English(EN) Regret Optimality of Sample Average Approximation for Data-Driven Newsvendor Problems: A General Optimization Perspective

新闻供应商问题分析推进SAA遗憾界限

作者 PulseAugur 编辑部 · [1 个来源] · 2026-07-21 04:00

本文提出了一种通用的方法来分析数据驱动的新闻供应商问题的样本平均近似（SAA）方法。作者将先前的工作从线性成本场景扩展到更一般的凸性条件，为顺序随机优化提供了统一的遗憾分析。该研究改进了上限和下限遗憾界限，确立了SAA的遗憾率最优性，并为评估数据驱动决策和库存管理中的新算法提供了基准。 AI

影响为数据驱动的决策算法提供了理论支持，有可能提高库存管理和其他优化任务的性能。

面向数据驱动的新闻供应商问题的样本平均近似的遗憾最优性：一个通用优化视角

arXiv:2407.04900v2 Announce Type: replace Abstract: Numerous existing studies have examined the performance of Sample Average Approximation (SAA) in the fundamental newsvendor problem. Despite these advances, critical gaps remain in two aspects. First, existing works focus on the…
