【摘要】：伴随着现代科学技术的发展,仓储物流也越来越被人们所关注。而自动化立体仓库(以下统称立体仓库)得到了更加广泛的应用,在医药配送中心中也开始投入使用。应用立体仓库可以实现整个物流系统的自动化和信息化,立体仓库的调度作业优化决定了仓储部门的作业效率,也对整个物流系统的运行起着关键作用。目前,虽然有一些关于立体仓库调度作业优化的研究,但是在入库货位优化和出库调度作业上的堆垛机路径选择的问题仍然不是很清晰。本文从以下几个方面进行研究:首先,分析了国内外学者对运行作业优化问题的研究成果,根据现阶段的不足,提出本文的研究论点。再对立体仓库基本构成和分类进行简述分析,分析立体仓库存在的优势和劣势,提出了一套完整的设计原则。其次,对立体仓库的入库货位优化进行研究分析。通过货位优化改善货物的入库的作业效率,提高立体仓库布局的合理性,减少成本投入,降低工作人员与机械设备的工作强度和时间。然后以某医药配送中心为例,通过遗传算法进行入库货位优化研究分析。最后,分析立体仓库的出库调度作业研究。分析出库时候的拣选作业,选定拣选方式。分析出库调度的基本原则,然后以巷道堆垛机行走时间和路线最短为目标,建立出库作业调度优化的数学模型,利用蚁群算法的基本原理和计算步骤,对某医药配送中心的出库作业进行优化研究。通过对立体仓库的运行优化研究,可以加快货物的存取速度,降低劳动强度,提高整个仓储部门的作业效率。
[Abstract]:With the development of modern science and technology, warehouse logistics has been paid more and more attention. Automated warehouse (hereinafter referred to as stereoscopic warehouse) has been more widely used in medical distribution center. The application of stereoscopic warehouse can realize the automation and information of the whole logistics system. The optimization of the scheduling of the warehouse determines the operation efficiency of the storage department and plays a key role in the operation of the whole logistics system. At present, although there are some researches on scheduling job optimization of stereoscopic warehouse, the problem of stacker path selection in storage location optimization and outbound scheduling is still not clear. This paper studies from the following aspects: first of all, it analyzes the research results of domestic and foreign scholars on the operation optimization problem, according to the shortcomings of the present stage, puts forward the research point of this paper. The basic structure and classification of stereoscopic warehouse are analyzed briefly, the advantages and disadvantages of stereoscopic warehouse are analyzed, and a set of complete design principles are put forward. Secondly, the optimization of the storage location of the three-dimensional warehouse is studied and analyzed. Through the optimization of cargo location, the operation efficiency of goods entering warehouse is improved, the rationality of the layout of three-dimensional warehouse is improved, the cost input is reduced, and the working intensity and time of staff and mechanical equipment are reduced. Then taking a medical distribution center as an example, the genetic algorithm is used to analyze the optimal storage location. Finally, the research on the scheduling of the warehouse is analyzed. Analyze the picking operation when out of the library, and select the picking method. Based on the analysis of the basic principles of outbound scheduling, aiming at the shortest running time and route of the stacker crane, the mathematical model of scheduling optimization is established, and the basic principle and calculation steps of ant colony algorithm are used. This paper studies the optimization of the outbound operation of a medical distribution center. By optimizing the operation of the warehouse, it can speed up the storage and storage of goods, reduce the labor intensity and improve the working efficiency of the whole warehouse department.
