PURPOSE:To caluculate directly a production planning on a lower level without developing the process of a production planning on a host level in a process control system. CONSTITUTION:Process sequence and lead time as process information are stored in a process information storage part a 3a as cumulative lead time in compliance with process sequence and production planning of each process is directly developed by a process production planning calculation part 2 based on the production planning of an item production planning storage part 1. Thus the production planning of each process can be calculated without process development and the production planning of a host level can be reflected on the production planning of a lower level in a short time so as to process the production planning in a short time. |
