SRIBD Seminar:Network Revenue Management Under a Spiked Multinomial Logit Choice Model
Speaker: Dr.Yufeng Cao   Topic: SRIBD Seminar:Network Revenue Management Under a Spiked Multinomial Logit Choice Model Abstract: Airline booking data have shown that the fraction of customers who choose the cheapest available fare class often is much greater than that predicted by the multinomial logit choice model calibrated with the data. For example, the fraction of customers who choose the cheapest available fare class is much greater than the fraction of customers who choose the next cheapest available one, even if the price difference is small. To model this spike in demand for the chea…
