基于组合赋权-TOPSIS模型的机场时序网络关键节点识别研究
Identification of Key Nodes in Airport Temporal Networks Based on Combined Weighting-TOPSIS Model
为应对机场网络动态调控与应急管理的迫切需求,提出了基于组合赋权-TOPSIS模型的机场时序网络关键节点识别方法。首先,利用小波分析揭示机场网络的周期性特征,构建多层时序网络模型。其次,综合节点的时序度中心性、介数中心性等指标建立综合评价体系,并通过AHP-熵权法耦合赋权策略平衡主客观权重分配。最后,引入TOPSIS方法对节点重要性进行排序,并采用蓄意攻击试验观察节点移除对网络结构和性能的影响。试验结果表明:在攻击初期,节点攻击比例达30%时,最大连通子图降幅达14.0%,高于传统方法平均值8.2%;攻击比例达30%~50%时,网络效率下降91%,较单一指标方法提升破坏效率46.1%;当攻击比例达80%时,网络残余效率降至0.027,远低于其他方法的效率水平。该方法可为机场网络的韧性评估、动态调度优化及突发事件应急管理提供兼具理论创新性与实践可行性的技术支撑。
In order to address the urgent needs of dynamic regulation and emergency management in airport networks, a method for identifying key nodes in airport temporal networks based on a combined weighting-TOPSIS model was proposed. First, wavelet analysis was used to reveal the periodic characteristics of the airport network and construct a multi-layer temporal network model. Then, a comprehensive evaluation system was established by integrating temporal degree centrality, betweenness centrality, and other indicators. An AHP-entropy weight hybrid strategy was adopted to balance subjective and objective weight assignments. Finally, the TOPSIS method was introduced to rank node importance, and deliberate attack experiments are conducted to observe the impact of node removal on network structure and performance. Experimental results show that in the early stage of attacks, when 30% of the nodes are attacked, the size of the largest connected component drops by 14.0%, higher than the average of 8.2% under traditional methods. When the attack ratio reaches 30%~50%, network efficiency decreases by 91%, improving attack effectiveness by 46.1% compared to single-indicator methods. When 80% of nodes are removed, the residual network efficiency falls to 0.027, significantly lower than that achieved by other methods. This approach offers both theoretical innovation and practical feasibility for airport network resilience assessment, dynamic scheduling optimization, and emergency management in response to unexpected events.
