<p><P>PROBLEM TO BE SOLVED: To provide a production planning method and program, and a production planning system, capable of drafting an executable and efficient production plan. <P>SOLUTION: When reproducing the production plan, a work list is updated to reflect a result situation of work, and a resource is limited about the work wherein preparation work is already started (steps S1-S4). About the work not started at the time point of reissuance of the production plan, a preparation work completion possible date is set, and a next allocation candidate work list is produced (steps S5, S6). Until no next allocation candidate work is left (loop R1), the work having an earliest startable earliest date after the preparation work completion possible date is preferentially allocated from the next allocation candidate work list (loops R2, R3, and steps S11, 12), and the production plan obtained as the result is reissued (step S13). <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
