Capacity and demand information sharing in a supply chain with bilateral information asymmetry

In bilateral asymmetric information sharing, a retailer has private demand and a supplier private capacity information. We propose non-financial information-sharing mechanisms without power structure and examine analytically how one’s sharing affects the other’s sharing for cooperative, sequential sharing, and under risk aversion. We find that the retailer shares if demand is higher than a threshold. The supplier shares if capacity cost is within a range of upper and lower cost thresholds.
A decomposition approach for constrained inventory replenishment

We consider inventory allocation of multiple products, across a network of warehouses. We propose a multi-period, multi-product newsvendor formulation over a network of capacitated warehouses with depth constraints, minimizing the e-tailer’s shipment cost. The efficient algorithm we propose balances the tradeoff between overage and underage costs across periods. We establish its rate of convergence and in collaboration with a fashion e-tailer, we perform a study showing a cost reduction of 9%.
