Sažetak
The efficiency of an order-picking operation both in manufacturing and distribution environment can be enhanced with AS/RSs, which can provide an alternative picker-to- parts solution for small objects picking from small racks where the products are stocked in cartons, totes, boxes or on trays. One of them is Vertical Lift Module (VLM) in which insertion/extraction (I/E) device is traveling vertically and extracts trays or totes from the shelves and brings them to the operator putting it on pick shelf. While usual VLM systems have only one picking place, recently some producers of VLMs offer solution with two pick places, naming it dual-tray VLM or dual-bay VLM. To design order-picking systems with dual-tray VLM, analytical throughput model is developed. However, model assumes pick time by human operator either deterministic or exponentially distributed. So in this paper different pick time distributions are analysed using simulations and compared with analytical solutions.
