从供应链管理的角度,使用博弈论对厂商向消费者提供产品和延保服务的三种模式构建模型,并引入延保服务吸引力指数进行分析。分析结果指出：当购买产品的消费者仅部分购买延保服务时,生产商始终愿意由零售商提供延保服务,而零售商需要权衡延保服务吸引力指数的关系,在模式M和R中选择合适的渠道模式;当购买产品的消费者全部购买延保服务时,生产商和零售商都需要权衡延保服务吸引力指数的关系,在模式M和R中选择合适的渠道模式;当供应链成员提供延保服务的吸引力指数相同时,相对于生产商提供延保服务,零售商提供延保服务的模式能为供应链成员赢得更多利润。

英文摘要：

From the perspective of supply chain management, game theory was used to construct models for three modes, by which manufacturers provided product and extended warranty services to consumers. And the extended warranty services desirability irldex was also introduced to analyze. Analysis results revealed that ： （1） Only part of consumers who purchased the product with the extended warranty services, the manufacturer was benefited when the extended warranty service was provided by the retailer. But the retailer had to balance the relation of the extended warranty services desirability index to choose the optimal mode between the M and R modes. （2） All consumers who purchased the product with the extended warranty services, both the manufacturer and the retailer had to balance the relation of the extended warranty services desirability index to choose the optimal mode. （3） When the extended warranty services desirability indexes were equal, retailer provided the extended warranty services could benefit both of manufacturer and retailer.
