络状态的性能数据,采用网络仿真方法获得计算熵权所需的样本.实例表明,信息熵能够客观地反映各指标贡献信息量的大小,基于信息熵的熵权能够客观反映各指标的相对重要程度.

Method of determining VOIP network performance evaluation weight based on entropy weight and network simulation |
| |
| Abstract: | The entropy theory was introduced to solve the problem of determining the weight of multi-variate indexes. The entropy weight was used to determine weight and the performance evaluation method was proposed based on entropy weight method. The network simulation was adopted to derive the samples which could reflect the different network states for computing entropy weight. The case demonstrates that the information entropy can objectively reflect the size of information provided by each index and the entropy weight can objectively reflect the related importance of each index. |
