This paper studies the decisionmaking of the supplier and the retailer under random market demand when the retailer transfers the ordering right to the supplier. The speculations based on models respectively provide the decisions for retailers’ optimal pricing, suppliers’ optimal order and optimal wholesale price as well as the decision of supply chain’s optimal order and pricing under decentralized decisions. Through numerical analysis, the influence of random market risks on market demand and supply chain performance under the two circumstances is discussed. Further analysis indicates that when market risks are larger, supply chain performance can be improved if the retailers transfer the ordering right to the suppliers.
