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.
