摘要
针对汽车检测线运行效率评估及确保给定数量车辆检测时间最短的问题,通过分析检测过程中的驱动事件和状态演变,给出了车辆调度的约束条件,在此基础上把模型中的时间约束与受控Petri网相结合,提出了受控时间Petri网(Controlled Time Petri Nets)模型,采用该模型对检测线调度过程中的节拍控制与车辆调度进行可视化的建模与分析。实践表明对于多批次车辆检测任务采用该过程模型可明显缩短检测时间。
Focusing on the efficiency evaluation issue for vehicle testing systems,the driving events and the state transitions during the testing are analyzed,and the constraint conditions of vehicle scheduling are proposed as well.By combining the time constraint condition of scheduling and Controlled Petri Nets,a Controlled Time Petri Nets is proposed,and has been applying to modeling and analyzing of beat control and vehicle scheduling of vehicle testing system.It is demonstrated from the simulation results that the dynamic simulation based process model shorten the testing time compared with the traditional serial scheduling method.
