摘　　要：为解决工程中失信风险在动态承制单位网络中的风险传播特性问题,通过复杂网络理论为基础研究承制单位在网络中的关联特性,设计具有动态性、优先性和区域性三大特征的承制单位关系网络模型,在此基础上采用SIRS模型进行风险传播模拟。实验分析发现SIRS变化率对风险传播的规模和速率较大,初始化感染节点比例将会影响到风险传播速度,模拟数据可以反映出现实世界中风险在承制单位之间的扩散,这些传播特性为工程应用奠定了基础。In order to solve the risk propagation characteristics of the risk-free credit risk in the dynamic contractor network,the complex network theory is used to study the related characteristics of the contractor in the network,and the design has three characteristics: dynamic,priority and regional. The unit relationship network model is adopted,and on this basis,the SIRS model is used for risk propagation simulation. The experimental analysis found that the rate of SIRS change rate is large and the rate of risk spread. The proportion of initial infection nodes will affect the speed of risk propagation. The simulation data can reflect the spread of risks in the real world between the contractors. These propagation characteristics are Engineering applications laid the foundation.
