资源配置混杂Petri网的混杂系统生产过程动态调度

为了增强混杂生产过程应对突发事件的能力,以一种新的混杂Petri网(资源配置混杂Petri网)为研究模型,给出了相应的使能和激发规则.并在资源配置混杂Petri网建立的仿真模型的基础上,融入事件逻辑网和逻辑规划,提出一种适用于混杂系统动态生产调度建模和优化的方法.以典型的混杂生产过程为例,研究混杂系统生产过程建模及优化.研究结果表明,资源配置混杂Petri网模型描述能力强,能够有效描述混杂系统生产过程,所提出的动态调度方案切实有效.

Dynamic scheduling of production process of hybrid systems based on resource distribution in hybrid Petri nets

To enhance the ability of hybrid Petri nets in handling the emergence in production process, we define a new extended Petri net model called the resource distribution hybrid Petri net(RDHPN). The enabling and firing rules of transitions of the RDHPN are discussed. Combining the simulation model, the event logic net and logic programming models, we propose the modeling and optimizing method. The application to a typical hybrid system shows that the proposed formalism is effective in modeling and optimization.
