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.
