Nyrstar, a global zinc and lead producer, faced rising complexity after expanding from Europe into North America and Australia. The company replaced its spreadsheet-based planning system with DELMIA Quintiq to manage multi-period optimization, material blending, site-specific constraints, and volatile metal prices. The solution integrated with SAP and enabled faster scenario planning, improved data visibility, and better coordination between commercial and operations teams.

Key takeaways

Multi-period optimization replaced single-year spreadsheet models to handle variable production mixes and feedback loops

Blending optimizer determines optimal raw material mix, purchase quantities, and treatment locations across sites

SAP integration created a single source of truth and improved inbound supply chain visibility

Scenario run time dropped from two days to a few hours, supporting rapid response to supply disruptions

Planner time allocation shifted from 30 percent planning to 80 percent planning after implementation
