On Wednesday, 2021-04-21, Prof. Weili XUE [薛巍立] of Southeast University [东南大学] gave his invited talk "Operations Management under Consumer Choice Models with Multiple Purchases." The talk showed that the profit of a company can significantly be improved if they consider that customers may purchase more than one item of a given product and that the amount and product they purchase depends on the pricing and utility. Such considerations are important both in online sales as well as for brick-and-mortar stores. We are deeply thankful for this very nice and insightful talk and for the inspiring discussion thereafter. On the same day, we also hosted invited talks by Prof. Min LI [李敏] (Nanjing University) and Assoc. Prof. Vincent Chau (Southeast University).

On Wednesday, 2021-04-21, Associate Professor Dr. Vincent Chau of Southeast University [东南大学] gave his invited talk "Weighted Throughput Maximization with Calibrations." Scheduling is always an interesting and challenging field, where many important algorithms and novelties have emerged. Dr. Chao introduced algorithms with strong worst-case guarantees for the problem of scheduling both calibration and jobs to machines. This research applies to many scenarios, as many advanced production machinery needs to be calibrated regularly to ensure a high manufacturing quality. The talk was very well received by the audience and, for the third time today, a very nice discussion ensued. (Before this talk on the same day, we hosted two more invited talks by Prof. Min LI [李敏] of Nanjing University and by Prof. Weili XUE [薛巍立] of Southeast University).

Our team warmly congratulates Dr. Zijun Wu [吴自军博士] for his promotion to Full Professor [教授]. This promotion is the result of his outstanding research work, including, for instance, an article recently accepted and published online by the Operations Research journal. Together with his other publications and the funding obtained from National Natural Science Foundation of China (NSFC) [国家自然科学基金], Dr. Wu has made very important contributions to the construction of our institute. Congratulations, Zijun!

The Institute of Applied Optimization welcomes Associate Professor Dr. Jingneng Ni [倪敬能副教授] as a new member of our team. Before joining our institute, Dr. Ni has worked as a Specialized Course Teacher in the Department of Mathematics and Applied Statistics [数学与应用统计系] of our School of Artificial Intelligence and Big Data [人工智能与大数据学院] of our Hefei University [合肥学院]. Dr. Ni has obtained his Ph.D. in Management Science & Engineering [博士] from Business School [四川大学商学院] of Sichuan University [四川大学], Chengdu [成都市], Sichuan [四川省] in 2016. He is an expert in modeling and simultation, operations research, bi-level decision making, and uncertain information processing. He has applied these technologies highly successfully to water resource management, ecosystem engineering, protection, and restoration. Several of his studies concern the ecosystem of the Chao Lake [巢湖], one of the five largest fresh water lakes in China and located very near to our city Hefei.

We are very happy that Dr. Ni joined our team. We are looking forward to working together and to exploring synergies to our research on optimization and hydrological modeling.

Our team warmly congratulates Dr. Zhize Wu [吴志泽博士] for his promotion to Associate Professor [副教授]. This promotion is the result of his outstanding research work, which is documented in several high-quality papers, including two SCI-indexed papers in 2020 alone. Dr. Wu additionally co-supervises two graduate students and has made significant teaching contributions to our school. Congratulations, Zhize!
