AI Technical Summary

Technical Problem

Existing optimization methods have failed to effectively address the dual-yard layout for container allocation in rail-water intermodal transport, the two-way flow of imported and exported containers, and the transshipment and scheduling issues after container storage, resulting in low yard utilization and loading/unloading efficiency.

Method used

This paper proposes an optimization method for container space allocation and transshipment scheduling at ports and stations for rail-water intermodal transport. By acquiring relevant data, a general objective function is constructed. Combined with the idle status of port and railway yards, the transshipment routes of containers are dynamically planned, the transshipment process of containers in both directions is coordinated, and the allocation and transshipment scheduling of container spaces are optimized.

Benefits of technology

It has achieved joint optimization of container space allocation and transshipment scheduling, improved yard utilization and loading and unloading efficiency, reduced container waiting time and empty runs, and optimized the operational efficiency of rail-water intermodal transport.

Abstract

The invention provides a port station container space assignment and transfer scheduling optimization method for combined transportation of iron and water, and relates to the technical field of railway port station container space assignment and transfer optimization. According to the invention, by collecting related information of to-be-distributed containers, stockpiled containers in a storage yard, storage yard container positions and storage yard container transportation paths, a coupling optimization model taking container area operation container quantity balance and minimum container total transportation distance as objective functions is constructed; and collaboratively optimizing container space assignment plans and transfer plans of the containers in the port storage yard and the railway storage yard. According to the method, on the basis of comprehensively considering harbor-harbor station storage yard characteristics in the railway-iron combined transportation operation process, the container positions and the transfer plans are reasonably arranged, the railway-sea-sea-railway two-way container dynamic transition double-operation process is coordinated, and the stockpiling operation efficiency of harbor stations is improved.
