摘　　要：论文分析了目前网络服务质量综合评价研究现状,通过对比当下主流的网络仿真软件的优缺点,选择OPNET++仿真软件建立网络模型,利用最小二乘法获得最优综合权重并结合标准评价矩阵构建加权标准评价矩阵,计算稳定性、响应时间、利用率三个网络服务质量评价指标,采用改进灰色关联分析-逼近理想值排序方法进行多属性综合评价,为网络性能的优化提供理论指导。实验结果表明,该方法能够有效弥补单一方法在多属性综合评价上的不足之处,提高了评价的准确性。This paper analyzes the current research status of network Quality of Service comprehensive evaluation. By comparing the advantages and disadvantages of the current network simulation software,the OPNET++ simulation software is selected to establish the network model. The least square method is used to obtain the optimal synthesis weights and the weighted standard evaluation matrix is constructed with the evaluation matrix. It uses this simulation software to calculate stability,response time,utilization rate these three network Quality of Service evaluation index,introduces the improved Grey Relational Analysis-Technique for Order Preference by Similarity to Ideal Solution to carry out multi-attribute comprehensive evaluation,and provides theoretical guidance for optimization of network performance. The results of the experiment show that the method can be used to correct the lack of a single method in multi-attribute synthesis,and improve the accuracy of the evaluation.
