Optimal and Order-optimal Gated Priority-based Greedy Policies for Two-layer Multi-item Order Fulfillment
Xi Chen, Yuze Chen, Ziyi Chen +1
We study how an e-commerce firm should make real-time fulfillment decisions in a two-layer distribution network when multi-item customer orders arrive sequentially and future deman…
Online Linear Programming with Replenishment
Yuze Chen, Yuan Zhou, Baichuan Mo +3
We study an online linear programming (OLP) model in which inventory is not provided upfront but instead arrives gradually through an exogenous stochastic replenishment process. Th…
AdaSwitch: An Adaptive Switching Meta-Algorithm for Learning-Augmented Bounded-Influence Problems
Xi Chen, Yuze Chen, Yuan Zhou
We study a class of multi-period online decision-making problems with sequence-based predictions, which may be generated by machine learning models but whose accuracy is not guaran…
A Minimax-MDP Framework with Future-imposed Conditions for Learning-augmented Problems
Xin Chen, Yuze Chen, Yuan Zhou
We study a class of sequential decision-making problems with augmented predictions, potentially provided by a machine learning algorithm. In this setting, the decision-maker receiv…
