摘　　要： 针对当前牛鞭效应研究集中于产品供应链的现状,以及服务的无形性等众多与产品不同的特性,提出以服务能力模拟产品库存进行牛鞭效应研究的可能;构建了物流服务供应链的概念模型,归纳出其牛鞭效应的四个成因;以上下游服务能力调配策略为基础,构造了三阶物流服务供应链中的成本函数和等待时间函数,运用仿真软件Anylogic进行了实证分析和优化改进。结果表明牛鞭效应确实也存在于服务型供应链中,造成能力利用率偏低和资源浪费,同时验证了以服务能力模拟产品库存进行牛鞭效应研究的有效性。 Considering the study of ＂bullwhip effect＂ is concentrated in product supply chain, and the characteristics of service differs from product, such as intangibility, the paper proposed the possibility to study bullwhip effect by simulating product inventory as service capacity. Established the conception mode of LSSC, then proposed four root causes of bullwhip effect in LSSC. Structured the functions of cost and watting time in a three-stage LSSC based on the capacity allocation strategy between upstream and downstream. Used the simulation software Anylogic for empirical analysis and optimization. The result proves that bullwhip effect indeed exists in service supply chain, which causing the low capacity utilization and waste of resources. The experiment also shows the feasibility to study ＂bullwhip effect＂ by simulating product inventory, as service capacity.
