Exact route-length formulas and a storage location assignment heuristic for picker-to-parts warehouses

Order picking is one of the most time-critical processes in warehouses. The authors focus on the combined effects of routing methods and storage location assignment on process performance. They present exact formulas for the average route length under any storage location assignment for four common routing methods. Properties of optimal solutions are derived that strongly reduce the solution space. Furthermore, the authors provide a dynamic programming approach that determines storage location assignments, using the route length formulas and optimality properties. Experiments underline the importance of the introduced procedures by revealing storage assignment patterns that have not been described in literature before.
