Impact of Extended After-sale Service Guarantee on the Decision-making of Electronic Product Supply Chain

文章研究了延伸售后保证服务对电子产品供应链决策的影响,分析了三种不同"延伸售后保证服务"提供模式的最优决策问题,结果表明:当服务成本相同时,分散决策结构下,零售商提供延伸售后保证服务,能够降低零售价格和延伸售后保证服务价格,可以获得较高的经济效益与社会效益;无论是分散决策还是集中决策,延伸售后保证敏感系数对不同模式最优决策的影响是一致的,零售价格与批发价格是其增函数,供应链各成员的利润、延伸售后保证服务价格是其减函数;当集中决策时,无论是制造商还是零售商提供"延伸售后保证服务",集中决策有较低的零售价格,和更高的"延伸售后保证服务"价格,延伸售后服务成为系统利润增加的保证。

This paper studies the impact of extended after-sale service guarantee on the decision-making of electronic product sup-ply chain.It also analyzes the optimal decision-making of three different service patterns of＂extended after-sale service guarantee＂. The findings are as follows：（1 ）Under decentralized decision-making,provided that service costs are equal,retailers＇offering of ex-tended after-sale service guarantee can reduce both the retail price and the price of extended after-sale service guarantee,thus gai-ning higher economic and social benefits;（2）The impact of sensitivity coefficient of extended after-sale service guarantee on the op-timal decision-making in various modes is consistent under either decentralized or centralized decision -making.The retail and wholesale prices are its increasing function while its decreasing function is the profit of supply chain members and the service price of extended after-sale service guarantee;（3）Compared with decentralized decision-making,centralized decision-making results in lower retail price and higher service price of extended after-sale service guarantee,no matter the service is offered by the manufacturer or the retailer.Extended after-sale service guarantee becomes a warranty to ensure increased system profit.
