ABSTRACT
Distribution centers of E-commerce companies have been under pressure as a result of the development of the Internet and E-commerce technologies. Therefore, the improvement of order picking efficiency and the reduction of logistics cost rely on the optimization of order picking in distribution centers. In this paper, a picker-robot collaboration order picking system has been proposed. The human pickers are assigned to different zones, while the automated guided vehicles (AGVs) pick the orders from different zones. To optimize the collaboration scheme, the mathematical model together with a two-stage heuristic algorithm is proposed to solve the problems, including order batching, AGV routing and zone scheduling. The case study results have shown the effectiveness and the computation efficiency of the proposed two-stage heuristic algorithm.

A study of storage assignment problem for an order picking line in a pick-and-pass warehousing system
Order picking is one of the most crucial factors for efficient warehouse management. Most of previous research in order picking in a warehouse considered only the picker-to-part or part-to-picker system; however, the pick-and-pass system plays an ...
Storage assignment problem with travel distance and blocking considerations for a picker-to-part order picking system
Order picking is a key operation in managing a warehouse efficiently. Most previous studies on picking only considered single-picker operation; however, many pickers frequently work concurrently in the same region. Since congestion may occur in such a ...
