Abstract: Randomized experiments, or A/B testing, are the gold standard for evaluating interventions but are underutilized in the area of inventory management. This study addresses this gap by analyzing A/B testing strategies in multi-item, multi-period inventory systems with lost sales and capacity constraints. We examine switchback experiments, item-level randomization, pairwise randomization, and staggered rollouts, analyzing their biases theoretically and comparing them through numerical experiments. Our findings provide actionable guidance for selecting experimental designs across various contexts in inventory management.
