Robust Storage Assignment in Unit-Load Warehouses
Assigning products to and retrieving them from proper storage locations are crucial in minimizing the operating cost of a unit-load warehouse. The problem becomes intractable when the warehouse faces variable supply and uncertain demand in a multi-period setting. We assume a factor-based demand model in which demand for each product in each period is affinely dependent on some uncertain factors...
متن کاملAisle Configurations for Unit-Load Warehouses
Unit-load warehouses are used to store items—typically pallets—that can be stowed or retrieved in a single trip. In the traditional, ubiquitous design, storage racks are arranged to create parallel picking aisles, which force workers to travel rectilinear distances to picking locations. We consider the problem of arranging aisles in new ways to reduce the cost of travel within these warehouses....
متن کاملHow Energy Recovery Can Reshape Storage Assignment in Automated Warehouses
In automated storage and retrieval systems energy in descending and deceleration phases of cranes can be recovered into the power supply system instead of being dissipated as waste heat. Such technological opportunity should be exploited by properly modifying control policies in order to improve energy efficiency of warehousing operations. In this paper the impact of energy recovery on the stor...
متن کاملV. a Framework for the Robust Design of Unit Load Storage Systems
The unit load storage assignment problem determines the assignment of a set of unit loads with known arrival and departure times to a set of unit storage locations in a warehouse. The material handling device(s) can carry at most one unit load at the time. In this research it is assumed that each of the storage locations can be accessed directly without load relocations or rearrangements and th...
متن کاملTurnover-Based Storage in Non-Traditional Unit-Load Warehouse Designs
We investigate the effect of assigning the most-active items to the best locations in unitload warehouses with non-traditional aisles. Specifically, we report the performance of flying-V and fishbone designs when products exhibit different velocity profiles. We consider both singleand dual-command operations in a warehouse where receiving and shipping are located at the midpoint of one side of ...
