The purpose of this project was to investigate if an improvement of the time consumed to move goods in a specific grocery warehouse can be made by changing and adding factors to the current allocation model. After analyzing raw data collected from the warehouse and constructing new models, the factors of interest could be evaluated. Evaluation of the factors was made by simulations and statistical testing. Factors that were investigated were the turnover for the different articles and an ABC classification made on that factor. Changes in articles saturation for the aisles were also considered. The findings may give some useful insights of paths for further investigation and future improvement of the logistic system of the warehouse.
