By Alex Ibarra, Research Analyst — Planning, Order Management & Point of Sale · Supply Chain Research
Case study showing how SIJ Acroni replaced Excel planning with DELMIA Quintiq to manage complex specialty steel orders and improve delivery performance.
SIJ Acroni, a Slovenian producer of stainless and specialty steel plates, implemented DELMIA Quintiq Company Planner to replace manual Excel-based scheduling. The solution provides end-to-end visibility across steelmaking, rolling, and finishing processes, enabling optimized resource use, bottleneck identification, and KPI-driven decision making. Results included double-digit gains in on-time delivery and reduced production cycle times within eight months of go-live.
Replaced Excel planning with integrated APS for high-mix, low-volume steel production
Gained full material flow visibility from furnace through cutting and packaging
Improved OTIF delivery by 11.4 percent and shortened production cycles
Enabled KPI-based planning to balance delivery, cycle time, and inventory targets
Implemented in eight months with internal team trained for ongoing maintenance
