Abstract
A production plan is made for a production line for producing finished products from a raw material. Based on the stock number of works in respective process steps at a planning time, the number of works processed at the respective process steps up to the planning time is calculated as the current cumulated processed works of the respective process steps. The target of the stock number of works in the respective process steps at a planned time following a passage of a plan period is calculated based on a target production representing the number of finished products outputted up to the planned time and an average cycle time of production from the raw material to finished products. The target cumulated processed works of the respective process steps at the planned time is calculated based on the target of the stock number of works in the respective process steps. The number of works necessary to be processed in the respective process steps during a period from a planning time to a planned time is calculated, as a process step load of the respective process steps, based on the current cumulated processed works of the respective process steps at the planning time and the target of the total number of the respective process steps at the planned time.
