主要成果/荣誉
1)2021 年国际NeurIPS ML2CO比赛Primal Task 冠军
2) 2018年为题为"可变动定价:综合航空公司定价和收入管理模式"的工作提交了初步专利申请,这是与Miju Ahn和谢尔盖 谢巴洛夫的联合工作。我们的模型和方法产生了非常好的收入改进(初略估算每年有上千万美元),这项申请旨在保护该知识产权。
3) 2016年10月在智利圣地亚哥举行的第56届Agifors年度研讨会上荣获最佳技术论文奖,题为"运营恢复管理的最新改进"。该奖项由所有与会者投票选出,他们喜欢论文的独创性和技术价值。
4) 2014年Informs Daniel H. Wagner 运营研究实践卓越奖入围者,获奖材料标题为"Airline Crew Augmentation: Decades of Improvements from Sabre." 评委们特别喜欢我们的论文中的模型和方法。因为它们与实际非常接近,而且在产品中已经实施,并证明为航空业节约了巨大的成本。
5) 1984年,我在中国全国高中数学竞赛中总排名第六。1984年在全国高中物理竞赛中,江西省名列第一。由于数学和物理竞赛成绩优秀,1985年直接保送北京大学。
