阐述科研合作网络弹性的概念、研究意义与应用,并以全球100所高校在图书情报学领域所组成的科研合作网络为例,选取网络最大簇规模和网络效率作为网络弹性测度指标,讨论节点点度失效、介数失效以及随机失效策略下该科研合作网络的弹性。结果显示,科研合作网络对随机节点失效具有较强的鲁棒性,其网络容错能力较强;对选择性节点失效的网络抗攻击能力较弱;网络效率相对于网络最大簇规模更适合作为科研合作网络弹性的测度指标。
This paper elaborates the concept, significance and application of the research cooperation network elasticity. Taking the research cooperation networks formed by 100 universities in the world of library and information science as an example, this paper selects the largest cluster size and network efficiency of the network as the index of network elasticity measure, Degree Failure, Incentive Failure and Stochastic Failure Strategy. The results show that the research cooperation network has strong robustness against stochastic node failure, strong network fault tolerance capability, weak attack resistance against selective node failure network, and network efficiency relative to the largest cluster size of network is more suitable for scientific research Cooperation Network resilience measure.
