Instrument capital is depreciated linearly. Annual depreciation = capital ÷ lifetime. Annual maintenance = capital × maintenance rate. These costs are shared identically by both scenarios.
FTE allocation is the fraction of one scientist's time and cost attributed to solubility operations — including plate setup, data review, and instrument oversight.
Annual capacity assumes continuous operation at peak throughput for the scheduled hours. Actual capacity may be lower due to plate loading, re-runs, and calibration.
ECHO fees apply per assay plate in the automated scenario and represent acoustic liquid handling service or consumable costs not present in the manual workflow.
Compound handling cost is common to both scenarios and represents any per-compound sample preparation performed upstream of the assay.
No re-run rate, reagent degradation, or downtime factors are included in this base model. These would increase costs for both scenarios proportionally.
