Validated Inventory Optimization Framework for E-commerce: Data & Code

This dataset contains the data, figures, and code accompanying our validated inventory optimization framework for e-commerce. The framework optimizes the cycle service level (CSL) under a standard (Q,R) policy, balances holding, ordering, and shortage costs, and reports a U-shaped total cost curve with a minimum around 95% CSL (fill rate ≈ 99.8%). We provide both “policy-stable” sensitivity (CSL fixed at 95%) and “re-optimized” sensitivity (CSL re-optimized under ±20% parameter shifts), as well as pooling analyses (constrained vs. unconstrained) and transshipment opportunities.

本数据集收录了配套于我们经验证的电子商务库存优化框架的相关数据、图表与代码。该框架针对标准(Q,R)库存策略下的周期服务水平（Cycle Service Level，以下简称CSL）进行优化，平衡持有、订货与缺货三类成本，并可生成一条U型总成本曲线，其极小值点出现在CSL约95%处（订单满足率≈99.8%）。本数据集同时提供"策略稳定型"敏感性分析（将CSL固定为95%）与"重新优化型"敏感性分析（在参数±20%偏移的条件下重新优化CSL），此外还涵盖集中库存分析（约束与无约束两种场景）以及转运机会相关分析。
