RT journal article T1 A Cost-Optimized Model for Dynamic Port Hinterland Delineation: An Application to the Spanish Port System A1 Martínez Torres, Manuel Francisco A1 Ruiz Águilar, Juan Jesús A1 Turias Domínguez, Ignacio José A1 Cerbán Jiménez, María del Mar A2 Ingeniería Industrial e Ingeniería Civil A2 Ingeniería Informática K1 port hinterland K1 logistics cost optimization K1 supply chain management K1 port competition K1 economic geography AB This study presents a methodology for determining port economic hinterlandsthrough comprehensive logistics optimization. The research advances traditional geographical approaches by developing an integrated cost model that considers maritime transport,inland transportation, warehousing expenses, and time-dependent factors. Testing thismethodology on the Spanish port system (with three main ports: Valencia, Algeciras, andBarcelona), we demonstrate how product characteristics and origins significantly influenceoptimal port selection and hinterland boundaries. The analysis examines both perishablegoods, using bananas and oranges as case studies, and non-perishable cargo from Asianand American origins. Results reveal distinct patterns of port influence depending on goodstype and origin. The study’s findings, visualized through innovative color-coded mapping,provide valuable insights for port authorities and logistics planners in optimizing supplychain decisions. Our approach contributes to port competition theory by establishing aquantitative framework for dynamic hinterland delineation based on actual logistics costsand operational factors.
