Recently, order pickings for the deliveries are deemed to more important tasks in many facilities such as distribution centers. Furthermore, customers progressively require more diverse items, shorter lead time and more frequent deliveries. This trend constrains distribution centres from satisfying customers in an efficient way and encourages distribution centres to explore a new way for order picking. In this harsh environment, automation technology can be a good solution. This paper deals with a shuttle-based AS/RS and an automated picking workstations. A shuttle-based AS/RS is a new type of AS/RS in which multiple vehicles are used to retrieve and store items. An automated picking workstations help pickers to enhance their picking efficiency with automaton technology such as conveyors, auto identification, digital displays, etc. The object of this paper is to design a shuttle-based AS/RS and automated picking workstations. Comprehensive picking processes were designed to operate the picking and detailed functions of sub-systems that constitute the whole system were designed to realize the picking process. Computer simulations demonstrated that the proposed system operated well in an efficient way. This work is expected to be a practical guideline to the researchers who wants to build an automated miniload picking system.
