摘　　要：微分法是一种常用的求解一元网点布局建模问题的方法,以总成本最低为目标,精确求解某一区域内物流设施位置坐标。其计算过程较繁杂,运用计算机软件能起到辅助的作用。研究使用Excel和Lingo两种计算机软件求解物流设施位置坐标,实现微分法求解选址问题。结果表明,使用上述两种软件可以有效获得最优解。其中,又以Lingo软件计算过程更为快捷、逻辑更为清晰。Differential method is commonly-used to solve the modeling problem of unitary dot layout,aiming at minimizing total cost and accurately solving the location coordinates of logistics facilities in a certain area.Its calculation process is more complicated,with the use of computer software playing an auxiliary role.In this paper,Excel and Lingo are used to solve the location coordinates of logistics facilities so as to work out the location problem by Differential method.The results show that the optimal solution can be obtained effectively by using the above two kinds of software.Meanwhile,Lingo software is more efficient and logical in the calculation process.
