Planning refers to management decisions that affect the intermediate term (one or multiple months), such as inventory management and storage location assignment. Control refers to the operational decisions that the short term (hours, day), such as routing, sequencing, scheduling and orderbatching. Prior to the literature survey, we give an introduction into warehousing systems and a classification of warehouse management problems. 1. Introduction . The increasingly busy warehouse Gudehus [1] and Graves [2], Hausman [3] and Schwarz [4] introduced the design, planning and control of ware housing systems as new research topics. The operation of warehousing systems has received considerable interest in the literature ever since. It is not surprising that the research on warehousing systems gained interest in the 1970s, since this was the era that management interest shifted from productivity im provement to inventory reduction. The introduction of information systems made this strategy possible, with Manufacturing Resources Planning (MRPII) as a notable example. From Japan a new management philosophy emerged: JustInTime (JIT) production. JIT attempts to achieve highvolume production using minimal inven tories of parts that arrive just in time. These new devel opments demanded from warehouses that low volumes be delivered more frequently with shorter response times from a significantly wider variety of Stock Keeping Units (SKU39。s). The new interest in quality forced warehouse managers to reexamine their warehouse operation from the viewpoint of minimizing product damage, establish ing short and reliable transaction times and improving orderpicking accuracy. Current trends in warehousing and distribution logis tics are supply chain management and E?cient Consumer Response (ECR). Supply chain management and ECR pursue a demanddriven anization of the supply chain with small inventories and reliable short response times throughout the supply chain. All deliveries are driven by the sales downward in the supply chain. Such an anization requires a close cooperation among the panies in the supply chain and the immediate feedback of sales data. Nowadays, information technology enables these developments through Electronic Data Interchange (EDI) and software systems such as the MRPbased Enterprise Resources Planning (ERP) systems and Warehouse Management Systems (WMS). The new market forces have the operation of warehouses tremendously. On the one hand,
