Research on Logistics Center Location Problem Based on p-Median Model

摘要: 针对物流中心选址问题，分析和比较了几种常用的选址方法和求解算法。建立了用于求解物流中心选址问题的p-中值模型，利用贪婪取走启发式算法(Greedy Dropping Heuristic Algorithm)，实现了模型的快速求解。结合具体案例，编写了算法对应的程序，解决了一类实际的选址问题，验证了模型的正确性和算法的可行性。

Abstract: For logistics center location problem, this paper analyzed and compared several commonly used location methods and algorithms. The p-median model for solving the logistics center location problem is established and the fast solution of the model is realized by using Greedy Dropping Heuristic Algorithm. Combined with specific cases, a kind of actual location problem is solved to verify the correctness of the model and the feasibility of the algorithm by writing the program corresponding to the algorithm.
