新华书店的区域配送中心选址模型

The Location Model of the Xinhua Bookstore's Region Logistics Distribution Center

文章针对省新华书店配送中心选址问题,综合考虑了书籍运输成本与区域配送中心运营成本等成本因素。建立了以区域配送中心总成本最小化为目标的一个混合整数选址模型;在模型求解方法的选择上,根据混合整数模型的特点,提出了将模型的求解分成两个部分:线性部分采用运输规划法求解,非线性部分采用隐枚举法求解;最后通过实例论证了模型对求解配送中心选址问题的可行性并得到了比较满意的选址结果。

This paper, addressing itself to the location-selection for the New China Bookstore of province distribution center, fully considers cost factors such as books transportation cost and region distribution center operation cost. Taking the region distribution center total cost minimum as a goal, the paper has established a mix-integer location-selection model for distribution center. In the model solution method＇s choice, according to the mix integer model＇s characteristic, the paper proposed to divide the model solution into two parts. The linear segment used the transportation plan method to solve and the misalignment part used the implicit enumeration to solve. Finally the paper proved the model＇s feasibility through the example to solve the location-selection for the distribution center and obtained the quite satisfactory the location-selection result.
