L1
Feasibility / Ethics / Legal
Safety, accessibility (ADA), non-discrimination, guaranteed bookings. These are inviolable — no revenue or operational objective can override them.
Key Constraints & Formulas
VIP guarantee
\sum_{r} y_{b^{\text{VIP}},r,d} = 1 \quad \forall d \in D_{b^{\text{VIP}}}
(L1.1)ADA access
\sum_{r \in R^{\text{ADA}}} y_{b^{\text{ADA}},r,d} = 1 \quad \forall d \in D_{b^{\text{ADA}}}
(L1.2)Room exclusivity
\sum_{b} y_{b,r,d} \leq 1 \quad \forall r, \forall d
(L1.3)Same-room continuity
y_{b,r,d} = y_{b,r,d+1} \quad \forall (b,r,d) \in \text{ContPair}
(L1.4)Paper Example
A VIP guest is always guaranteed a room assignment — even if rejecting them would boost revenue.
