Abstract: To explore the optimal extended warranty service business model for node enterprises and supply chain system,and to discuss the impact of channel power structure on selection of extended warranty service mode,a two-level supply chain model with extended warranty service consisted of one manufacturer and one retailer was constructed by using game theory.According to the four extended warranty modes existed in reality,the corresponding supply chain decision model with extended warranty service were built respectively.Through the equilibrium solutions and comparative analysis for the four decision models,the optimal extended warranty service business model was explored,and the effect of extended warranty service cost difference on optimal extended warranty service business modes for node enterprises was analyzed.Some example simulations were provided to prove the conclusions.

Key words: extended warranty, channel power, game theory, supply chains
