基于微分进化算法的消息传播网构建

Construction of Information Dissemination Network Based on Differential Evolution

某事件发生时,除消息以广播的方式通知相关人员外,还需依赖个体之间的责任关系传播,消除信息孤岛问题。社会网络(Social Network)中的个体之间存在复杂的责任关系,针对该问题,以滑坡事件发生时为例,创建带责任制的消息传播网模型,并采用微分进化算法评估关系属性和来往交流等因素对责任关系的影响权重,同时加入责任弱化(Responsibility Decline,RD)效应模拟消息传播过程。结果表明,关系属性和面对面交流对责任关系的影响较大,紧急消息的传播过程也会受距离的影响。实现了一对多的责任分派机制,多对多的责任分派方式则有待进一步研究。

Besides by the way of broadcast the information should he disseminated among individuals with responsibility for avoiding occurrence that someone dose not get informed while in a landslide. There exists complex relationship with responsibility with each other for which we constructed a model of network of information dissemination with accountability and evaluated, with Differential Evolution algorithm, different influence weights of emotional relationship, frequency of communications and other factors. Meanwhile,the RD was involved in the procedure of simulating information dissemination. Conclusions show that emotional relationship and face-to-face communication have greater effect on responsibility. Also the dissemination of emergency message is affected by the distances among people. The way of one-to-many to disseminate information comes out but the research for the way of many-to many is the next step.
