Algo Price Dynamic

Phase 1: Input Validation

Collect: current demand indicators, remaining inventory/capacity, time until expiration/event, competitor prices, price floor/ceiling constraints. Gate: Real-time data feeds connected, business rules defined.

Phase 2: Core Algorithm

Rule-based: If demand > threshold, increase price by X%. Tiered rules by inventory level.

Demand-curve based: 1. Estimate demand curve at current conditions. 2. Find price that maximizes revenue = P × Q(P). 3. Apply inventory constraint: if capacity is scarce, price up; if excess, price down.

ML-based: Train model to predict demand at each price point given context features. Optimize over predicted demand curve.

Phase 3: Verification

Monitor: revenue per unit, booking pace, customer complaints, competitive position. A/B test new pricing rules. Gate: Revenue improved without significant volume loss or customer backlash.

Phase 4: Output

Return recommended price with reasoning and expected impact.

}

Examples

Sample I/O

Input: Hotel room, 3 days until date, 85% occupancy, average competitor price $150 Expected: Price above competitor ($160-170) due to high occupancy, short time horizon.

Edge Cases

Gotchas

• Customer fairness perception: Visible price discrimination (same product, different prices for different users) generates backlash. Segment by time, channel, or bundle — not by individual.
• Price war spiraling: Automated competitive pricing can create a race to the bottom. Set absolute floors and rate-of-change limits.
• Demand cannibalization: If customers learn prices drop later, they wait. This is the "strategic customer" problem — don't train customers to delay.
• Regulatory risk: Dynamic pricing may violate anti-gouging laws during emergencies. Build in legal constraint rules.
• A/B testing bias: Testing different prices creates revenue measurement challenges. The control group at the "wrong" price loses money by design.
