The travel alert manager generates an alert for the alert data type based on a primary alert condition, the alert to provide a notification that the travel data will affect a travel property. The travel alert manager determines a priority of the alert and issues the alert if alerts matching the priority of the alert are authorized by system settings."Share this quote In March, the patent office received an application from Duetto that's similarly intriguing. The patent describes... "a profit optimization module identifies historical transaction data associated with a travel property. The historical transaction data includes bookings made for a same day of the week as the day of arrival during a forecast period for a plurality of previous weeks. The profit optimization module also identifies lost business data associated with the travel property from the historical transaction data. The lost business data includes at least one of a regret or a denial. The profit optimization module forecasts a demand for bookings at the travel property on a day of arrival, wherein the demand for bookings is based on at least in part on the historical transaction data and the lost business data. In addition, the profit optimization module determines an offer price for a booking of a unit at the travel property, wherein the offer price is based on a capacity of the travel property and the forecasted demand for bookings at the travel property, and wherein the offer price is designed to increase a profit for the travel property."Share this quote Big Data focusCofounders Bosworth and Marco Benvenuti previously worked at Wynn Resorts and other casino hotels, while co-founder Craig Weissman, was previously chief technology officer of Salesforce.com.The company says that, since its founding in 2012, it has signed "hundreds of properties and is currently deployed in 16 countries."
