基于改进SLP方法的铁路物流中心布局规划研究

The Layout Planning of Railway Logistics Center Based on Improved SLP Method

铁路物流中心是铁路货运与外界连接的枢纽,其内部布局关系货物在其中运转的效率,对整个铁路货运的流畅性有着至关重要的影响。本文在对铁路物流中心功能分区的基础上,对功能区布局方法进行对比分析,提出基于改进SLP的功能区布局方法,以相互关系最大和总体搬运成本最小为优化目标,对几何和功能两方面进行约束,建立多目标优化模型,运用NSGA-Ⅱ进行求解,得到最优方案解集,最后运用AHP模糊综合评价方法进行评价对比,选出最优布局方案。并以S市铁路物流中心为案例,验证了方法的科学性和可行性。

The railway logistics center is the hub connecting the railway freight and the outside world.Its internal layout is related to the efficiency of the operation of goods in it,which has a crucial impact on the fluency of the entire railway freight.Based on the functional division of the railway logistics center,this paper compares and analyzes the layout method of the functional area,and proposes a functional area layout method based on improved SLP.Taking the maximum mutual relationship and the minimum overall transportation cost as the optimization goal,the two aspects of the function are constrained,the multi-objective optimization model is established,and the NSGA-Ⅱ is used to solve the problem,and the optimal solution set is obtained.Finally,the AHP fuzzy comprehensive evaluation method is used to compare and evaluate,and the optimal layout scheme is selected.Taking the S city railway logistics center as an example,the scientific and feasibility of the method are verified.
