Embodiment Construction

[0042] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0043] Such as figure 1 Shown is a work flow diagram of a method for generating a picking collection list of the present invention, including:

[0044] The sample acquisition step S101 is to acquire the location information of N orders, where N>1, the order is used as a sample, and the location information of the order is used as the sample two-dimensional coordinates of the corresponding sample, and the cluster number calculation step S102 is performed;

[0045] Cluster number calculation step S102, calculating the number of clusters included in the picking collection list c=N / d, where d is the preset number of samples included in each cluster, and the cluster is a set consisting of d samples , performing the clustering center initialization step S103;

[0046] Clustering center initialization step S103, select c samples from N sa...

Abstract

The invention relates to the correlation technical field of order picking operation, in particular to a method and device for generating order picking collection lists and a method for optimizing an order picking route. The generation method comprises the steps: obtaining position information of N order forms, using the order forms as samples, and using the position information of the order forms as sample two-dimensional coordinates of the corresponding samples, wherein N is greater than one; computing the number of clusters included by the order picking collection lists; selecting c samples from the N samples as initial samples; computing the distances between the sample two-dimensional coordinates of (N-c) samples except for the initial samples and c clustering centers, regarding the cluster where the clustering center with the shortest distance is located as a cluster to be classified, and returning the samples to the cluster to be classified; generating the corresponding order picking collection lists by the clusters if the iteration end condition is met, and continuing to perform iteration if the iteration end condition is not met. According to the order picking route generated by the optimized order picking collection lists, the order picking efficiency is improved greatly compared with the order picking efficiency in the prior art.

Description

technical field [0001] The invention relates to the technical field related to picking operations, in particular to a method and device for generating a picking collection list and a picking path optimization method. Background technique [0002] Today's WMS system (Warehouse Management System) has optimized the picking path to a certain extent, such as using genetic algorithm, ant colony algorithm, S-type heuristic algorithm, etc. to collect orders (a collection of orders to be picked, generally a The number of orders in the batch collection list is the same) for route optimization. When the path optimization algorithm is determined, how to determine the collection list to be optimized becomes an important step to further improve the efficiency of the picking operation. The selection of the collection list to be optimized directly affects the efficiency of the entire picking operation. [0003] The current common way to generate the collection order to be optimized is to i...
