A Slicing Tree Based For The Logistics Park Layout

In recent years, with the rapid growth of China’s national economy, the material flows between the regions are becoming more frequent, the logistics park provides a strong support for the material exchange between the regional major cities. Logistics Park as a carrier of logistics functions, the effective realization of its functions depends on a reasonable layout of the functional areas of logistics parks. A well-designed logistics park will not only improve the utilization of facilities, the goods turnover rate, but also to strengthen its ability to radiate around the park to the logistics activities. Therefore, how to set and layout the functional areas of the logistics park is a worthwhile study.After analyzing and summarizing the research in the field of facilities layout, we build a layout optimization model of Logistics Park based on cut tree structure and genetic algorithm. At the same time, we try to put some influencing factors, such as the existing transportation facilities and fixed facilities to optimize model. Then, we use C++programming to solve the optimization model and output the layout graphical. Finally, we verify the effectiveness and practicality of the optimization model by PT Logistics Park.The results of our study show that:we can put some harsh constraints and people’s experience into the model of logistics park layout to make the results of the layout is more realistic and scientific. The software prepared in this paper not only has a strong operational, but also can output a Satisfactory reference solution.In addition, depending on the relative location of the various functional areas, the Dijkstra algorithm we proposed to calculate the distance of various functional areas for the shape is rectangular or approximately rectangular logistics park is more realistic than the straight-line distance between the center points of the functional areas.
