“…They developed a simulation model for SKU assignment based on the EIQ strategy and demonstrated that their approach facilitated improvements. A number of studies focused on cigarette picking systems utilizing two kinds of dispensing machines (He et al , 2007; Liu et al , 2008, 2009; Zhang and Wu, 2007). Wu and Zhang (2008) designed a method to sequence orders to increase the efficiency of their cigarette dispensing system.…”

Purpose This paper aims to explore methods of defining ejecting zones (EZs) used in automatic picking systems (APSs), particularly in A-frame APSs. An A-frame APS automatically ejects products onto a conveyor, which then brings the products to their destination. EZs are moving zones on a conveyor, and each EZ corresponds to one picking order. Products are ejected as a zone passes channels in which the products are stored. Design/methodology/approach First, three EZ types are defined, and their operations are explained. Second, picking orders are analyzed and categorized by considering the structure and the picking mechanism of an A-frame APS. In addition, picking-order instances reflecting actual data are randomly generated according to each category. Finally, the performance of the EZs is evaluated using the picking-order instances and computer simulations. Findings The results from the computer simulations suggest the EZ types suitable for use with various picking order types considering order fulfilment speed and energy usage. Research limitations/implications In this paper, the authors only adopt a triangular distribution which is considered most practical distribution in the industry. Practical implications It is believed that these results can provide managers and operators with useful guides to facilitate the effective operation of an A-frame APS. The provided ideas have been implemented at the pharmaceutical warehouse of the largest logistics company in Korea. Social implications The result shows that the proposed idea could save energy consumption and the APS have potential to save labor involvement in picking. Originality/value It is essential to define the EZs when operating an A-frame APS efficiently, but there is almost no research in this area. This paper focuses on defining EZs, as well as methods to utilize these zones.

“…For sorting operation modes, traditional manual mode has the disadvantages of low efficiency and high error rate [4]. Modern modes such as automated sorting machine and stereoscopic warehouse, which mainly depend on transmission equipment and logistics information technology, have the advantage of higher sorting efficiency, but also have some shortages such as large area occupied, poor flexibility and robustness, etc [5][6][7].…”

With the rapid development of express industry, traditional sorting operation mode has been unable to meet customers' requirements for speed. As modern automatic logistics equipment, Automated Guided Vehicle (AGV) has many advantages. It can not only reduce the number of operators and greatly improve the working productivity, but also has the characters of flexibility and reliability. In this paper, an AGV system used in express sorting operation is built. Then its business process, system architecture and task schedule algorithm are specified. Finally, AGV sorting system is developed using C# and simulation experiments are carried out. The efficiency and error rate of AGV sorting system is compared with traditional sorting methods. Simulation results show that it can be more effective and stable to use the AGV system in logistics sorting operation.
