<p><P>PROBLEM TO BE SOLVED: To provide a production management system for executing lot trace if at all possible even when there is any section whose cross-reference is incomplete in log reception/payment result data in a production management system. <P>SOLUTION: When a lot trace request is inputted, a result data management part 25 checks whether or not the same request as the lot trace request exists in the past lot trace results stored in a lot trace result storing part 26. When it exists, the pertinent lot trace result is outputted. Otherwise, a data development part 23 executes lot trace processing based on the contents(lot reception/payment result data) of files 51 to 53 managed by a lot reception/payment result data management part 5. At that time, when there is any section whose string attachment is incomplete in the lot reception/payment result data, the lot trace is executed while the complete section is inferred. Then, the lot trace result and the lot trace request are stored so as to be made to correspond to each other in a lot trace result storing part 26. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
