Abstract: Cascading failures in coupled map lattices with Harmonious Unification Hybrid Preferential Model (HUHPM) were investigated through simulation analysis methods in this paper. Two attack strategies: deliberate attack and random attack were adopted in this fixed node number network. According to simulation result, the HUHPM network has better robustness in random attack than in deliberate attack. In addition, the hybrid ration has an important effect on cascading failures of the HUHPM network. In the deliberate attack case, the network became more robust to deliberate attack with the increasing of the random preferential attachment. But in the random attack case, the network became more robust to random attack with the increasing of the deterministic preferential attachment. Therefore, in practical applications, the robustness of HUHPM network can be enhanced by tuning the hybrid ration.
