摘　　要：近年来,日益频发的重大突发公共事件给物流网络的运作带来许多风险和不确定性因素,物流网络需要具备更强的抗毁性来应对此类破坏性事件.本文结合NK模型与复杂网络抗毁性理论,提出了具有环境适应性的动态修复策略,并利用网络规模N和节点关系密度K两个重要参数,展开了级联失效与动态修复场景下物流网络的刻画与抗毁性分析.研究表明:1)动态修复策略会给物流网络抗毁性带来双重影响,即动态修复策略不仅会给物流网络造成积极影响,也会造成一定的消极影响.2)参数N与参数K对修复效果有着重要的调节作用,即可以通过调节参数N和参数K来实现更好的修复效果,并以此来提升物流网络的抗毁性.最后,本文结合现实案例,对动态修复策略的现实含义进行详细阐述.总的来说,物流网络与修复策略需要通过相互适应,来实现修复策略本身的优化与物流网络抗毁性的提升.本文将NK模型方法引入复杂网络抗毁性的研究领域,为物流网络抗毁性研究提供了新的思路,为复杂环境下的物流网络风险研究提供了分析方法.Nowadays,more and more frequent major public emergencies add more risks and uncertainty to the operation of logistics network.Logistics networks need stronger invulnerability to cope with this kind of destructive events.NK model and invulnerability theory in the field of complex networks were combined in this paper to propose the dynamic recovery strategy with the characteristic of environmental adaptability.The logistics network in this paper was characterized by network scale N and relationship complexity K.The invulnerability of logistics network in the context of cascading failure and dynamic recovery was studied respectively from the perspectives of N and K.The results showed that:1)The dynamic recovery strategy can make either a positive or negative impact on the invulnerability of logistics network.2)Parameter N and K played important regulating roles in the effect of dynamic recovery.Through adjusting the value of N and K,a better recovery effect and a higher invulnerability of logistics network can be achieved.Finally,the realistic meaning of the dynamic recovery strategy was elaborated in the context of realistic cases.In summary,the mutual adaptation between logistics network and recovery strategy is necessary for the optimization of dynamic recovery strategy and the improvement of invulnerability.In this paper,NK model method was integrated with complex network.It provides a new idea for the research of logistics network invulnerability and an analysis method for the research of logistics network risk in complex environment.
