最近的研究 趋势 网络科学的研究已经从单层网络的分析转向多层网络的分析。特别是，多层网络的鲁棒性已经得到了积极的研究。两种流行的多层网络模型存在：相互依赖和多元化。本研究提出多路传输网路之连结增加策略，以提升网路抵抗层节点攻击的强健性。所提出的策略扩展了现有的策略称为随机度间度差（RIDD），这是为了提高相互依赖网络的鲁棒性。RIDD利用层间度差添加链接，而所提出的策略同时利用层间度差和层节点度添加链接。通过对多个网络攻击的仿真，我们证明了所提出的链路添加策略可以有效地提高多路复用网络的鲁棒性。
Recent research trends in network science have shifted from the analysis of single-layer networks to that of multilayer networks. In particular, the robustness of multilayer networks has been actively studied. Two popular multilayer network models exist: interdependent and multiplex. This study proposes link addition strategies to improve the robustness of multiplex networks against layer node-based attack. The proposed strategies extend an existing strategy called random inter degree–degree difference (RIDD), which is proposed for improving the robustness of interdependent networks. While RIDD adds links using inter-layer degree difference, proposed strategies adds links using both inter-layer degree difference and degree of layer nodes. Through several network attack simulations, we show that the proposed link addition strategies can effectively improve the robustness of multiplex networks.
