ROI Calculation Logic

Glove port exchange in contaminated environments typically involves multiple specialists over several days, incurring high costs for personnel, specialized equipment, and waste disposal. Assuming a conventional exchange costs ~$6.5K (AI est.) for personnel, ~$3.5K (AI est.) for equipment downtime, and ~$3.5K (AI est.) for waste disposal, totaling ~$13.5K (AI est.) per exchange. This technology could reduce time and cost by 50%, saving ~$6.5K (AI est.) per exchange. For facilities performing 10 exchanges annually, this translates to ~$65K (AI est.) in direct cost savings, plus additional benefits from improved equipment uptime, totaling over ~$130K/year (AI est.) in economic impact.
