Order Picking Systems: A Queue Model for Dimensioning the Storage Capacity, the Crew of Pickers, and the AGV Fleet

Designing an order picking system can be very complex, as several interrelated control variables are involved. We address the sizing of storage capacity bay, crew pickers, and AGV fleet, which most important from a tactical viewpoint in parts-to-pickers system. Although is widely explored topic literature, no analytical model that simultaneously deal with these currently available. To bridge this gap, we introduce queue for Markovian processes, enables us to jointly optimise aforementioned variables. A discrete-event simulation then used validate our model, test proposal real data under different operative scenarios, aim assessing usefulness settings.
