Abstract本发明涉及一种解决改机问题的限定分配调度方法,具体针对半导体后段制造过程中出现的由于不同封装外型可选设备相同、加工材料不同或者工夹具不同而导致的改机现象或者换产现象。本发明包括:步骤1:初始化;步骤2:未分配设备集不为空,转到步骤3;未分配设备集为空,转到步骤4;步骤3:统计与加工条件δh相同的设备总计数量计算加工条件为δh的允许最大设备分配数量;步骤4:对是否满足公式(2)的情况分别考虑;步骤5:加工任务集为空,则结束本道工序的分配,进入下一道工序的分配;否则,返回到步骤2。本发明能够解决由于改机不合理而造成的时间、成本等代价的损失和设备利用不均衡问题;避免了改机频繁现象的发生;提高了设备整体利用率。
Other AbstractThe invention relates to a method for limiting distribution and scheduling for solving a machine changing problem, which particularly aims to a machine changing phenomenon or a changeover phenomenon existed in the post-segmental manufacturing process of a semiconductor since the different packaging appearances can select the same equipment and different processing materials or different clamping apparatuses. The method comprises the following steps of step 1: initialization step 2: turning to step 3 if the undistributed equipment set is not null turning to step 4 if the undistributed equipment set is null step 3: counting the total quantity of the equipment with the same processing condition delta h and calculating the allowable maximum equipment distribution quantity with the processing condition of delta h step 4: respectively considering the situations whether meet a formula (2) and step 5: ending the distribution of the procedure if the processing risk set is null, entering distribution of the next procedure, or, returning to the step 2. With the adoption of the method provided by the invention, the problems that the loss of time, cost and the like and unbalance utilization of the equipment caused by the unreasonable machine changing can be solved, the occurrence of frequent machine changing phenomena can be avoided and the overall utilization of the equipment can be improved.
