发布时间:2018-07-28 07:53
【摘要】:物流园区功能区块的合理布局对于降低物流成本、提高物流作业效率有重要意义.传统的研究主要建立在假定物流园区是矩形的理想情况下,本文基于栅格数据结构,构建了以运输成本最小为目标的不规则物流园区功能区块布局的集合划分模型,并引入了栅格图像矢量化技术,用于提取布局形成后的图像拓扑结构,获得路网信息,然后设计了基于割树技术的变邻域搜索算法进行求解.最后以某物流园区为例,通过MATLAB编程计算得出布局方案,验证了本文模型和算法的有效性.
[Abstract]:The rational distribution of functional blocks in logistics parks is of great significance to reduce logistics costs and improve the efficiency of logistics operations. The traditional research is mainly based on the assumption that the logistics park is an ideal rectangle. Based on the raster data structure, this paper constructs a set partition model of the function block layout of the irregular logistics park with the minimum transportation cost as the goal. The raster image vectorization technique is introduced to extract the topological structure of the image and obtain the road network information. Then a variable neighborhood search algorithm based on cut tree technology is designed to solve the problem. Finally, taking a logistics park as an example, the layout scheme is calculated by MATLAB programming, which verifies the validity of the model and algorithm.
