Calculation method
Calculation method
Net whole mL to purchase
max(0,sum supplied process mL+reserve−available stock).
Minimum-cash pack counts under stated volume-only model
Exact bounded integer-volume dynamic programming, minimizing US cents then excess volume, then pack count for each exact volume.
Purchased volume (mL)
Sum selected pack quantities×pack volume.
Purchase volume above stated net need (mL)
Purchased volume−net requirement, not an inferred process dose.
Modeled pack cash total ($)
Sum supplied pack prices; compatible fluid/product choice is external.

Assumptions & limits
Assumptions & limits
- A supplied-volume compatible-pack purchase model, not a fluid specification, bleeding procedure or service-quantity recommendation. Compatibility and process quantities must already be approved externally; no purchase is made.
