Your Equipment Got Smarter — So Why Is Lead Time Unchanged?
Many plants replace CNC machines and roll out an MES, only to find delivery lead times exactly where they were. Dig into the numbers and the answer is usually the same: actual machining accounts for only 5–10% of manufacturing lead time; the rest is transport, waiting, and queuing. The processes got smarter, but intralogistics — the movement *between* processes — still runs on forklifts, hand carts, and people walking.
That is why inquiries about AMRs (Autonomous Mobile Robots) surged across Korean plants in 2026. A shrinking working-age population makes it hard to staff simple material handling, and high-mix, low-volume production means frequent line changes that expose the limits of fixed automation.
AGV vs. AMR: The Decisive Difference
Three Numbers You Must Calculate Before Deployment
1) Measure actual transport volume
Sizing a fleet by intuition is always wrong. Spend at least two weeks measuring `daily trips × round-trip distance × minutes per trip`. If you run 120 trips a day at an average 160 m round trip and 4 minutes each, that is 8 hours a day spent purely on moving things. At roughly ₩20,000 per hour fully loaded, that is about ₩40 million a year over 250 operating days, or ₩48 million over 300. With a single AMR costing ₩60–100 million, payback lands in the 1.5–2.5 year range depending on operating days.
2) Physical constraint checklist
Aisle width (cart width plus at least 300 mm clearance per side), floor flatness, thresholds, gratings and ramps, interlocks with fire shutters and automatic doors, elevator I/O integration if the route crosses floors, and Wi-Fi roaming dead zones. A single 3 cm threshold discovered after installation can stall an entire project.
3) MES/WMS integration design
This is the most common cause of failure. Without a structure that tells the robot *what* to move, *when*, and *where*, operators end up dispatching every task by hand on a tablet — that is a tool swap, not automation. Make the interface that pushes MES work orders and process-completion events into the fleet manager's task queue an explicit part of project scope.

Leveraging Government Support Programs
How KITIM Can Help
The Korea Institute of Technology Innovation Management (KITIM) supports the full path from intralogistics diagnosis to program selection. We handle AMR fleet sizing based on on-site transport measurement and traffic analysis, feasibility review reflecting aisle, floor, and interlock conditions, MES/WMS integration scoping, and proposal writing and evaluation support built around quantitative KPIs. If you want to confirm whether the investment truly pays back in *your* plant before you commit capital, request a consultation through the KITIM inquiry page. Starting with an on-site diagnosis is the fastest route.
