Case Study: SIJ Acroni achieves improved on-time delivery and shorter production cycles with DELMIA Quintiq

Sij Acroni Optimizes Specialty Steel Production With Delmia Quintiq

SIJ Acroni, part of Slovenia’s SIJ Group, is a leading producer of specialty flat-rolled steels (including stainless quarto plates, wear‑resistant and tool steels). Facing a high volume of small, customized orders and a diverse product mix, the company’s Excel-based planning struggled to provide end-to-end visibility, hampering delivery performance, asset utilization and inventory optimization.

SIJ Acroni deployed DELMIA Quintiq’s Company Planner in eight months to integrate planning across steelmaking, rolling and finishing, enable KPI-based decision‑making, and better manage bottlenecks, disruptions and maintenance. The change delivered a quick ROI with OTIF up 12.8%, production cycle time from booking to finished goods down 11.4% (booking to shipping down 15.4%), improved capacity use and greater planning flexibility, and the company plans to expand the partnership.
