Abstract

The automated manufacturing systems are frequent within the modern manufacturing systems. This paper shows how the coloured Petri nets are used to assess a robotic manufacturing system, considering several versions of it. The system is made of three machines, and the workpieces are moved through the system by means of a conveyer-type transferring device. Three typed of workpieces are manufactured in this system. the modelling and simulation are made by means of coloured Petri nets. Within the first version, each workpiece type is manufactured on one machine. The loading and evacuation of the workpieces is made by means of an industrial robot for each machine. Within another version, a gantry-type robot serves all the three machines. Also, this paper analyses the case when the manufacturing of one workpiece is made on two machines. These versions were modelled by means of complex coloured Petri nets. The simulations were meant to point out any bottlenecks that may occur within the operation of the system. Using the time factor allowed to assess the system versions also for efficiency. Finally, the paper confirms that modelling and simulation with coloured Petri nets are very useful to assess the performances of the robot manufacturing systems.

通过具有复杂颜色和功能的彩色PETRI网建模的自动化制造系统

自动化制造系统在现代制造系统中是常见的。本文介绍了如何使用彩色Petri网来评估机器人制造系统，并考虑了它的几个版本。该系统由三台机器组成，工件通过传送带式传送装置在系统中移动。在这个系统中制造了三种类型的工件。利用彩色Petri网进行建模与仿真。在第一个版本中，每种工件类型都在一台机器上制造。工件的装载和排空是通过每台机器的工业机器人进行的。在另一个版本中，龙门式机器人为所有三台机器提供服务。此外，本文还分析了在两台机器上制造一个工件的情况。这些版本是通过复杂的彩色Petri网建模的。模拟旨在指出系统运行中可能出现的任何瓶颈。使用允许的时间因子来评估系统版本的效率。最后，本文证实了彩色Petri网的建模和仿真对于评估机器人制造系统的性能是非常有用的。
