基于Vensim的集群式供应链跨链库存应急合作

Across-chain inventory emergency cooperation in cluster supply chains based on Vensim

运用系统动力学方法,针对由两条单链多环节组成的集群式供应链,应用Vensim建模软件,建立基于竞合条件的集群式供应链跨链库存应急补充模型。通过Vensim模拟的结果,对跨链库存应急补充模型进行参数灵敏度分析和指标检验分析,结果表明,库存应急补充可以在库存不大量增加的前提下有效提高供应链的市场需求满足率。

Using the system dynamics approach, the paper estab-lished the duster supply chains across-chain inventory emergency replenishment model on the two-chain multi-stage cluster supply chains based on competition and cooperation by means of Vensim modeling software. It was found that inventory emergency replenishment will increase market demand satisfaction while in- ventories do not increase roughly through the results of Vensim simulation by analyzing parameters sensitivity and measure indicators of the model.
