具有资源配置的供应链竞争动态模型

在供应链竞争的经济背景下,考虑由多条结构复杂并且异质的供应链构成的竞争模型。供应链在市场需求的推动下以自身利润最大化为决策标准,整合生产工序、分配企业内部资源。在资源有限以及产品无差异的条件下,通过市场链的定义分析了供应链之间的竞争方式;利用动态投影系统理论建立了供应链竞争的动态模型,刻画了供应链之间相互博弈的动态行为过程;进一步,在单调性条件下分析了模型均衡解的稳定性条件。最后,通过数值算例验证了模型的合理性。

Dynamic Model of Supply Chain Competition with Resource Allocation

Based on the economic background of supply chains competition,this paper studies a competition model of supply chain with heterogeneous supply network structure.Pulled by the market demand,supply chains strive to develop optimal strategies in terms of production process integration,resources allocation in maximizing their profit.Firstly,under the assumption of limited resources and homogeneous products,the model of supply chain competition is illustrated by the definition of market chains.And then,the theory of projected dynamical systems is used to establish the dynamic model of supply chain competition,which is able to depict the behavior of these supply chains.Furthermore,the stability of the dynamic model under the monotonic condition is also analyzed.Finally,a numerical example is given to show the rationality of this model.
