ROI Calculation Logic

Assuming a 1.5x increase in optical module product lifespan due to enhanced thermal stability. For a company shipping 100,000 units annually, this could reduce replacement part costs ($35/unit (AI est.)) and labor ($15/unit (AI est.)). The estimated reduction is (($35 + $15) * 100,000 units * (1 - 1/1.5)) = ~$1.5M (AI est.). Including yield improvement from higher precision, an annual cost reduction of ~$1.0M (AI est.) is expected.
