The COVID-19 pandemic has significantly increased logistics demand, necessitating efficient urban logistics infrastructure. In response, the Korean government plans to utilize vacant spaces within Seoul’s subway vehicle bases and develop large-scale logistics complexes in strategic locations. This study focuses on site selection for urban logistics centers within the Seoul Metropolitan Subway area using Analytical Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methodologies. Key criteria for site selection are categorized into facility, geographical, environmental, and social factors. AHP results indicate geographical factors are most significant, followed by facility, social, and environmental factors. TOPSIS rankings show Sinnae as the most suitable site, followed by Godeok and Cheonwang. Recommendations include strategic infrastructure investment, fostering cooperation between logistics companies and local governments, integrating advanced technologies, implementing green logistics, workforce development, and community engagement. Limitations include reliance on current data and the need for future research incorporating updated data, environmental sustainability, and social equity.
