Abstract

The bullwhip effect widely exists in supply chains and shows its significance for the competitiveness of enterprises in supply chains. In this study, we analyze the bullwhip effect in two parallel supply chains with competing products, each one consisting of a supplier and a retailer. A model is detailed for measuring the bullwhip effect in which the demand of retailers follows a similar vector autoregressive model (VAR-like) process. The results show that the bullwhip effect can be characterized as a quadratic function of the standard deviation ratio. The impact of market competition on the bullwhip effect of the supply chain may have the opposite result, which depends on some parameters, including lead time and market competition in the parallel supply chain. The parameters have asymmetric influence on bullwhip effect. Compared with VAR(1) and AR(1) model, the empirical results show that our VAR(1)-like model is closer to reality. Furthermore, we discuss the conclusion of research and its inspiration for supply chain management.

两条平行供应链中的牛鞭效应、市场竞争和标准偏差率

牛鞭效应广泛存在于供应链中，对供应链中企业的竞争力具有重要影响。在本研究中，我们分析了两条具有竞争产品的平行供应链中的牛鞭效应，每条供应链都由一个供应商和一个零售商组成。在该模型中，零售商的需求遵循类似向量自回归模型（VAR-like）的过程。结果表明，牛鞭效应可以表征为标准偏差率的二次函数。市场竞争对供应链牛鞭效应的影响可能会产生相反的结果，这取决于一些参数，包括并行供应链中的提前期和市场竞争。这些参数对牛鞭效应的影响是不对称的。与 VAR(1) 模型和 AR(1) 模型相比，实证结果表明我们的类 VAR(1) 模型更接近现实。此外，我们还讨论了研究结论及其对供应链管理的启示。
