摘要：

According to the business process of railway logistics center and the relationship between each business, the logistics center is divided into 12 functional areas according to three categories of functions, namely, basic function, value-added function and auxiliary function. By quantitatively analyzing the influencing factors of the functional area layout, mathematical method is used to improve Systematic Layout Planning (SLP) method. With the improved SLP, and based on the close degree of the logistics and non-logistics relationships among each functional area in logistics center, the comprehensive relationship table of functional area is set up. Accordingly, under the following constraints, such as, railway loading and unloading line in fixed position, each functional area layout not overlapping, each functional area may not exceed the boundary of planned area in the logistics center, the logistics center gateway can only be at the boundary of the planned area in the logistics center and so on, the objective function is constructed with the minimum total handling cost and the maximum comprehensive relationship. Then the optimal single objective function of the functional area layout is got by the normalized processing. Genetic algorithm is used to work out the solution, and a scientific and reasonable layout scheme for functional area is obtained. Example has validated that the method is reasonable and effective.
