1.Wave plan

Explanation of words: The wave plan is a way to improve the efficiency of the picking operation. It combines different orders into one wave according to a certain standard to guide one pick. More generally, the wave plan is to classify orders.The wave plan was created to improve order processing efficiency, balance the load of operations and the use of resources.

2. Relationship and difference between wave plan, picking strategy and picking method

The wave plan is to merge and classify bulk orders, so it contains the concept of "batch" processing. The wave plan can be a merger process based on the order, or it can be a combination of the goods in the order.
The picking method is a method of performing physical picking actions, and is divided into single picking and batch picking.
The picking strategy is the strategy when performing physical picking. There are many picking strategies, but the core elements that affect the picking strategy include four: partitioning, order splitting, order batching, and sorting. Different combinations of four factors produce different picking strategies.
Zoning: Division of the picking site. The wave plan management is most appropriate when the customer processes the majority of orders on the day, mainly at the beginning of each day. At the same time, the wave plan must have a classification standard as the basis for dividing the wave.

3. Wave segmentation optimization method for seeding sorting

Seeding sorting is a sorting operation in which one batch is aggregated for multiple orders. The batch of this job is often referred to as "waves" in the industry. (There is also a sort of “quasi-seeding” sorting method that sorts the goods while sorting. This article will not be discussed in this paper.) Using the seeding-type zero-distribution process, if the wave division is not appropriate, it will seriously affect the efficiency of sorting operations. It will also affect the overall service level of the distribution center.

In order to achieve higher work efficiency, seed sorting generally requires more orders to be aggregated per wave. However, for the following reasons, the number of orders aggregated per wave is never as good as possible:

1)Time limit for completing an order

2)Feasibility of cargo handling

3)Status of item overlap

4)Order size balance

5)Need for sorting

6)Delivery and transportation requirements

7)Processing capacity of sorting system equipment
