一种基于云模型的网络态势综合评估方法

针对网络态势评估中存在的模糊性、随机性和指标量化不统一等问题，提出了一种基于云模型的网络态势综合评估方法。综合考虑实数型、区间型和模糊型指标并统一用云模型量化表示，采用主观与客观相结合的赋权方式，并利用云相似性理论进行网络态势综合评估。对通信网络态势评估的实例分析表明，该方法能够合理地实现网络态势的定性及定量评估，并且保留了评估过程中的不确定性。

A network situation integrated assessment method based on cloud model

In order to solve the problem of fuzziness,randomness and different standards of index quantifica-tion in network situation assessment,an integrated method for assessing network situation based on cloud model is proposed. Real number,interval number and fuzzy number are all expressed by cloud model,and similar cloud theory is utilized in network situation integrated assessment with integrating subjective and ob-jective weights. Example analysis for communication networks shows that the proposed method can achieve rational network situation assessment qualitatively and quantitatively, and retain the uncertainty in the process of situation assessment.
