| 摘 要： | 在BBV模型基础上，结合方向性和网络演化特性，提出一种有向加权网络模型。引入参数p、q，将节点强度分为入强度和出强度，根据BBV建模思想进行模型择优和演化。理论分析和数值模拟仿真结果表明，该模型的节点出入强度和出入度分布满足幂律指数为2,3]的幂律分布，且通过调节参数可使平均路径和聚簇系数符合复杂网络特性。 |
| 关 键 词： | BBV模型 有向加权网络 边权 节点出强度 节点入强度 |

| Abstract: | This paper proposes a directed weighted network model based on BBV model by culminating with directivity and characteristic of network evolution. It introduces parameters p, q, the strength of a node is divided into in-strength and out-strength, picks over and evolution of this model based on BBV building thought. Theory analysis and numerical value simulation results show that node distribution of out-strength and in-strength with the exponent of 2,3] in this model. Average path and clustering coefficient which are adjusted by parameter can consistent with the characteristics of complex network. |
| Keywords: | Barrat-Barthelemy-Vespignani(BBV) model directed weighted network edge weighted node out-strength node in-strength |
