Abstract

The paper examines how the number of locations with the same item affects the average distance covered by the picker. The model proposed by Daniels, Rummel and Schantz [1998] allows to search the shortest route. Unfortunately the problem is NP-hard. The problem of selection the location with items to be picked is treated by Dmytrów [2015] in a different way: here the three criteria are evaluated. In the paper, the one-block rectangular warehouse with S-shape and return routing is analyzed. The average distance traveled in one picking tour is counted for different storage policies. The main finding is that increasing the number of locations not always leads to the improvement of the order-picking process. The calculations were performed using simulations.
