Global supply chains are increasingly exposed to maritime chokepoints, geopolitical disruption, border friction and sustainability pressure. This paper reframes the emerging Saudi–Türkiye rail and logistics corridor as a supply chain resilience capability rather than a conventional transport infrastructure project. The study addresses a gap in the literature: supply chain resilience research has largely emphasized firm-level practices such as inventory buffers, supplier diversification and operational recovery, while the resilience role of logistics corridors remains underexplored. A Monte Carlo simulation and scenario-analysis framework is developed to compare four route-inventory alternatives between Saudi Arabia and Türkiye: the Jeddah–Suez–Mersin maritime route, the Dammam–Hormuz–Suez–Mersin maritime sensitivity route, the Saudi–Jordan–Syria–Türkiye rail corridor and the Iraq–Türkiye multimodal corridor. The model evaluates total logistics cost, lead time, reliability, disruption exposure, carbon emissions and a composite Corridor Resilience Index. Open-source route data and freight benchmarks are used to calibrate the maritime inputs, while non-operational rail and multimodal corridor segments are treated as scenario assumptions. The paper contributes by conceptualizing corridor diversification as a supply chain resilience capability, developing a multi-criteria simulation framework and translating route performance into managerial decision rules for resilient logistics planning.
