Abstract: A production/manufacturing planning system is provided with a production planning planner 10 and a manufacturing planning scheduler 12. The production planning planner 10 makes the production planning for the whole factory, and the manufacturing planing sheduler 12 makes the manufacturing planning schedule for each of manufacturing lines on the basis of the production planning for the whole factory. Thus, it is possible to more precisely make the production planning and manufacturing planning than that in conventional systems.

Abstract: A production scheduling management system includes: a long-range production scheduling unit that receives long-range production scheduling information including at least information on a delivery date of each lot, produces a lot processing schedule based on the delivery date of each lot, and outputs a long-range production schedule; a short-range production scheduling unit that receives the long-range production schedule and short-range production scheduling information, produces a short-range schedule of lot processing so as to fulfill the long-range production schedule, and outputs a short-range production schedule; and a work scheduling unit that receives the short-range production schedule and work scheduling information, produces a work schedule so as to fulfill the short-range production schedule, while taking account of conditions of each machine and conditions of each lot, and generates work schedule.
