【摘要】：交叉环单向循环搬运系统是柔性制造系统或物流系统的典型基本环节,在半导体晶圆制造自动化搬运系统中有着广泛的运用,其搬运效率的叠加往往决定着整个系统的效率。不同的调度规则影响着小车间的堵塞状况,进而影响了整个柔性制造系统的搬运效率。为了减少堵塞并提高系统效率,构建了交叉环单向循环搬运系统的数学模型并对系统进行仿真分析,比较了不同调度规则的优劣性,得出较优的调度规则。仿真显示:在工件处理时间相同时,顺序调度规则优于随机调度规则,在工件处理时间不同时,最短处理时间与顺序调度规则相结合能减少更多的堵塞且提高效率,实现系统优化。
[Abstract]:Cross ring unidirectional cycle handling system is a typical basic link of flexible manufacturing system or logistics system. It is widely used in semiconductor wafer manufacturing automatic handling system. The superposition of the handling efficiency often determines the efficiency of the whole system. Different scheduling rules affect the clogging of the small workshop. In order to reduce the blockage and improve the efficiency of the system, the mathematical model of the cross ring unidirectional cycle handling system is constructed and the system is simulated and analyzed. By comparing the advantages and disadvantages of different scheduling rules, the optimal scheduling rules are obtained. The simulation results show that the sequential scheduling rules are superior to the random scheduling rules when the processing time of the workpiece is the same, and the processing time of the workpiece is different. The combination of the shortest processing time and sequential scheduling rules can reduce more congestion, improve efficiency and achieve system optimization.
