Sorting method, system, equipment and medium

Abstract

The invention provides a sorting method, system and device and a medium, and the method comprises the steps: planning a target sorting path based on a preset target sorting model according to a target sorting task and target storage information; wherein the target sorting model is established based on the fact that a target with an early warehousing batch is firstly delivered out of a warehouse and the walking distance of a sorting target is shortest under the relaxation condition that the target number selected by each goods allocation does not exceed the target total number of the goods allocation, and the constraint condition that each target is selected from one goods allocation is met; and target sorting is carried out according to the planned target sorting path. The targets are sorted through the preset target sorting model, the targets with the early in-out warehouse batch can be preferentially sorted, and it is guaranteed that the targets are consumed as early as possible to reduce the inventory cost; and moreover, the walking route with the shortest walking distance from the sorting equipment to the sorting target can be planned, and the sorting efficiency is improved.

Description

technical field [0001] The invention relates to the field of automation, in particular to a sorting method, system, equipment and medium. Background technique [0002] With the gradual increase of the running density of EMUs in my country, the task of EMU target selection is heavy and the time is tight. Because the objects required for object selection are not only of various types, but also of a large number. Leading to Object Selection The selection of objects is a very complex task. [0003] Multiple factors need to be considered in the selection of target picking targets. First, the batch objects that are put into storage are consumed first. This sorting method can consume the earliest inventory, avoiding the expiration of some parts caused by the backlog of inventory, and reducing the cost of EMU target picking; It is the shortest travel distance of the picking equipment to improve the picking efficiency. [0004] The existing picking plan usually adopts the method o...
