In order to meet the customers ’ demand quickly, warehousing industry develops fast, making more and more warehouses and distribution centers appear and operational efficiency more and more important. As an important part of warehouse management, order picking efficiency affects the operations of warehouse s and distribution center s deeply . And the storage location ina warehouse affects order picking efficiency. In this thesis , YB (Tianjin) Company warehouse is studied as the objective and the feasibility of slotting optimization is discussed . First, the paper makes a brief introduction of related theories on slotting optimization. Then, after warehouse introduction and analyzing current situation, the storage location is found unreasonable and needs tobe optimized. Next, under the class-based storage strategy, this paper proposes the minimum human energy expenditure caused by order picking as the optimization objective and determines the relevant constraints to build the optimization model, and ap
