AI production system at LG Smart Park in Changwon

LG's refrigerator plant forecasts its line 10 minutes ahead and reports 20% higher productivity

WorkingCompany's own claimOfficial ↗

Problem

The Changwon refrigerator plant builds many models for Korea, the US and Europe on shared lines. Mixing models on one line makes it harder to deliver the right parts on time and to react to equipment problems.

Approach

LG Electronics developed its own production system that combines AI, big data and a digital twin of the factory. It collects and analyses plant data every 30 seconds, forecasts the state of the line 10 minutes ahead and schedules material supply accordingly. Overhead conveyors and automated guided vehicles move parts and doors. The World Economic Forum named the site a lighthouse factory in March 2022, the first Korean home-appliance plant to be selected.
