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.
