A U-shaped layout for manual order-picking systems
In manual order picking systems, order pickers walk or ride through a warehouse in order to collect items requested by customers. The performance of such a system is significantly dependent on its layout which determines the lengths of the order pickers’ tours and the corresponding picking times. Whereas for classic warehouse layouts all picking aisles are arranged in parallel to each other, in...
متن کاملContinuous-Time Models for Estimating Picker Blocking in Order-Picking-Systems
Congestion is a problem in order-picking-systems. We developed CTMC models to represent picker blocking in cases including pickers with different exponentially distributed picking times and k pickers, for narrow and wide aisle systems. The focus was not to produce an all-inclusive model, but to generate models that give designers insight of the system, allowing them to reduce the number of vari...
متن کاملTabu search heuristics for the order batching problem in manual order picking systems
In manual order picking systems, order pickers walk or ride through a distribution warehouse in order to collect items requested by (internal or external) customers. In order to perform these operations efficiently, it is usually required that customer orders are combined into (more substantial) picking orders of limited size. The Order Batching Problem considered in this paper deals with the q...

متن کاملMetaheuristics for order batching and sequencing in manual order picking systems
Order picking deals with the retrieval of articles from their storage locations in order to satisfy customer requests. A major issue in manual order picking systems concerns of the transformation and consolidation of customer orders into picking orders (order batching). In practice, customer orders have to be completed by certain due dates in order to avoid delay in the shipment to customers or...
