Revealing how the interdependency between different networks affects the load-induced cascading failures is a new interesting topic recently. A new cascading failure model for interconnected network system is introduced in this paper, in which the loads of the failed nodes can be transmitted between different layer networks or among each layer network, the ratio is adjusted with a defined parameter Tf which can be viewed as a measure of coupling strength. Based on the proposed model, we find that under different attacking strategies and different value of Tf, different coupling types have different effects on the robustness of interconnected network systems. We mainly focus on the robustness of interconnected network with random coupling under intentional attack, we find there being a threshold Tf*, when Tf Tf*, if the capacity redundancy of interconnected network is low, increasing Tf tends to enhanc...
