Invulnerability research of logistics network with dynamic recovery strategy based on NK model
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.
