Abstract: Owing to lack of accurate and real-time data for the service-oriented intelligent manufacturing and few mechanisms exist to tackle the dynamic and collaborative decision-making,a dynamic decision-making method of manufacturing resource based on digital twin was proposed.The framework of dynamic decision-making of manufacturing resource based on digital twin was established.Moreover,device digital twin including Cloud-Deployed Digital Twin and Edge-Deployed Digital Twin and product digital twin were proposed to provide the real-time and accurate decision-making data.A multi-party collaborative mechanism based on real-time multi-agent was designed,and the hierarchical timed colored Petri Net was employed to model and analyze some complex manufacturing tasks.Furthermore,the rank correlation analysis was introduced to obtain the comprehensive weight,and the reference ideal method was introduced to perform a comprehensive evaluation of manufacturing resource.The proposed approach of dynamic decision-making was applied to some aero-engine blade manufacturing factory.The feasibility and validity of the proposed decision-making method were verified by the experimental decision results.
