ABSTRACT:
For enabling a execute of work start scheduling based on individual lot attributes, a production controller controls includes a lot schedule managing section for managing a first work estimate schedule for each of lots existing in finite buffer facility groups continuous in a working procedure, a facility schedule managing section for managing an operation stopping estimate schedule and a second work estimate schedule for each of facilities of the continuous finite buffer facility groups, and a buffer schedule managing section for managing a utilization estimate schedule for each of the finite buffer facility groups. With reference to the first work estimate schedule, the operation stopping estimate schedule, the second work estimate schedule, and the utilization estimate schedule, a continuous process scheduling section carries out scheduling of the lots put in a continuous zone of the continuous finite buffer facility groups. With reference to the third work estimate schedule, a progress control section controls execution of the work relative to the lots arrived at the finite buffer facility groups.
