Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of high-speed rail freight transportation, and particularly relates to a high-speed rail freight data information management system and a scheduling management method thereof. BACKGROUND

[0002] With the rapid development of global economic integration and e-commerce, the logistics industry is undergoing unprecedented changes. In particular, in the field of railway freight transportation, traditional freight transportation methods have gradually failed to meet the needs of modern logistics for high efficiency, high reliability, and full tracking.

[0003] According to the market research results of the transportation organization modes adopted on the three freight train test lines of Beijing-Wuhan, Zhengzhou-Chongqing, and Chengdu-Kunming, the full advantages of the freight trains have not been fully utilized. In particular, due to the current use of pure manual loading and unloading methods on the three lines, the loading and unloading efficiency is relatively low. Therefore, in order to meet such loading and unloading needs, the three lines can only adopt an end-to-end transportation organization mode for the opening of freight trains, and cannot realize full-load transportation through the setting of intermediate stops according to the transportation needs of the freight sources. Such a transportation organization mode, due to the lack of necessary flexibility, cannot meet the needs of the market and customers, and the transportation efficiency and benefits cannot be optimized, resulting in the common problem of the three test lines being the difficulty in organizing freight sources, which cannot meet the transportation capacity needs of the regularly operated freight trains.

[0004] Railway freight transportation, especially high-speed rail freight transportation, has become an important part of the modern logistics system due to its large capacity, low cost, and environmental advantages. However, high-speed rail freight transportation still faces many challenges and limitations in actual operation.

[0005] 1) Relatively lagging logistics informatization construction

[0006] From the current construction of railway logistics information systems, due to the dispersion and difference of the freight transportation operation subjects and the fact that they are not affiliated with each other, various types of logistics information systems exist independently and are distributed in parallel, and a unified railway logistics information platform has not been formed, resulting in the inability to realize integrated railway logistics transportation data. At the same time, due to the relatively closed nature of railway logistics information systems, they cannot be fully compatible with external social information systems, and therefore cannot realize the sharing of logistics information and the tracking of the entire process of logistics information.

[0007] 2) Poor multimodal transport connection capability

[0008] In view of the actual situation of railway logistics in terms of business model, infrastructure, information system, business process, and operation standard at the present stage, railway logistics transportation is difficult to seamlessly connect with other transportation modes. The construction of logistics parks, sea ports, and "the last mile" is slightly lagging behind, and the cost of short barge transportation is relatively high, which will have certain influence and restriction on the development of intermodal transportation between sea, water, and road and railway.

[0009] 3) Lack of capacity of transport resource scheduling integration

[0010] In recent years, although railway transportation has achieved relatively considerable results in the release of existing line capacity, it is still facing problems such as lack of loading and unloading capacity of freight stations and insufficient capacity of marshalling stations. Due to the imperfect logistics function of freight stations, especially the serious lack of the level of transport equipment containerization and mechanization, and the distance between individual railway freight stations and local freight distribution centers is far, there is a problem of logistics island.

[0011] 4) Transport organization efficiency needs to be improved

[0012] Due to the lack of organization and management capacity in each link of transportation, there are generally situations such as delayed loading and unloading, late trains or delayed distribution, which will inevitably affect the time limit for transporting goods. At the same time, in the practice of railway transportation organization and management, in order to further improve the efficiency of transportation organization, it is also necessary to pay attention to the continuous optimization of the dispatching command system.

[0013] 5) Railway transport capacity does not adapt to market demand

[0014] When designing railway transportation products, the railway department usually starts from the transportation organization of the railway, and rarely designs transportation products in combination with the needs of customers, especially the needs of personalized and customized product services. Therefore, there are few time-limited express products, containerized transportation products and full-process logistics service products in the railway transportation products that adapt to market and customer demand, which to some extent restricts the competitiveness of railway in the freight market.
