发明名称 PRODUCTION PLANNING METHOD
摘要 <p>PROBLEM TO BE SOLVED: To automatically lay an optimum plan and to lighten the burden on an operator by determining time information on a manufacture process of manufacture lots whose manufacture order is determined and generating a manufacture schedule, and deciding the manufacture schedule as a candidate for a production plan when it meet previously set evaluation standards. SOLUTION: A sequence casting set group is searched for a manufacture lot which can be arranged right after a schedule having been planned (S1). According to the order of the sequence casting set, the steel feed start time of a steel converter, the process start time of refinery facilities, and the process start time of sequence casting facilities are determined (S5). After the order of the sequence casting set and the process start times of the respective facilities are determined, the schedule is one candidate for the solution of a planning result (S6) on condition that they are within previously given permissible ranges (S6). When a predetermined specific number of candidates for the solution of the planning result are obtained (S7), an optimum planning result is selected out of the candidates for the solution of the planning result and used as a schedule result (S8).</p>
