Resumen
This paper deals with intermodal operations optimization methods to be implemented by the Block Train Operator upon cargo flows asymmetries at the hinterland. The algorithm of containerized cargo flows analysis and mathematical model were developed based on the relevant intermodal operation system.Inland leg of inbound containers from seaport to customer door arranged by truck is dominating within the emerging markets environment. Also imbalance in in- and outbound container flows as far as volumes, container size and payload is the case for largest inland destinations. Hence, the issue of rail-road transport prioritization and operational manageability is becoming of utmost importance. Centralizing those operations under a holistic service company ? block train operator has been proven feasible.Last mile deliveries prioritization approach is offered to achieve the highest number of inbound containers processing with their further utilization for outbound export shipments. Mathematical modeling was conducted for distinct sets of operational scenarios that might take place. The scenario that allows the block train operator to achieve the highest revenue numbers and emptied inbound containers utilization for exports was selected. The number of truck heads, chassis and truck driver mitigation has become a secondary objective. The optimal scenario selected helps to reduce the overheads risk at the time of weekly cargo volumes fluctuations.The optimization approach represented can be applied to intermodal operations within markets where volume imbalance is rather possible
