摘　　要：由于网络评价过程中需要考虑动态性和稳定性等因素,提出一种考虑运行水平与稳定性的网络动态综合评价方法。利用"三次综合"的思想,分别突出评价指标重要性、统计时刻重要性和网络稳定重要性。提出一种基于极小范数的时间度确定方法来集结不同时刻的评价值,提出基于最小差异度的稳定度作用模型,确定网络稳定性对最终评价结果的影响。实例分析表明,所提方法能够在评价结果中有效地体现评价过程的动态性和网络性能指标的稳定性,使得评价过程更加全面,评价结果更加准确。As the process of network evaluation is dynamic and the steady of network need be considered, a dynamic comprehensive evaluation method of network considering operational level and stabiiiby is proposed. The idea of ＂thrice integration＂ is presented to give prominence to performance index, the time of statistic and stability of network sequentially. A method of minimum norm is proposed to get the time weight and integrate the evaluation re- suits of different time based on time orness. An influencing model of stability is proposed based on the dissimilarity of the first evaluation result. The model could decide the impact degree of stability to the final evaluation result. Finally, the example proves that the dynamics and the steady of network could be reflected in final evaluation result effectively.
