ROI Calculation Logic

The introduction of this technology is projected to generate an annual economic impact of ~$0.7M (AI est.). This is based on reducing lost profit from operational delays (e.g., ~$6.5K/day (AI est.) × 50 days/year = ~$350K/year (AI est.)) and mitigating accident risk from human error (e.g., ~$350K/incident (AI est.) × 1 incident/year = ~$350K/year (AI est.)), with an assumed 20% reduction in each category's impact. This figure excludes planning effort reduction and focuses on overall operational optimization.
