Optimization Research on Site Selection and Layout of Fire Stations in Traditional Villages Based on Fire Safety Urgency
Traditional village architectural clusters in contiguous development are often located in remote moun-tainous areas with insufficient firefighting and rescue facilities.The current layout of fire stations is inadequate to meet the demands of firefighting and rescue operations,leading to the potential for extensive fire spread and los-ses.To address this issue,a method for optimizing the site selection and layout of fire stations based on fire safety urgency is proposed.Considering the spatial characteristics of fire spread risks in different architectural clusters and existing firefighting coverage indicators,the fire safety urgency for various architectural clusters is deter-mined.A combination of set covering models and maximum coverage models is employed to optimize the current layout of fire stations with low and medium safety urgency as optimization objectives.The effectiveness of the method is validated using traditional villages in Lijiang City as an example.The results indicate significant differ-ences in fire safety urgency among different architectural clusters,with 31.48％classified as extremely high or high safety urgency and only 16.67％as low safety urgency.By using the proposed method,it is only necessary to add 15 small fire stations to satisfy all architectural clusters in a low to medium safety urgency state,with approxi-mately 81.48％of the clusters having low safety urgency.
