Journal of Data Processing Guannan Si, Guang Yang, Hairong Xiao 6 4 2016 http://www.dline.info/jdp/fulltext/v6n4/jdpv6n4_2.pdf An abstract model of the logical relationship among the alarm and algorithm based on hierarchical priority alarm correlation inference rules are proposed by analysis of existing alarm correlation needs. The algorithm clearly describes the relationship and alarm, and can be flexibly combined multi-part configured to expand coverage area of the algorithm rules. It is in favor of knowledge update in change process of the network structure.
