基于系统动力学的供应链物流资金供求平衡

Blance of Supply and Demand of Logistic Funds in Supply Chain System based on System Dynamics

运用系统动力学原理,研究如何保障供应链系统资金供需平衡。系统动力学逻辑模型和数理方程表明,物流系统资金供求微扰时,其自组织特性可使系统物流资金达到供需平衡;当系统微扰累积成宏观波动时,系统自组织宏观进化达到物流资金供需平衡。供应链系统物流资金管理的集成绩效IAL>1时,则供应链系统物流资金管理的微扰可消除;而IAL<1时,则供应链系统自组织功能将使物流资金供需状态出现宏观态的高阶跃迁。

Based on system dynamic theory, studies were made on keeping the balance of supply-demand of funds in the supply chain system. System dynamic logic model and mathematical equations showed that when the logistic system experienced perturbation, a supply-demand blance could be achieved by the self- organization of the logistic system; when the perturbation accumulated into macro fluctuation, balance could be achieved by macro-evolutiion of the system self-organization. If the integrated performanced of logistic fund management in the supply chain IAL 〉 1 , the perturbation in logistic fund management of the supply chain could be eliminated ; if IAL 〈 1 , the self-organization of supply chain system would enable the sate of logistic fund supply-demand to undergo macro-higher-order transitions.
