Building an effective resilient supply chain system (RSCS) is critical and necessary to reduce the risk of supply chain disruptions in unexpected scenarios such as COVID-19 pandemic and trade wars. To overcome the impact of insufficient raw material supply on the supply chain in mass disruption scenarios, this study proposes a novel RSCS considering product design changes (PDC). An RSCS domain model is first developed from the perspective of PDC based on a general conceptual framework, i.e., function-context-behavior-principle-state-structure (FCBPSS), which can portray complex systems under unpredictable situations. Specifically, the interaction among the structure, state and behavior of the infrastructure system and substance system is captured, and then a quantitative analysis of the change impact process is presented to evaluate the resilience of both the product and supply chain. Next, a case study is conducted to demonstrate the PDC strategy and to validate the feasibility and effectiveness of the RSCS domain model. The results show that the restructured RSCS based on the proposed strategy and model can remedy the huge losses caused by the unavailability of raw materials.

Omnichannel retail operations with ship-to-store and ship-from-store options under supply disruption

引用

Frontiers of Engineering Management 2023年第1期10卷 158-170页

作者： Yi HE Dexia HE Qingyun XU Guofang NAN School of Management Hainan UniversityHaikou 570228China School of Management Harbin Institute of TechnologyHarbin 150001China

Omnichannel retailing strategies are widely used in practice and have been extensively studied in recent years, but few studies have explored omnichannel retailing operations in response to supply disruption in the post-pandemic era. To fill this gap, this study explores whether the adoption of omnichannel fulfillment options (i.e., ship-from-store and ship-to-store options) can mitigate the risk of supply disruption in a supply chain where a retailer orders products from a reliable supplier and a risky supplier, respectively. Under the omnichannel retailing strategy, the retailer’s order quantity from the risky supplier may increase or decrease while that from the reliable supplier may increase. Interestingly, it is possible to achieve a win–win–win outcome when the supply disruption risk is high and the market share of the channel offered by the risky supplier is low. Moreover, the entire supply chain benefits from the omnichannel retailing strategy even if it faces a high level of disruption risk.

国际禁运联盟、供应链中断风险与我国宏观经济易损性

美国近期试图构建联盟以不断强化对我国的技术封锁，而芯片作为高科技的核心载体，是中美竞争的主战场。文章首次考虑美国构建对华禁运联盟背景下中国面临的芯片供应链中断风险，定量测算芯片进口中断对中国宏观经济的易损性及其影响边界。文章构建了全球13个区域、12个部门的动态可计算一般均衡模型，模拟不同芯片禁运联盟对世界主要经济体的经济冲击影响。研究发现：（1）美国单独实施芯片禁运对中国影响有限，但如果将韩国等经济体纳入其联盟中，中国经济将会遭受显著的负面冲击。（2）在芯片进口完全中断的极端情景下，中国当年实际GDP下降0.49%，出口减少8.02%，就业下降0.18%，失业人数增加约136.35万人。（3）受贸易转移效应影响，美国主导的对华芯片禁运联盟对联盟内外的经济影响具有显著的异质性，即联盟内部将会受损，联盟外部将会受益。（4）芯片禁运联盟对其内部成员的经济影响也具有显著的非对称性，如果韩国等经济体加入该联盟，其遭受的经济和就业损失将显著高于美国。（5）中国对芯片产业的补贴政策有助于减轻美国芯片禁运对国内经济造成的负面影响。文章首次揭示了芯片进口中断对中国经济的影响边界，为中国应对美国的高科技打压提供决策参考。
