Abstract
This paper analyzes the pricing decisions of complementary products in a fuzzy supply chain with two manufacturers and one common retailer. Four pricing models, including centralized decision model, MS-Bertrand, RS-Bertrand and NG models, with consideration of different market power structures are adopted. Both the manufacturing cost and the customer demand for products are considered as fuzzy variables. Optimal decisions on prices are determined by using game theoretical approach for each model. Finally, a numerical example is solved to illustrate the effectiveness of each model.
