近年来，网络科学的研究趋势正在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。目前流行的多层网络模型有两种：一种是互依网络，另一种是复合网络。我们的目标是构建一种方法，有效地提高复用网络对基于层节点的攻击的鲁棒性。作为实现这一目标的第一步，在本文中，我们研究了现有的链接添加策略的有效性，提出了相互依赖的网络，提高多路复用网络的鲁棒性。通过网络攻击仿真，我们表明，策略链路添加可以有效地提高多路复用网络的鲁棒性。此外，链接添加策略建议是有效的，特别是当大量的节点被攻击。
Recent research trends in network science are shifting from the analysis of single-layer networks to the analysis of multilayer networks. In particular, the robustness of multilayer networks has been actively studied. There exist two popular multilayer network models: one is interdependent network, and the other is multiplex network. We aim to construct a methodology for effectively improving the robustness of multiplex networks against layer node-based attack. As the first step to achieve this goal, in this paper, we examine the effectiveness of existing link addition strategies, which are proposed for interdependent networks, for improving the robustness of multiplex networks. Through the network attack simulations, we show that the strategic link addition can effectively improve the robustness of multiplex networks. Moreover, link addition strategies are suggested to be effective particularly when a large number of nodes are attacked.
