PRODUCTION SCHEDULE PLANNING SYSTEM AND USING METHOD THEREFOR AND IRON AND STEEL PRODUCTION SCHEDULE PLANNING SYSTEM AND USING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To realize the smoothing of the load of an equipment by displaying a chart indicating the production capacity of the equipment per a prescribed time unit on a display means by making the chart correspond to a chart indicating the production estimated quantity per the prescribed time unit and adjusting the production estimated quantity by watching the displayed contents. SOLUTION: A display device 12 makes the production capacity by the date for every equipment into a polygonal line graph based on the information fetched from a capacity storage device by the equipment 9 and a special material casting schedule storage device 10, makes the production quantity by the date into a bar graph by the information fetched from a rolling scheduled date assigning device 11 and displays the production capacity and the rolling estimated quantity for every equipment by making them correspond. Based on this displayed contents, the adjustment of rolling estimated quantity is performed based on the information from a received order predicting device 8 and a received order amount transferring device 7. The rolling required time by the date is calculated again and a rolling schedule is planned so that the load of each equipment may be smoothed by watching the display the rolling estimated quantity by the calculation result.
