摘要
通过对TFT-LCD主要加工工艺和主要设备工厂布局的分析,提出了一种设备布局的优化分析算法。这种算法假设前后工序的设备间的到达关系为等概率分布,进而求得工序间的平均物流距离。工厂总的物流距离是各工序间平均物流距离的和。利用这种分析算法分析了农场型设备布局方案和中心走廊型设备布局方案,结论是:中心走廊型设备布局方案有更短的物流距离。
A optimization algorithm of TFT-LCD process equipment layout was advanced through the analysis of the process flows and the typical layout of TFT-LCD factories. This algorithm was based on the assumption of equivalent probability of arrivals between the equipment of contiguous processes, and the average distance of any contiguous processes was thereby obtained. The overall distance of TFT-LCD process was obtained by the sum of all average distances. With the proposed algorithm a comparison was made between the layout of a farm and that of a center aisle, reaching the conclusion that the latter has better performance.
