[Abstract]:With the development of economy, the iron and steel logistics industry gradually highlights its advantages, the construction of modern steel logistics park is in full swing, and its scale is becoming larger and larger. At the same time, there are increasingly serious environmental problems within the park. Due to the unreasonable layout and planning, the waste of resources and the lack of connection, not only can not play an effective role in the scale of the park, but also cause a lot of environmental pollution. Therefore, it is of great practical significance to study the overall layout of iron and steel logistics park. Based on the analysis of the present development situation of China's iron and steel logistics park, this paper summarizes the existing problems in its development planning, and combines the relevant policies of implementing sustainable and low-carbon development in our country. The importance of scientific and reasonable layout of iron and steel logistics park is explained, and the basic process of overall layout planning of iron and steel logistics park is put forward. Then according to the economic situation and logistics demand of the region, combining the core correlation method and grey forecast method to forecast the demand of the steel logistics park, it provides reliable data support for the planning and design of the park. Avoid the phenomenon of blind construction and waste of resources. At the same time, the location of the park is accurate, the function area and scale are determined, the logistics flow is designed reasonably, and the repeated operation and transfer operation are reduced as much as possible, so as to realize the efficient operation of the park. Then, the paper analyzes the characteristics of the steel logistics park, and the transportation inside and outside the park, taking the special railway line and the entrance and exit as virtual function areas, and analyzing them together with other function areas. Considering the fixed constraints, entrance and exit constraints of special railway lines, as well as the requirements of the ratio of length and width of each functional area, the total cost of material handling in the park is minimized. The layout optimization model of the three optimization objectives of maximizing the comprehensive relationship between functional areas and maximizing the utilization rate of land area is proposed. The genetic algorithm is used to solve the problem and the layout scheme of the park is obtained. Finally, the scheme adjustment is carried out to form the overall layout of the park. Through the reasonable layout of the iron and steel logistics park, the traffic condition of the steel logistics park is improved fundamentally, the traffic congestion is reduced, the pollution is reduced, the operation efficiency of the park is improved, and the low carbonization and sustainable development of the operation of the park are ensured.
