Abstract
Recently, in the context of “The Belt and Road” Initiative, the China Railway Express, which has a high volume and spans a long distance has greatly facilitated the construction of international freight transport corridors between developed and developing countries. To ensure sustainable development, this paper introduces an optimization problem of a container distribution organization scheme for the China Railway Express resulting from the major existing problems arising in railway port stations, which is a special and crucial link in transportation organization of the China Railway Express. The problem of a long dwell time of inbound trains is typically concerned with the operation process in railway port stations. Taking various real-world influencing factors of efficiency into account, this paper formulates a distribution organization optimization model to minimize the total container-hours of inbound China Railway Express at Alataw Pass railway station. Subsequently, a solution method based on the main idea of a genetic algorithm is developed to solve the problem, and two examples of different modes of transportation organization are given for validating the effectiveness of the model. Finally, we compare the results between two modes under different orders of magnitude according to the characteristics of sustainability to discuss the possible change and development of the China Railway Express in the future.
Highlights
At present, accompanied with the support of the national programmatic document “Vision and Actions on Jointly Building Silk Road Economic Belt and 21st-Century Maritime Silk Road”, China Railway Express, which refers to the international container rail lines running between China and Europe, as well as countries along “The Belt and Road”, has maintained the momentum of rapid development.According to the requirement of construction planning, the east, middle and west corridors of the China Railway Express has been formed
The assembled transportation organization mode may only be applicable to the situation of a large number of inbound trains
We pay attention to the distribution organization optimization for inbound China Railway Express with equipment and transshipping time constraints in railway port stations, which may have an important impact on the high-volume and long-distance transportation organization and sustainable development of China Railway Express. We formulate this problem in view of the coordination of the operation process and facilities as a mathematical model which is leveraged to develop a genetic algorithm based on container allocation
Summary
At present, accompanied with the support of the national programmatic document “Vision and Actions on Jointly Building Silk Road Economic Belt and 21st-Century Maritime Silk Road”, China Railway Express, which refers to the international container rail lines running between China and Europe, as well as countries along “The Belt and Road”, has maintained the momentum of rapid development. According to the requirement of construction planning, the east, middle and west corridors of the China Railway Express has been formed. The west corridor (the red line in Figure 1), with the largest freight volume and highest benefit among the three corridors, mainly delivers goods from the central region of China towards Europe via the Alataw Pass railway station (a little through Khorgos). By the beginning of 2019, 59 cities in China had opened their China Railway Express lines, amounting. Of 19 2 of 21 ttoo aa ttoottaall ooff 6655 lliinneess.
