Research on Route Optimization of Container Multimodal Transport Considering Capacity and Time Constraints

With the widespread use of multimodal container transport worldwide, traditional research on the need for more consideration of waiting time and penalty cost in the multimodal transport path optimization process. This paper focuses on the cost control and route selection of multimodal transport operators in the multitasking transport process, refines, and constructs an optimization model for the waiting time in the multitasking transport process based on comprehensive consideration of waiting for cost and penalty cost, studies the impact of nodal capacity and transport time in the transport network on various costs in the transport process, and conducts cost analysis through transport cases. The study shows that in multitasking transportation, full consideration of nodal capacity, transportation time, and changeover time can provide a more efficient reference for multimodal transport operators' transportation decisions, effectively reducing transportation costs, and improving the competitiveness of intermodal transport operators in the transportation market.
