—Visual Analysis & Methodology
Computational Logic — v2.5Capacity = (cobotArcEffective / manualArc) × Number of Shifts
Op.FTE = (opRatio / 100) × ShiftNumber
Net Savings = Manual Cost - Operation Cost - Maintenance
Payback = CAPEX / NetSavings × 12 (months)
ROI = (Net Savings × Year − CAPEX) / CAPEX × 100★ Depreciation is not included in cash flow; it is for accounting purposes only.
