We developed a method to calculate the optimum sales quota, incorporating estima- tions for the demand of various discount tickets and purchase behavior of passengers with the next-best-option when they were not able to buy their desired ticket. We conducted a trial sale by applying the calculated sales quota into the actual seat reservation system and confirmed that the method can increase revenues and facilitate decision-making for setting sales quotas. Keywords: yield management, discount ticket, revenue, sales quota, reserved seat 1. Introduction for most Japanese airline tickets are not fixed: their prices vary depending on past or forecast sales. The prices of In Japan, railway passengers are supposed to decrease discount tickets are set at several levels, each with a fixed due to population decline. Since railway operators have sales quota.
