Globalized Distributionally Robust Optimization

时间：2023年3月31日周五 14:00 — 15:30
地点：SD 308
报告人简介：王曙明，中国科学院大学经济与管理学院，教授，优青。主要从事鲁棒优化、随机规划研究及其在选址、物流与供应链管理、健康医疗管理等领域的应用。研究成果发表在Production and Operations Management, INFORMS Journal on Computing, Transportation Science, IISE Transactions, Naval Research Logistics等期刊。
报告摘要：We extend the notion of globalized robustness to consider distributional information beyond the support of the ambiguous probability distribution. Focusing on the type-1 Wasserstein distance, we show that the globalized distributionally robust counterpart has an insightful interpretation in terms of shadow price of globalized robustness, and it can be seamlessly integrated with many popular optimization models under uncertainty without incurring any extra computational cost.

Shall We Only Store Popular Products?

Warehouse Assortment Selection for E-Companies
时间：2023年3月31日周五 15:30 — 17:00
地点：SD 308
报告人简介：刘方，中国科学院大学经济与管理学院，副教授，海外优青。本科毕业于北京大学，博士毕业于杜克大学。主要研究兴趣：库存管理，机制设计和可持续运营等。研究成果发表在OR、MSOM、POM等顶级期刊。
报告摘要：This paper studies the single-warehouse assortment selection problem that aims to minimize the order fulfillment cost under the cardinality constraint. Two cost functions are proposed, and the problem is formulated as mixed integer linear programs to solve it. A simple heuristic called marginal choice indexing policy is proposed to store the most popular products, which is scalable to large-size problems.
