The concept of maximizing revenue on negotiated deals found its way back to the hospitality industry. Marriott's original application of revenue management was limited to individual bookings, not groups or other negotiated deals. In 2007, Marriott introduced a "Group Price Optimizer" that used a competitive bid-response model to predict the probability of winning at any price point, thus providing accurate price guidance to the sales force. The initial system generated an incremental $46 million in profit. This led to an Honorable Mention for the Franz Edelman Award for Achievement in Operations Research and the Management Sciences in 2009.
