Responsiveness-related trade-offs for sustainable operations in perishable goods supply chains
本研究用系统动力学模型分析易腐品供应链中补货策略、配置与产品易腐性如何交互影响经济、环境和社会可持续价值，发现没有一种补货策略始终最优，且静态保质期协议在动态条件下效果有限。
Perishable goods supply chains still require exploration concerning sustainability trade-offs related to supply chain responsiveness. To explore this gap, this work examines responsiveness-related trade-offs for sustainable operations in perishable goods supply chains. Using a system dynamics approach, we model how replenishment policies, supply chain configurations, and product perishability interact to shape sustainable value, meaning economic, environmental, and social dimensions of value. Building on a stock management and aging chain framework, extended with behavioural demand and perishability dynamics, the model captures feedback effects from customer perceptions, information transparency, and inventory policies. Our results highlight that no single replenishment policy consistently outperforms others; instead, performance is contingent on perishability, forecast uncertainty, and supply chain load. Moreover, the findings question the effectiveness of static shelf life agreements, such as fixed minimum life on receipt (MLOR), under dynamic conditions. From a theoretical perspective, the model presented in this work contributes by integrating behavioural adoption dynamics and perishability-induced value loss into a system dynamics framework. From a managerial standpoint, it highlights the importance of aligning replenishment policies with demand profiles and transparency efforts, particularly in the context of sustainable operations.
