Warehouse management is one of the many companies’ operations that is a main part of the supply chain. Storage takes up between 2 and 5% of the total cost of sales in an organization (Hwang and Cho (Comput Ind Eng 51(2):335–342, 2006)). The storage allocation of products is an activity inside the warehouses that help managing a good flow of the products. It is a complex issue since it depends on many parameters such as the number of spaces, the quantity of products, and the number of rack levels that are in the warehouse, and the resources to move, among other things. When optimizing the flow of operations in the warehouse, good decisions have to be made, and, in this work, through a systematic literature review, different academic papers published between 2005 and 2021 on the SLAP are analyzed and classified according to the solution methodology, objectives, and other characteristics, so that the most used methods in the literature are obtained for this type of problem as well as the parameters that are most taken into account to solve it.
