基于入侵杂草算法的WMS货位优化分配的研究

近年来,仓储管理的发展越来越迅速,在物流业中所居的地位也越来越高。仓库的出入库速度是影响仓库效率的重要因素,因此合理的库位分配可以有效地提高仓库的作业效率。针对仓库货位分配策略问题,以相同产品存储相邻位置、提高产品出入库效率、提高货架稳定性为目标,建立了多目标优化模型;然后使用权重系数法将多目标优化模型转化为单目标优化模型;最后分别通过遗传算法和入侵杂草算法来求解该单目标优化模型,并使用Matlab软件进行了仿真实验。对比两种算法的仿真结果可以看出,采用入侵杂草算法可以有效地解决自动化立体仓库的货位优化分配问题。

Agricultural Market Name Geo-Locating System Based on an Administrative Ontology and Web Search Engine

The problem of associating the agricultural market names on web sites with their locations is essential for geographical analysis of the agricultural products. In this paper, an algorithm which employs the administrative ontology and the statistics from the search results were proposed. The experiments with 100 market names collected from web sites were conducted. The experimental results demonstrate that the algorithm proposed obtains satisfactory performance in resolving the problem above, thus the effectiveness of the method is verified.
