Abstract

Optimization of transport capacity combinatorial procurement facing the actual carrier is an important decision that affects the operation efficiency and competitiveness of the non-vessel operating common carrier (NOVCC) type of sea-rail intermodal transport operator. Based on the hub-and-spoke network structure of container sea-rail intermodal transport, this paper conducts comprehensive consideration of sea-rail intermodal transport demand in various origin and destination (OD) markets, capacity limitations of shipping liners and regular railway trains, connections between space and time and so on from the perspective of multimodal transport operators (MTO). In order to minimize the total cost, the slots volume of procurement based on combinatorial selection in shipping liner and regular railway train is as the decision, an optimization model of transport capacity combinatorial procurement in container sea-rail intermodal transport is established, and an algorithm is designed for solving. The experimental results show that the model and algorithm are feasible, and achieve good application effect.
