<p><P>PROBLEM TO BE SOLVED: To improve the productivity by suppress the centralization of stay lots, thereby shortening a lead time or suppressing facility operation loss in the manufacturing of an electronic device. <P>SOLUTION: A production management system for managing the manufacturing process of an electronic device is provided with a progression plan correction coefficient arithmetic part for calculating the correction coefficientαof a progression plan by lots; and a progression plan making part for correcting the progression plan of each lot based on the correction coefficientα. This correction coefficientαis calculated, based on an arrival scheduled time T(k) to a progress k of the manufacturing process of each lot, existing in a production line at a certain T and the operation information of a facility x configuring the manufacturing process and a facility halt completion time Tc(x). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
