铁路物流中心功能区布局方法分析

为有效地解决铁路物流中心功能区的布局问题，在对布局规划理论与实践研究分析的基础上，将系统布置规划（SLP）方法用数学方法加以改进，建立以物流中心内各功能区间的综合相互关系函数，此函数是以最大和总成本最优为目标的函数。在一定的约束条件下，运用遗传算法求解。最后，将此方法进行实例验证，得到相对优化的布局方案，具有一定的参考意义。

Research on layout method for the functional area of railway logistics center

In order to solve the problem of the functional areas layout of railway logistic center effectively, on the basis of analyzing the situation of layout planning researches, it presents a mathematical method to improve the Systematic Layout Planning （SLP） method. Accordingly, under the definite constraints, the objective function is constructed with the maximum comprehensive relationship among the functional areas of logistics center and the minimum total cost. Genetic algorithm is used to work out the solution. Finally, the method is validated by an example to obtain the relatively optimal solution and to divide the area into several grids.
