Problems solved by technology

[0004] Some researchers have proposed a solution based on the reinforcement learning theory in the field of artificial intelligence for the classic box packing problem, but the actual improvement of the effect is also very limited.
In addition, the box packing problem actually applied in the field of logistics packaging is different

Example Embodiment

[0021] The present invention will be described in detail below in conjunction with the drawings. However, it should be understood that the drawings are only provided for a better understanding of the present invention, and they should not be construed as limiting the present invention.

[0022] The method for generating a packing plan for items in a logistics warehouse provided by the present invention includes the following steps:

[0023] 1) Obtain multi-angle images of all items in the order, and use digital image processing methods to obtain three-dimensional size data of all items in the order and store them in the database according to the obtained multi-angle images.

[0024] Several cameras can be used to take multi-angle images of items or infrared scanning and other methods to obtain multi-angle images of items, and the three-dimensional data of the length, width and height of the product can be obtained through the method of multi-view reconstruction three-dimensional mode...

Abstract

The invention relates to a method and system for generating a boxing scheme of articles in a logistics warehouse, and the method is characterized in that the method comprises the following steps: 1) obtaining the three-dimensional size data of all types of boxes and all articles in an order; 2) adopting a heuristic search algorithm and a genetic algorithm, according to the three-dimensional size data of all types of boxes and all articles in the order and set proficiency degree parameters, for a specific box selection scheme, searching to obtain the minimum height of the box required for loading all articles in the order under each box selection scheme and all boxing schemes meeting the minimum height of the box; and 3) searching to obtain an optimal boxing scheme required by the order according to the minimum height of the box under each box selection scheme and all boxing schemes thereof, and preset starting conditions and cut-off conditions, so that the method can be widely appliedto the fields of space planning technologies and application systems.

Description

technical field [0001] The invention relates to a method and a system for generating a packing scheme for items in a logistics warehouse, and belongs to the field of space planning technology and application systems. Background technique [0002] In the modern logistics industry, a large number of orders are submitted to the logistics storage center every day. Warehouse workers are required to take out the goods according to the orders, pack them into cartons of appropriate size, and send them to customers everywhere. Due to the boom in global e-commerce, these orders are huge, especially in China. However, due to the high speed required for logistics packaging and the uneven proficiency of workers, fewer items are packed in oversized boxes in many cases, resulting in serious waste of paper and logistics and transportation resources. [0003] Researchers have conducted in-depth research on the classic bin packing problem, and proposed solutions such as mathematical optimiza...
