Flexible discrete-event system modelling and simulation platform design oriented to digital twin
Aiming at the challenge of creating digital twin models within highly flexible systems,a methodology for designing a flexible discrete event system modeling and simulation platform was proposed.The methodology initia-ted with a thorough analysis of requirements and proceeds to construct a logical model for platform design.Based on this logical model,a comprehensive platform design approach encompassing three critical aspects:simulation en-gine,flexible twin model modeling and visualization was presented.To facilitate seamless integration between the platform and digital twin models,a data interaction mechanism built upon the event advancement principles of physi-cal entity states and the optimization-oriented algorithm-driven step-by-step iteration process was introduced.To validate the effectiveness of the approach,a prototype platform named NextING was developed and conducted com-parative testing with commercial simulation software Plant Simulation.The efficiency of the proposed methodology was demonstrated through case studies involving an assembly production line and a robotic mobile fulfillment sys-tem.
