Total vaccine supply: 150,000 doses Number of regions: 5 Equity floor: 40% of proportional share

⚠ Infeasible: the equity floor demands more doses than total supply can provide. Lower the floor or raise supply.

Bars show each region's optimal allocation (solid) against its full population (wire outline) and its equity-floor threshold (amber tick). The panel below the 3D view charts per-region coverage % against each region's own equity floor. Every number here comes from a real two-phase simplex solve recomputed the instant you move a slider — nothing is randomised or approximated.
