This article is that data of dispatch of 119 fire safety centers were analyzed using social network analysis and cluster analysis to improve the firefighting system following the transition to national jobs. First of all, through social network analysis, the relationship between 119 safety centers is analyzed. Fire departments with high Outdegree centrality suggested a relative allocation of human and material resources, and fire departments with high In-degree centrality suggested strategies for disaster prevention. Second, as a result of analyzing PAM (partitioning around medoids) clusters based on the relationship between Ambulance dispatches between 119 safety centers, new clusters (17, 9) were proposed. The proposed cluster was verified with data from Ambulance dispatch in 2018 and fire dispatch from 2015 to 2018. Based on this, a new cluster that is advantageous in terms of training, command, decision making, and communication was proposed.
Keywords : Clustering analysis, firefighting system, partitioning around medoids, social network analysis.
