摘要
针对当前光纤通信网络风险评估指标多,建模效率低,评估精度差等不足,提出一种因子分析法的光纤通信网络风险评估模型。首先构建光纤通信网络风险的评估指标,然后采用因子分析法优化评估指标,减少评估指标的维数,最后采用支持向量机建立光纤通信网络风险评估模型,并将其应用于具体光纤通信网络系统的风险评估中,结果表明,本文模型实现了评估指标的约简,可以准确描述评估指标与风险值间的变化关系,获得了十分理想的光纤通信网络风险的评估结果,有效保证了光纤通信的安全。
In order to solve the shortcomings of many risk assessment indicators,low modeling efficiency and poor evaluation accuracy,this paper proposes a risk assessment model of fiber optic communications network based on factor analysis method. Risk evaluation index of optical fiber communication network is constructed firstly,and secondly the factor analysis method is used to optimize the evaluation index to reduce the dimension of the evaluation index,the support vector machine is used to establish optical fiber communication network risk assessment model and its use in the risk assessment of the specific optical fiber communication network system. The results show that,the proposed model can reduce evaluation index,accurately describe the relationship between the index and risk value assessment,and obtain the ideal risk assessment of optical fiber communication network,so it can ensure the safety of optical fiber communication.
