A schedule generated by mathematical programming was enthusiastically adopted for the 2020 season and significantly outperformed previous manually produced schedules.","PeriodicalId":430990,"journal":{"name":"INFORMS J.

Products in P&G’s 10-category portfolio of products are sold in over 180 countries. The Consumer Research Analytics group at P&G empowers internal clients by using analytics to ensure that the products in P&G’s portfolio of products are not just well received by consumers but become the products of choice for the maximum number of consumers, thereby maximizing P&G’s market share. One of the most frequently used analytical approaches for managing a product line is Total Unduplicated Reach and Frequency analysis. We replaced the previous enumerative approach with integer programming coupled with cuts to the unit hypercube to dramatically speed up the analysis. As a result, P&G achieved higher utilization of its system, improvements to existing products, and more thorough analyses for product line planning and other applications.","PeriodicalId":430990,"journal":{"name":"INFORMS J.

Anderson","doi":"10.1287/inte.2021.1075","DOIUrl":"https://doi.org/10.1287/inte.2021.1075","url":null,"abstract":"In this paper, we propose a new dynamic pricing approach for the vacation rental revenue management problem. The proposed approach is based on a conditional logistic regression that predicts the purchasing probability for rental units as a function of various factors, such as lead time, availability, property features, and market selling prices. In order to estimate the price sensitivity throughout the booking horizon, a rolling window technique is provided to smooth the impact over time and build a consistent estimation. We apply a nonlinear optimization algorithm to determine optimal prices to maximize the revenue, considering current demand, availability from both the rental company and its competitors, and the price sensitivity of the rental guest. A booking curve heuristic is used to align the booking pace with business targets and feed the adjustments back into the optimization routine. We illustrate the proposed approach by successfully applying it to the revenue management problem of Wyndham Destinations vacation rentals. Model performance is evaluated by pricing two regions within the Wyndham network for part of the 2018 vacation season, indicating revenue per unit growth of 3.5% and 5.2% (for the two regions) through model use.","PeriodicalId":430990,"journal":{"name":"INFORMS J.
