为了研究复杂环境影响下供应链系统各环节变更传播效应,提出了基于数字孪生的供应链系统多模型变更控制.首先,基于数字孪生原理提出双空间四层数字孪生供应链系统架构.其次,结合供应链系统结构特征构建供应链系统动力学模型,讨论模型变更传播效应,并针对复杂环境下的不确定参数,采用数字孪生相似对比法进行参数整定.第三,针对本文所建动力学模型,设计一种基于状态观测器输出的多模型变更控制器和变更规则,利用极小极大鲁棒控制理论给出了变更控制问题可解的充分条件.并采用此控制算法,提出了数字孪生多模型变更控制原理.最后仿真结果表明,相比传统多模型变更控制,基于数字孪生多模型变更控制更具有优越性.
Multi-Model Change Switching Control of Supply Chain System Based on Digital Twin in Complex Environment
To study the change propagation effect for each link of supply chain system under the influence of complex environ-ment,this paper proposes a multi-model change control of supply chain system based on digital twin.Firstly,based on the digital twin principle,a dual-space four-layer digital twin supply chain system architecture is proposed.Secondly,the dynamics model of supply chain system is constructed by combining the structural characteristics of supply chain system,discussing the model change propaga-tion effect,and adopting the digital twin similarity and comparison method to adjust the parameters for the uncertain parameters in the complex environment.Thirdly,for the dynamics model constructed in this paper,a multi-model change controller and change rule based on the state observer output are designed,and the sufficient conditions for the solvability of the change control problem are given by utilizing the theory of minimax-maximax robust control.And using this control algorithm,a digital twin multi-model change control principle is proposed.The final simulation results show that the digital twin-based multi-model change control is more superior than the traditional multi-model change control.
