Abstract: This paper adopts network analysis to investigate the feasibility of recruiting nearby fishing vessels as the initial rescue force for search-and-rescue operations. Network analysis was conducted to analyze the proximity among fishing vessels according to the type of fishing. The results were used as input to an adjacency matrix and schematized by applying the network. Given that fish species tend to travel together, fishing vessels in pursuit of them also operate in the same waters, essentially forming a network. It is thus desirable to secure a search-and-rescue system among fishing vessels of the same fishing type for prompt rescue. Specifically, network analysis confirmed that fishing vessels of the same type within 10 nautical miles can become vigilant, and a system of prompt rescue support can thus be secured; this approach improves the overall speed of rescue operations. These findings can be used as baseline data for developing a practical search-and-rescue system through a network of fishing vessels of the same fishing type.
