摘　　要：针对列车通信网络性能评估缺少量化评估的问题,提出了基于云模型和组合赋权法的列车通信网络评估方法。首先,建立列车通信网络性能评价体系和Opnet仿真平台,采用组合赋权法确定综合权重;然后,采用云模型生成评价云,根据综合权重和逆向云算法得到综合云;最后,将列车通信网络性能综合云与评价云进行相似性度量,实现列车通信网络性能的评价。通过算例分析表明,该方法能够客观有效地评估列车通信网络性能,为列车通信网络的性能评估提供了理论参考。In the view of the lack of quantitative assessment in the performance assessment of the train communication network, a train communication network evaluation method, based on cloud model and combination weighting method, was proposed in this paper. Firstly, the performance evaluation system of train communication network and Opnet simulation platform were established, and the comprehensive weight was determined by the combination weighting method;Secondly, the evaluation cloud was generated by the cloud model, and the comprehensive cloud was obtained according to the comprehensive weight and the reverse cloud algorithm;Finally, the similarity between the comprehensive cloud of train communication network performance and the evaluation cloud was measured to realize the evaluation of train communication network performance. The example shows that the method could evaluate the performance of train communication network objectively and effectively, which provides a theoretical reference for the performance evaluation of train communication network.
