Making Better Fulfillment Allocation Decisions on the Fly

Online retailers manage large distribution networks, holding inventory in multiple locations to serve geographically-dispersed customers with varying service requirements. What is the best way to fulfill each customer's order when customers have different service-time requirements? We partner with a company that sells products online to examine this question, by first comparing a myopic strategy with a perfect hindsight optimization for a set of orders to characterize the potential improvement gap. We then report on the development of a heuristic that makes fulfillment decisions by minimizing the sum of the immediate cost plus an estimate of future expected opportunity cost of the decision. These estimates are derived from the dual values of a transportation problem assuming deterministic demand. In our experiments, we find that we can capture around 40% of the opportunity gap, leading to improvements on the order of 1%.
