| 摘 要： | 针对现有的基于相连链路联系的故障研究方法不能准确描述Cyber空间因资源发生故障而造成的影响这个问题,提出了一种从共享任务联系的角度分析资源故障传播与扩散问题的研究方法。其基本思想是利用Petri网建模方法描述Cyber空间中任务与资源的基本关系,基于超图理论构建任务-资源模型。定义了传播能力、传播系数、扩散系数等指标来刻画故障的传播与扩散过程,采用邻接矩阵分析并推导出了这些指标的量化方法,在此基础上给出了资源故障在网络中产生的影响力的函数,最后利用案例验证了资源的故障传播和扩散过程。

| Abstract: | Due to inaccurate evaluation of the impact on Cyberspace resource failure caused by the current link-based methods for failure spreading,a mission based method was proposed to analyze failure spreading and diffusion in Cyberspace.This article analyzed basic relations between missions and resources by utilizing the Petri net methodology,and built a task/resource model based on the hypergraph theory.This model defines concepts of spreading ability,spreading coefficient,diffusion coefficient and fault influence,which can be conducted and quantified by adjacent matrix.On this basis,the influence function of resource failure was derived.Finally,we tested process of failure spreading and diffusion in a case study. |
