Order processing and shelf assignment method for intelligent warehouse

Abstract

The invention discloses an order processing and shelf assignment method for an intelligent warehouse, being characterized in that an order aggregation strategy and a shelf assignment strategy are combined; the optimality of each strategy and the coupling of the two strategies are comprehensively considered; a reasonable and rapid scheduling scheme is made for the sorting operation of the intelligent warehouse, so that the limitation of a single strategy is broken through, and the efficiency for sorting operation is effectively improved; and under the actual storage environment condition, underthe conditions that the number of orders is large, and the types of goods are wide, and the size of shelves in the warehouse is large and the number of goods stored in the shelves is limited, the orders are reasonably aggregated, and the shelves are reasonably distributed, thus guaranteeing that the number of times that the shelves enter a station is as small as possible, and the sorting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent warehouses, and in particular relates to an order processing and shelf assignment method for intelligent warehouses. Background technique [0002] With the vigorous development of China's logistics industry, the number of user orders is increasing rapidly, and the types of orders are diversified. This has led to the increasing volume of self-built warehouses in the field of warehousing and logistics, and the types and quantities of goods stored in warehouses are increasing day by day. In this complex and ever-changing scenario, the traditional manual picking of goods in the order is no longer applicable, and smart warehouse sorting is becoming more and more popular. At present, a common way of intelligent picking of goods is to set up multiple order picking stations in the warehouse picking area, and use the warehouse handling robot to move the shelves containing the goods to the designated p...

Problems solved by technology

[0003] In related existing technologies, some methods consider the above two strategies separately. For example, orders are only aggregated according to the order of arrival time, and shelves are assigned based on the principle of proximity. Due to the coupling of strategies, it will actually lead to lower picking efficiency. and huge time cost

Although the other method considers the two strategies together, it needs to add additional constraints, such as limiting the moving area of ​​the shelf, or assuming that the shelf stores an infinite number of goods, etc., which makes it difficult to apply in actual production.
