AMR, AGV & Intralogistics Automation calculator
AGV Fleet Size Capacity Calculator
AGV fleet capacity is the number of material moves your automated guided vehicle fleet can actually complete in a shift after accounting for downtime and failed missions. Intralogistics engineers and automation planners use it to right-size fleets, validate vendor throughput claims, and decide whether to add vehicles before adding shifts. It matters because gross capacity on a spec sheet always overstates reality: chargers, blocked paths, and exception handling quietly erase a meaningful slice of every shift. This calculator derates the gross figure by availability and mission-success rate so you plan around moves you will truly get.
What this calculator does
- Estimate effective AGV move capacity from loads per route cycle, scheduled cycles, vehicle availability, and successful mission rate.
- an automation engineer needs to check whether planned AGV capacity covers required material moves
- It computes gross scheduled move capacity from loads per cycle and available cycles, then derates it by fleet availability and mission-success rate to give effective moves per shift.
Formula used
- Gross scheduled move capacity = loads moved per route cycle × available AGV route cycles
- Effective move capacity = gross capacity × AGV fleet availability × successful mission completion rate
Inputs explained
- Loads moved per AGV route cycle:
- Available AGV route cycles:
- AGV fleet availability:
- Successful mission completion rate:
How to use the result
- Use it when sizing an AGV or AMR fleet, validating a vendor's throughput guarantee, or checking whether current vehicles can absorb a demand increase.
- It uses shift-average availability and success rates; it does not model traffic congestion that worsens nonlinearly as you add vehicles to a shared path network.
Current U.S. benchmarks
- On-highway diesel averages $6.20 per gallon this week (EIA), trending up over recent periods. Truck tonnage is down 0.4% year over year (BTS via FRED).
Common questions
- How do you calculate effective AGV move capacity? Multiply loads per cycle by available cycles for gross capacity, then multiply by availability and mission-success rate. Here 2 x 420 = 840 gross moves, derated to 709.6 effective moves per shift.
- What is a realistic AGV fleet availability? Mature AGV fleets typically run 85-92% availability after charging, maintenance, and blockages. The 88% used here is a sound planning figure for an established installation.
- Why is effective capacity lower than gross capacity? Gross assumes every scheduled cycle completes a successful move. Availability strips out downtime (100.8 moves lost here) and mission-success strips out exceptions (29.6 moves lost), leaving 709.6 of the 840 gross moves.
- What is a good mission completion rate for AGVs? Well-tuned fleets exceed 95% mission success; the 96% here is typical once path conflicts and pick errors are under control. Lower rates point to layout or integration issues.
- How many AGVs do I need for a target move volume? Divide your required moves by per-vehicle effective capacity. Knowing one vehicle delivers about 709.6 effective moves per shift lets you scale the fleet to your demand directly.
- Gross vs effective AGV capacity - which should I plan with? Always plan with effective capacity. Committing to gross 840 moves when the fleet realistically delivers 709.6 leaves you roughly 130 moves short every shift.
