Investigating the robustness of aisles in a non-traditional unit-load warehouse design: Leverage

Abstract

Recently [9] proposed a non-traditional aisle design for unit-load warehouse for one centrally located pickup and deposit (PandD) point both on the lower and upper sides of warehouse. We call this design Leverage. However the number of PandD points is limited to one in design Leverage. Hence in this research we investigate the changes in improvement of Leverage as the number of PandD points increases by searching optimal designs by using [9]'s approach. We then compare Leverage with the improved designs to investigate its robustness in terms of changes in aisle structure and cost. © 2016 Elsevier B.V. All rights reserved.
