摘要: 生产/库存系统的稳定性是供应链管理中的重要指标.需求信息共享(DIS, Demand Information Sharing)机制已在管理实践中得到广泛的应用.但对DIS供应链系统稳定性的研究仍然非常有限.使用控制工程理论建立了一个两级DIS供应链系统模型,定量分析了系统的稳定性条件,给出了系统参数的取值范围,并通过仿真实验进行了验证.研究结果表明合理调整系统参数能够提高供应链系统的稳定性.在此基础上针对阶跃需求输入研究了系统参数对供应链系统中订单、库存和在制品动态响应的影响.揭示了供应链系统的动态特性,提出了供应链成员决策的管理建议.

Abstract: The stability of production/inventory control system is an important indicator in supply chain management, and demand information sharing (DIS) mechanism has been widely adapted in managerial section. However, research on DIS stability boundaries and conditions is by far very limited. Based on control engineering, a DIS two-echelon supply chain dynamic model was established. The stability boundary of the system parameters was derived analytically, and then verified by simulations. The results show that system stability can be improved by appropriate parameter settings. For stepwise customer demand input, the effects of system parameters to system dynamic responses including order rate, inventory level and work-in-process were analyzed. Valuable insights into dynamic behavior of supply chain systems are obtained, and then managerial strategies are proposed.
