Abstract: A network structure of supply chain was focused including two manufacturers and two retailers, and a competition model of expected profit maximization was established to study production capacity competition between manufacturers, ordering and pricing competitions between retailers. Then, equilibrium policies were analyzed. Following conclusions were obtained under the condition that the demand was price sensitive. There exist the optimal pricing and ordering policies for the retailers. The optimal pricing policy for a retailer was influenced not only by the wholesale price, but also by the pricing of another retailer. The optimal price was increasing monotone with the wholesale price and another retail price. While the optimal order quantity was decreasing monotone with the wholesale price and another retail price. The manufacturers also have a set of optimal pricing policies and equilibrium competitive production policies. Finally, a numerical example was presented to analyze this competition model.
