Work out agv fleet size instantly with clear inputs, formula shown and shareable results.
Fleet size is demand divided by the throughput of one vehicle, where that throughput is 60 divided by the cycle time in minutes, reduced by availability and inflated by congestion. Congestion is the term most often forgotten, and it grows non-linearly as the fleet fills the available routes.
AGV fleet
vehicle rate = 60 / (cycle x (1 + traffic loss)) x availability; fleet = ceil(demand / vehicle rate)
Vehicles block each other at intersections and single-lane sections, so waiting time rises sharply once route utilisation passes roughly 60%.
Round up, then consider one additional vehicle for maintenance cover if the process cannot tolerate reduced throughput.
