【摘要】：在企业创新网络演化模型的基础上提出节点的创新能力概念,构建企业创新网络级联失效可靠性模型,并对动荡、动态平衡和萎缩3种类型网络进行仿真实验研究。仿真数据表明:随机攻击节点条件下,动荡网络的节点失效率高于其他两种网络,但在攻击度中心性较高节点时动态平衡网络的节点级联失效率要高于动荡网络;随着度中心性变小,动态平衡网络的节点失效率逐渐低于动荡网络,而萎缩网络的节点失效率则一直处于最低;除此之外,如果攻击流介数中心性节点,动荡网络的创新能力损失率一直较高。实验结果表明,动荡网络的网络综合创新能力最高,但是可靠性较低。
[Abstract]:On the basis of the evolution model of enterprise innovation network, the concept of innovation capability of nodes is put forward, and the failure reliability model of enterprise innovation network cascade is constructed, and the simulation experiments of three types of networks, such as turbulence, dynamic balance and atrophy, are carried out. The simulation data show that the node failure rate of the turbulent network is higher than that of the other two networks under the condition of random attack nodes, but the cascade failure rate of the dynamic equilibrium network is higher than that of the turbulent network when the attack degree is higher than that of the central node. As the degree of centrality becomes smaller, the node failure rate of the dynamic equilibrium network is gradually lower than that of the turbulent network, while the node failure rate of the shrinking network is always the lowest; in addition, if the attack flow is centered, the node failure rate of the dynamic equilibrium network is lower than that of the turbulent network. The rate of loss of innovation capability of turbulent networks has been high. The experimental results show that the complex innovation ability of turbulent networks is the highest, but the reliability is low.
