Abstract:

Discrete manufacturing is common in aircraft, ships, electronic equipment, automobile and other manufacturing industries. To ensure the correctness and flexibility of the modeling and simulation process of discrete manufacturing workshops, a logical modeling and simulation method for the production process of discrete manufacturing workshop is proposed. Based on the theory of discrete event dynamic systems and finite-state machines, the attributes and behaviors of the key elements of the discrete manufacturing workshop are abstracted into a unified logic model, and the function of various elements are realized through inheritance. A production process simulation algorithm is designed for the unified model and a two-dimensional graphical logical model and simulation prototype system is developed. An automobile painting workshop is taken as the example and the experiment is compared with the commercial software Plant-Simulation. The results show that the proposed method is effective and feasible and has reference value and significance for the simulation of the production process of the discrete manufacturing industry.
