Various studies have discussed the coordination of product and supply chain design decisions for global supply chain management. However, the impact of currency exchange rate uncertainty on the selection of product architectures and their suppliers has not been sufficiently addressed. As a response, this study proposes a two-stage stochastic optimization model in which the first stage determines the product architecture, and the second stage identifies suppliers for the modules and components in an optimal fashion based on the product architecture and uncertain currency exchange rates. The overall objective of two-stage stochastic programming is to determine the optimal product architecture that minimizes the expected total supply chain cost over uncertain currency exchange rate scenarios. The proposed model is applied to a bicycle supply chain case study for three global marketplaces associated with multiple currency exchange rates. The results demonstrate that optimal product architecture and its suppliers should be varied based on currency exchange rates and their uncertain fluctuation levels. Also, a product architecture for the supply chain of each marketplace maintains its optimality in the total supply chain cost, up to a specific exchange rate. The findings show the importance of joint integration between product and supply chain design when considering currency exchange rates. Additionally, the benefit of stochastic modelling is demonstrated by comparing the solution quality of the model with its deterministic counterpart.

汇率波动下产品架构与供应链的整合

各种研究都讨论了全球供应链管理中产品和供应链设计决策的协调。但是,货币汇率不确定性对产品结构及其供应商选择的影响尚未得到充分解决。作为回应,本研究提出了一个两阶段随机优化模型,其中第一阶段确定产品架构,第二阶段根据产品架构和不确定的货币汇率以最优方式识别模块和组件的供应商。两阶段随机规划的总体目标是确定最佳产品架构,以在不确定的货币汇率情况下将预期的总供应链成本降至最低。所提出的模型被用于自行车供应链案例研究,该案例研究了与多种货币汇率相关的三个全球市场。结果表明,应根据货币汇率及其不确定的波动水平来改变最佳产品架构及其供应商。而且,每个市场的供应链的产品体系结构都可以在特定的汇率范围内保持其在整个供应链成本中的最优性。研究结果表明,在考虑货币汇率时,产品和供应链设计之间进行联合整合的重要性。此外,通过将模型的解决方案质量与其确定的对等物进行比较,可以证明随机建模的好处。结果表明,应根据货币汇率及其不确定的波动水平来改变最佳产品架构及其供应商。而且,每个市场的供应链的产品体系结构都可以在特定的汇率范围内保持其在整个供应链成本中的最优性。研究结果表明,在考虑货币汇率时,产品和供应链设计之间进行联合整合的重要性。此外,通过将模型的解决方案质量与其确定的对等物进行比较,可以证明随机建模的好处。结果表明,应根据货币汇率及其不确定的波动水平来改变最佳产品架构及其供应商。而且,每个市场的供应链的产品体系结构都可以在特定的汇率范围内保持其在整个供应链成本中的最优性。研究结果表明,在考虑货币汇率时,产品和供应链设计之间进行联合整合的重要性。此外,通过将模型的解决方案质量与其确定的对等物进行比较,可以证明随机建模的好处。每个市场的供应链的产品架构都可以在特定的汇率下在总供应链成本中保持最佳状态。研究结果表明,在考虑货币汇率时,产品和供应链设计之间进行联合整合的重要性。此外,通过将模型的解决方案质量与其确定的对等物进行比较,可以证明随机建模的好处。每个市场的供应链的产品架构都可以在特定的汇率下在总供应链成本中保持最佳状态。研究结果表明,在考虑货币汇率时,产品和供应链设计之间进行联合整合的重要性。此外,通过将模型的解决方案质量与其确定的对等物进行比较,可以证明随机建模的好处。
