基于复杂网络理论的氧化铝多效蒸发系统脆弱性评估研究

In term of complex networks, a novel method for analyzing the vulnerability of the structure of multi-effect alumina evaporation system is proposed. Based on complex network theory, the "components" and "connections" in the alumina evaporation system are described by nodes and edges of the network. Then a network model is developed and analyzed utilizing the topological structure characteristics. Moreover, according to different function of the system devices and the structure vulnerability theory of complex networks, the vulnerability of developed network nodes is investigated. A comprehensive vulnerability index is presented to find the vulnerable structure of the system. Finally, the computation of vulnerability index for multi-effect alumina evaporation system can be accomplished using simulation. Some vulnerability devices can be found and protected which insure the safety of the system. The method proposed in this paper may be used to identify the vulnerability of complex industry systems which can help to improve the operation status.
