ROI Calculation Logic

Assuming a manufacturing site experiences 2,000 work interruptions annually due to screw detachment, each requiring 5 minutes for recovery. With 10 workers involved, each with an annual labor cost of ~$33.5K (AI est.), this technology could prevent ~1,800 interruptions by reducing detachment by 90%, potentially saving ~$50K (AI est.) in labor costs. Additionally, reducing the defect rate from 2% to 0.5% due to material damage prevention could save an estimated ~$5K (AI est.) in material costs annually. The total estimated economic impact is approximately ~$50K per year.
