<p><P>PROBLEM TO BE SOLVED: To realize stable operation in a production process without causing excessive production. <P>SOLUTION: A process managing method includes a step (S100) which stores a production variation process and a planned non-defective rate; a step (S112) which detects processes in process and the number in process for every lot; a step (S124) which computes the number of non-defective products for every lot based on the number of loadings for every lot and a rate different from the planned non-defective rate for the lots before the production variation process, and computes the number of non-defective products based on the loadings for every lot and the planned non-defective rate for the lots after the production variation process, and then computes a predicted number of non-defective products which is the total of the numbers of these non-defective products; and a step (S130) which computes the number of the loadings additionally loaded to the production process based on the predicted number of the non-defective products thus computed. <P>COPYRIGHT: (C)2004,JPO</p> |
