| Popis: | 94 This paper considers the problem of constructing order batches for distribution centers using a clustering analysis. Order picking is one of the most important key factors for an efficient warehouse management. Most of previous research in order picking considered only single-picker operation; however, there are often multiple pickers concurrently working at the same region in a real distribution center. Since congestion may occur in such a multiple picker system, waiting time must be taken into account together with travel time or travel distance in the evaluation of the efficiency for the picking operations. Order picking is routine in distribution centers. Before picking a large set of orders, effectively grouping orders into batches can accelerate product movement with the storage zone. The literature has proposed a order batching and processing heuristic to address aisle congestion for minimizing travel distance or travel time. The purpose of this research is to study the effect of congestion on the order picking operations in a multiple picker distribution center with a parallel-aisle layout. This paper compares the total travel time for different order batching algorithm. A simulation model is proposed and developed to implement these various heuristic. The results show that the proposed order batching heuristic outperform the existing traditional order batching algorithm in a multiple picker warehouse environment. |
