This case study evaluated the storage management of a consumer goods warehouse, in which the cycle time to prepare an order was high (from 2 to 8 hours depending on the order type). The warehouse presented some inconveniences such as: long time to perform operations and great mobilization of people and products. Consequently, this study aims to: 1) reduce the order picking times and 2) reduce picking costs. The methodology used divided the study in two phases: current situation analysis and improvement proposal. During the first phase some lean tools were used to identify the main cause of the problem. Then, to develop the improvement proposal, a mathematical model was designed to present a new – more appropriate – configuration of the existing SKU’s within the warehouse considering type products constraints and ABC classification. Results shows an adequate configuration of the picking area, decrease of personnel mobilization, reduction of picking times and reduction of operative cost associated with picking.
