Abstract
Order picking is the most labor-intensive and costly activity for almost every warehouse. The problem of order picking routing in a warehouse is mainly solved using heuristics. The objective of this paper is investigating the impact of order picking regions on the performance of four order-picking routing heuristics. A proposed warehouse is divided to twelve main regions and large numbers of randomly test problems are generated. The computational results show that the order region has significance impact on the performance of the routing heuristics.
