摘要:

离散型制造常见于飞机、船舶、电子设备、汽车制造等行业,为保证离散制造车间建模与仿真过程的正确性和灵活性,提出了一种面向离散制造车间生产过程的逻辑建模与仿真方法。基于离散事件建模理论与有限状态机理论,将离散制造车间中关键元素的属性与行为抽象为统一形式化的逻辑模型,通过类继承的方式实现了各种元素的功能;设计了一种针对统一模型的生产过程仿真算法;开发了二维图形化的逻辑建模与仿真原型系统,以某汽车涂装生产车间为例,与商业软件Plant-Simulation开展实验对比。实验结果表明:该方法有效且可行,对离散制造行业生产过程模拟具有参考价值与意义。

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.
