| dc.description.abstract | Online shopping is a new type of consumption. Its advantages are that it is not limited by time and place, and can be consumed at any time. Due to the above reasons, consumption patterns have gradually shifted from physical stores to e-commerce platforms in recent years. Changes in shopping patterns also test the production capacity and efficiency of the entire logistics system. In addition, in order to satisfy and attract consumers, e-commerce platforms have come up with many methods in recent years, such as timely delivery within 24 hours or 6 hours to attract customers. Because of this, In addition to the capacity and efficiency of the logistics center, rapid response to consumer demand is also a must for the logistics center.
The Locusbots system is a new type of picking system using dynamic path planning, which can quickly update environmental information and find feasible paths, effectively avoid obstacles, and make the system routes smoother; It can also be expanded and contracted at any time. In addition, one person is responsible for one picking area, which can reduce the contact between picking personnel in the working environment; personnel do not need to move around in the warehouse, only responsible for their own area is enough; the personnel only need to be familiar with their own picking area; it can reduce the manpower required by the traditional logistics center.
In the ＂Locusbots system＂, the picking process can be considered in three parts. The first part is to assign orders to AGV, so that the AGV can enter the logistics center for picking; the second part is to dispatching AGV. The AGV goes to the picking area to pick the items ; the third part is about when AGV arrives, which AGV should be selected into the picking area .
This research mainly discusses the ＂Locusbots system＂, with ＂Selecting AGV in the picking area＂, ＂order selection＂ and ＂dispatching rules＂. It is hoped that through complete simulation experiments and performance analysis, the understanding of such problems will be increased, and similar research will be made in the future. | en_US |
