Abstract
The advantage of multimodal transport is that it can deliver the goods to their destination in a reasonable combination of transport modes while ensuring security and punctuality. Multimodal transportation can effectively reduce logistics costs, improve logistics efficiency, and reduce environmental pollution. In the process of multimodal transportation, due to the interference of natural factors (weather, terrain, etc.) and some special human factors, it may have different degrees of impact on the transportation time and transportation safety of different transportation modes. Therefore, when choosing a transportation method, it is necessary to consider the transportation time and transportation safety under the interference. However, the current research on multimodal transport has not considered the impact of external interference on transportation time and transportation safety. Compared with other modes of transportation, external interference has a relatively small impact on railway transportation. Railways can safely deliver goods to their destinations on time. Under the background of China’s huge railway network and advanced heavy-duty technology, this paper establishes a multimodal transport route selection model for considering railway as the core, introduces time penalty cost and damage compensation cost, and takes the lowest comprehensive transportation cost as the model objective under the premise of considering transportation reliability and transportation safety. Finally, taking a multimodal transport network in China as an example, an improved ant colony algorithm is used to solve the model and the results verify the rationality of the model.
Highlights
Multimodal transport [1] is a mode of cargo transportation through the connection and transshipment of two or more transportation modes to complete the transportation process
China is at an important stage of economic structural transformation and upgrading, and the freight transportation market is facing historical changes. e establishment of a new and efficient logistics channel based on multimodal transport can connect China’s inland economy and coastal economy, which is the key to the transformation and upgrading of
The scale of multimodal transport freight will account for 6% of the total freight volume%, the proportion is still low. e multimodal transport freight volume accounts for a small proportion of the whole society’s freight volume, which is caused by the Journal of Advanced Transportation incomplete construction of China’s current integrated transportation system
Summary
Multimodal transport [1] is a mode of cargo transportation through the connection and transshipment of two or more transportation modes (such as railway transportation, water transportation, road transportation, and air transportation) to complete the transportation process. Ere are some problems, such as imperfect mechanism, market segmentation, prominent transport structural contradictions, weak hub service capacity, poor operational coordination, and low safety and service level, which make the great potential of integrated transportation not fully released It affects the full play of the efficiency of various modes of transport and the public’s sense of gain (quoted: the 13th Five-Year Plan of Integrated Transport Services), which cannot meet the economic, reliable, and efficient freight demand. Erefore, this paper establishes a multimodal transport route selection model based on railway transportation, introduces time penalty cost and damage compensation cost, considering the transportation reliability and transportation safety factors in the transportation process, aiming at the minimum transportation cost, and finds the optimal path that is in line with reality
