# Case studies: what changes when the decision becomes optimized > Success stories from Orion's applications, with gains measured in operation, in increasing order of complexity: from a problem that fits on one machine to one that reorganizes a manufacturing network across three countries. Clients are always anonymous. Sectors: Logistics and transportation, Manufacturing, Metalworking, Strategic planning. ## Cutting optimization cut raw-material waste by 80% - Sector: Metalworking - Client: Metal processing manufacturer - Results: 80% reduction in raw-material waste; 100 coil types considered in the model; 80 cutting patterns optimized together One hundred coil types, eighty cutting patterns and projected inventory are now solved together, instead of decided one cut at a time.
