A model of safety information radiation of aviation maintenance applied complex networks

为减少航空维修差错率和研究安全信息在复杂网络上辐射的性质和规律,基于复杂网络的相关理论,针对航空维修安全信息在维修人员中的辐射进行研究.通过构建安全信息辐射模型,定义节点间以安全信息为媒介的辐射规则,基于改变维修人员的本质安全度和改变网络结构,动态考察网络中节点状态的变化.从微观层面模拟节点之间交互时,不同本质安全度的人员比例和不同网络拓扑结构对安全信息辐射范围和周期的影响.计算机模拟表明:维修人员的不同本质安全度和网络结构在很大程度上影响安全信息的辐射,提高维修个体的本质安全度有利于安全信息的辐射.

To reduce the aviation maintenance error rate and study the properties and rules of aviation maintenance safety information radiation on the complex network, we study the aviation maintenance safety information radiation in the maintenance personnel based on the theory of complex network. By building a safety information radiation model and defining the radiation rules between nodes through the medium of safety information, dynamic inspect the transformation of the node status in network based on changing the inherent safety degree of the maintenance personnel and the network structure. We analyze the influence of personnel proportion of different inherent safety degree and different network topology structure on the scope and period of safety information radiation when simulate the interactive between nodes on a micro level. With the help of computational simulation, it results that the different inherent safety degrees of the maintenance personnel, as well as the difference of network topology structure, have a lot of impact on safety information radiation. It is beneficial for the safety information radiation to improve the inherent safety degree of the maintenance personnel.
