Simulation-based performance analysis of order picking systems

Abstract

Order picking is the process of retrieving items from the warehouse in response to a specific customer request. The design of an order picking system is often complicated and complex due to a large spectrum of external and internal factors, which influence the design choices. The most common objective of order picking systems during the design phase is to maximize the service level subject to reduce constraints such as labour, machines and capital. Therefore, the main objective of our paper is to present different policies for routing order pickers in one-block warehouse. Regarding the proposed routing policies, the effects on the order picking system performance will be presented.
