摘　　要：针对动态综合评价需要考虑被评对象的稳定性问题,提出了一种综合考虑指标权重、时间权重和稳定性的动态综合评价模型。定义了稳定因子来表征被评对象指标的稳定程度,采用离差最大化的方法确定指标权重,提出了一种基于极小范数时间权重确定方法。将所提模型应用于军事IP网络评价,结果表明该模型能够把被评对象的稳定性反映到评价结果中。The stability of evaluated unit need be considered for dynamic comprehensive evaluation. A model of dynamic comprehensive evaluation is proposed which considers attribute weight, time weight and stability factor. The stability factor is defined to denote the stability degree of evaluated unit. The attribute weight is obtained u- tilizing the method of the maximal deviation. A method of minimum norm is proposed to get the time weight and the process of calculation is introduced. The proposed model is applied to the evaluation of military IP network and the result is affected by result attribute stability.
