摘要

TOPSIS 方法通过将不同的方法集合在一起并赋予相同的权重来识别传播影响节点，而不考虑不同方法对不同场景有效的物理现象。本文通过引入级联模型来衡量目标节点的影响力，提出了一种加权 TOPSIS 方法，将节点的级联影响能力考虑到 1%，从而计算出权重。九个实际网络的实验结果表明，与传统的 TOPSIS 方法相比，WTOPSIS 的平均准确率提高了 4.471%。

Identifying node importance for networked systems in terms of the cascading model

The TOPSIS method identifies the spreading influences nodes by gathering different methods together with equal weights regardless the physics that different methods are effective for different scenarios. In this paper, by introducing the cascading model to measure the target node's influence, we present a weighted TOPSIS method by taking into 1% nodes cascading influence ability to calculate the weight. Experimental results for nine real-world networks show that, comparing with the traditional TOPSIS method, average speaking, accuracy of the WTOPSIS could be enhanced by 4.471%.
