Randomness in RM Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization • Every problem in RM involves uncertainty. • Uncertainty means that a process is random. • Website visits • Conversions • Calls to reservations • Booking a room • Group sales • Restaurant visits • Check-in • No shows • Cancellations • We need to count how often we can expect a random event to occur. • How often an event occurs if the FREQUENCY.

Normal Distribution Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
Normal Distribution Excel 1 - NORM.DIST(number of rooms, average, standard deviation, TRUE) Given an average and a standard deviation, you can get the # of rooms that will be sold with a certain probability. NORM.INV(1-specific probability, average, standard deviation) Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization Given an average and a standard deviation, you can get the probability that any # of rooms will be sold.

Equation of a Line Y = SLOPE. X + INTERCEPT INTERCEPT SLOPE Rooms = SLOPE. Rate + INTERCEPT Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
The SLOPE Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
The SLOPE High Rooms Sold – Low Rooms Sold Slope = Low Rate – High Rate Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
Intercept Rooms = SLOPE. Rate + INTERCEPT Rooms - SLOPE. Rate = INTERCEPT Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
Demand Example 8 5 3 1 Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
Demand Formula Rooms = SLOPE. Rate + INTERCEPT (1,400) , (8,100) Rooms = -.023. Rate + 10.33 Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
Revenue Formula Rooms = SLOPE. Rate + INTERCEPT Revenue = Rate . Rooms Revenue = Rate . (SLOPE. Rate + INTERCEPT) Revenue = SLOPE. Rate2+ Rate.INTERCEPT Belmond RM Conference 2014 : Mathematical Hotel Revenue Optimization
