高铁施工材料物流中心选址研究

摘要

In view of the practices of the supply of project materials in the construction of Beijing-Shanghai high-speed railway, taking steel rail as the study object, the paper analyzes its logistics mode, introduces the 0- 1 integer programming algorithm, and establishes the location model of transit stations. In the modeling process, the continuous material demand is treated approximately as the discrete demand of construction sites whose locations can be pinpointed and then the problem is solved using software MATLAB.%针对京沪线施工材料供应过程中的实际情况,以钢轨为例,分析其物流模式,引入了0-1整数规划,建立了中转站的选址模型.在建模时,考虑到了需求连续问题,用离散的可以确定位置的施工点的需求来近似连续需求,从而将连续需求问题离散化,最后用MATLAB软件对问题进行求解.
