## manual
zara don't like doing markdown, but the first season = clearance
absolute value similar, elasciticy jump
velocity, price = 0
max revenue (constraint: inventory you have; discounts you're giving, )
inventory is nothing to get rid of
infinite inventory, hurts inventory
scare inventory, start competing -> when we start competing
what are decision variables? how long i keep the price at 100, 90, 80...
constraints are limited inventory (<=2000) and time (total time <=16)
given i set the price, limited
p(sell rate) * x_H, p(sell rate) * x_L
max p(sell rate) * x_H * $/unit, p(sell rate) * x_L * $/unit
🚿rinse and repeat

## Learning Objectives
- Understand revenue management principles and applications
- Analyze dynamic pricing strategies and their effectiveness
- Apply capacity allocation and overbooking models
- Evaluate revenue optimization vs. customer satisfaction trade-offs
## Key Concepts
### Revenue Management Fundamentals
- **Definition:** The application of disciplined analytics to predict customer behavior and optimize product availability and price to maximize revenue growth
- **Core Principle:** Sell the right product to the right customer at the right time for the right price
- **Prerequisites:** Perishable inventory, heterogeneous customers, advance booking capability
### Industry Applications
#### Airlines
- **Perishable Inventory:** Seats on specific flights
- **Price Discrimination:** Business vs. leisure travelers
- **Booking Patterns:** Advance purchase vs. last-minute
- **Capacity Constraints:** Fixed number of seats per flight
#### Hotels
- **Perishable Inventory:** Room-nights
- **Demand Patterns:** Business vs. leisure, seasonal variations
- **Length of Stay:** Different value segments
- **Ancillary Revenue:** Food, beverage, services
#### Other Industries
- **Rental Cars:** Fleet utilization optimization
- **Cruise Lines:** Cabin category management
- **Theaters/Sports:** Event ticket pricing
- **Restaurants:** Peak time pricing
- **Ride-sharing:** Surge pricing (Uber/Lyft)
### Customer Segmentation
#### Willingness to Pay
- **Business Travelers:** High willingness to pay, low price sensitivity
- **Leisure Travelers:** Lower willingness to pay, high price sensitivity
- **Price-Sensitive:** Budget-conscious customers
- **Convenience-Focused:** Value time over money
#### Booking Behavior
- **Early Bookers:** Plan ahead, price-sensitive
- **Late Bookers:** Less flexible, higher willingness to pay
- **Group Bookings:** Different pricing dynamics
- **Frequent Customers:** Loyalty program considerations
### Demand Patterns
#### Time-Based Variation
- **Advance Booking Curve:** How demand evolves over time
- **Seasonal Patterns:** Predictable demand cycles
- **Day-of-Week Effects:** Business vs. leisure patterns
- **Time-of-Day Variations:** Peak vs. off-peak periods
#### Price Sensitivity
- **Elasticity:** Demand response to price changes
- **Reference Pricing:** Customer expectations based on past prices
- **Competitor Pricing:** Market positioning considerations
- **Value Perception:** Quality-price relationship
## Revenue Management Models
### Single-Resource Models
#### Static Pricing
- **Newsvendor Extension:** Optimal capacity given fixed price
- **Price Optimization:** Find price that maximizes expected revenue
- **Demand Function:** Relationship between price and demand
- **Mathematical Formulation:** max p·E[min(D(p), C)]
#### Dynamic Pricing
- **Price Evolution:** How prices change over booking period
- **Information Updates:** Adjust prices based on observed demand
- **Optimal Control:** Dynamic programming approaches
- **Real-Time Optimization:** Continuous price adjustment
### Capacity Allocation Models
#### Two-Class Problem
- **High-Fare Class:** Limited inventory, higher revenue
- **Low-Fare Class:** Remaining capacity, lower revenue
- **Booking Limit:** Maximum low-fare reservations to accept
- **Protection Level:** Capacity reserved for high-fare class
#### Multi-Class Extensions
- **Fare Class Hierarchy:** Multiple price points
- **Nested Booking Limits:** Cumulative availability controls
- **Bid Price Models:** Opportunity cost pricing
- **Network Revenue Management:** Multi-leg optimization
### Overbooking Models
#### No-Show Problem
- **Customer Behavior:** Some confirmed customers don't arrive
- **Revenue Loss:** Empty capacity due to no-shows
- **Service Risk:** Denied boarding if everyone shows up
- **Optimization:** Balance revenue gain vs. service cost
#### Overbooking Decision
- **Costs:** Denied boarding compensation and customer dissatisfaction
- **Benefits:** Revenue from additional bookings
- **Probability Model:** No-show and demand distributions
- **Optimal Level:** Minimize expected total cost
## Implementation Strategies
### Demand Forecasting
- **Historical Data:** Past booking and consumption patterns
- **Market Intelligence:** Competitor pricing and capacity
- **External Factors:** Events, weather, economic conditions
- **Machine Learning:** Advanced predictive models
### Price Optimization
- **A/B Testing:** Experiment with different pricing strategies
- **Competitive Monitoring:** Track competitor prices and availability
- **Demand Sensing:** Real-time demand signal detection
- **Price Elasticity:** Measure customer response to price changes
### Technology Systems

- **Distribution Channels:** Online, travel agents, direct sales
- **Real-Time Updates:** Dynamic pricing and availability
- **Performance Monitoring:** KPI tracking and reporting
## Strategic Considerations

## Mathematical Framework
### Basic Revenue Function
- **Revenue = Price × Quantity Sold**
- **R(p) = p × min(D(p), C)**
- Where D(p) is demand function and C is capacity
### Optimal Pricing

- **With Capacity Constraint:** Consider opportunity cost of capacity
- **Dynamic Setting:** Future revenue implications of current decisions
### Capacity Allocation
- **Expected Marginal Revenue:** EMR of last unit in each class
- **Optimal Allocation:** Equalize EMR across classes
- **Protection Levels:** Reserve capacity for higher-value segments
