Abstract:

Focus on the product service supply chain which the demand of the product and the extend warranty service are affected by the product quality at the same time. The joint pricing strategy of the product price, the extend warranty service and the product quality are studied respectively with and without the quality constraint when the extended warranty service is provided by the retailers. The coordination contract is designed to reduce the double marginal effect under the decentralized decision. This paper analyzes the impact of the product price coefficient and the product quality constraints on the pricing of the product and the extended warranty service. The research shows that the quality constraints of the product is?crucial to prevent the manufacturer from lowers the quality based on self-interest. The coordination contracts can effectively reduce the price of the product, improve the product quality, and achieve the pareto improvement of the enterprise and the service supply chain system’s profit. The product quality coefficient and the product price coefficient will also affect the pricing strategy of the retailer’s product and the extended warranty service.
