Hyundai Saves $540K Annually with Optimized Production Scheduling
Paint Shop Color Changes and Welding Constraints Were Costing Hundreds of Thousands Annually
Hyundai faced two critical operational bottlenecks: inefficient welding shop scheduling requiring management of multiple operational constraints, and excessive paint shop material consumption due to frequent color changes necessitating extensive robot flushing. The objective was to improve production sequencing and reduce material consumption while maintaining manufacturing flexibility across a plant producing 1,400 vehicles daily.
AI Scheduler Accounts for 14 Production Constraints and Groups Vehicles by Color Automatically
Working with Adastra, Hyundai developed an optimization model accounting for up to 14 critical production constraints. The system sequences vehicle models on the assembly line while ensuring balanced distribution — limiting identical models to five consecutive units — and minimizing paint robot flushes. A 22-day testing phase validated the approach before full deployment.
$540K Saved per Year with ROI Achieved in Three Months
The optimized scheduling system delivers $540,000 in annual savings with a return on investment achieved in just three months. Planners now complete scheduling in under five minutes. Paint primer grouping improved by 74% (consecutive same-color vehicles), and topcoat efficiency improved by 54%.
"The grouping of cars by colour improved by an average of 74% for primer and 54% for topcoat applications."Artur Heider, Production Planning Specialist, Hyundai Motor Manufacturing Czech
