报告题目:系统思维下的国家物流枢纽

报告时间20251223日(周二)1830-1930

主讲嘉宾:赵林度

内容简介:截至20257月,国家物流枢纽总数增至181个,基本形成覆盖全国的物流枢纽网络,实现对地区生产总值4000亿元以上城市的基本覆盖和有效辐射。国家物流枢纽作为重要的基础设施,在增强产业链供应链韧性、推动区域经济发展、提升双循环能力等方面究竟应该发挥怎样的作用,报告将结合物流时间价值和物流空间价值等系统思维思想,阐述国家物流枢纽建设的重要意义。

报告题目Meal Deliveries with Ad-Hoc Drivers: A Distributionally Robust Contextual Optimization Approach

报告时间:20251223日(周二)1930-2030

主讲嘉宾:章宇

内容简介Meal delivery with a mix of in-house and ad-hoc drivers has been prevalent in recent years, in which the workforce constitutes about 30%-60% of the total expenses. In this work, we study a tactical workforce planning problem to minimize the total costs for meal delivery platforms. This problem determines the number of in-house drivers to hire as tactical-level decisions, who would fulfill the uncertain and feature dependent customer orders together with ad-hoc drivers in the subsequent operational phase. The objective is to minimize the sum of fixed costs for hiring in-house drivers, variable costs for delivering goods by both in-house and ad-hoc drivers, and penalty costs for unfulfilled orders. We account for uncertain customer orders and availability of ad-hoc drivers, which are affected by uncertain contextual feature information such as weather. To address the challenges caused by the complex interplay of in-house and ad-hoc drivers, the feature-dependent uncertainty and the limited historical data, we propose a two-stage distributionally robust contextual optimization (DRCO) model. We reveal a hidden network flow structure for the operational-level delivery problem, which enables us to relax the integer decision variables to continuous ones and further allows us to propose a Benders decomposition algorithm to solve the DRCO. Our numerical tests based on real-world data demonstrate the effectiveness and efficiency of the proposed models and algorithms.
