Decision Matrix — Infusion Pump Tender Evaluation

A most-economically-advantageous-tender evaluation for volumetric infusion pumps in four weighted groups (safety 35%, usability 25%, interoperability 20%, price 20%), scored 0–10 with programming steps and five-year cost measured. Bidder Y has the highest total at 7.62 but fails the dose-error-reduction must-have, so Bidder X ranks first at 7.09 of 10, 0.19 ahead of Bidder Z. Illustrative values.
