摘要：

Production line simulation is a prerequisite to ensure the correctness, rationality and effectiveness of a plan of the production design, and the simulation of the correctness of the production line logic is the most critical. To realize the production line simulation technology based on the digital twin, a method of digital twin logic model construction oriented to the production line simulation was proposed. First of all, the composition architecture of the production line simulation system was proposed. Then, the construction method of the digital twin logical model was explained from the four dimensions of geometry, physics, production behavior, and simulation rules. The definition methods of geometric attributes and physical attributes were introduced in detail, and the production behavior was defined by finite state machine and three types of simulation rules, which include messaging rules, synchronous advance rules and mutual exclusion priority rules. The production line logic simulation prototype system was developed based on the method of model construction finally, and the effectiveness of the modeling method was verified through the simulation of the production line example. © 2022, Editorial Department of CIMS.
