Order sorting method and system

Abstract

The embodiment of the invention provides order sorting method and system. The method comprises the steps of: generating a storehouse plane layout according to the putting condition of storehouse shelves; then computing the shortest path between nodes in a storehouse; finding out the positions, sizes and the weight of goods required for an order from pre-stored data; computing the shortest path and distance between any two pieces of required goods by using the shortest path between the nodes; and computing the optimal sorting path according to the capacity of sorting equipment and the required quantity of the required goods in the order so as to sort orders by the sorting equipment according to the optimal sorting path. The embodiment of the invention can effectively compute the sorting path, reduce the working cost, enhance the working efficiency, and solve the problems of inconsistent shelf arrangement, relatively small shelf height, and small expense difference caused by storing and taking the goods on different layers of shelves of the same goods position; and sorting workers mainly need to optimize order sorting problem in the horizontal movement distance for sorting work.

Description

technical field [0001] The invention relates to the field of warehouse picking operations in logistics warehousing, in particular to an order picking method and system that needs to move horizontally in multiple lanes. Background technique [0002] Warehouse picking operation is the core of modern logistics distribution, and the level of modernization of logistics distribution depends on the picking technology. Many large warehouses or distribution centers use high-rise shelf-type three-dimensional warehouses. There is an aisle between two adjacent rows of shelves, and each aisle has a stacker. The stacker can move along the vertical and horizontal directions at the same time. Goods on side vertical shelves. Such as figure 1 As shown, point 0 is the entrance and exit of the roadway, and a, b, c, d, e, f are several pick-up points on the vertical shelf. The stacker can pick up the goods on several positions at a time, and then return to point 0 Place the case on the convey...

AI Technical Summary

Problems solved by technology

In this type of enterprise, the batch size of the order is small, and there are many types of goods involved in the order, which needs to be picked in a wider range. In this type of warehouse, the height of the shelves is not high, and many picking operations are carried out manually. Personnel can easily remove the goods in the upper shelf, so the working distance in the vertical direction is negligible, and the above method cannot solve this problem
