研究基于一阶混杂Petri网模型的柔性制造系统粗糙控制.为构造正确的一阶混杂Petri网模型行为演变图,提出了确定改变Macro状态事件的新方法;进而给出了柔性制造系统优化与控制算法,并基于粗糙集合理论和所给出的算法,提出了柔性制造系统的粗糙控制方法.最后通过一个实例验证了该方法的有效性.
In this paper, the first-order hybrid Petri nets model based rough set control for flexible manufacturing systems is studied. In order to construct the correct evolution behavior of first-order hybrid Petri nets model, a new method to determine the change of macro state events is proposed. Then, the optimization and control of flexible manufacturing system Algorithm, and based on rough set theory and the given algorithm, a rough control method for flexible manufacturing system is proposed. Finally, an example is given to verify the effectiveness of the method.
