METHOD AND DEVICE FOR PREPARING SCHEDULE FOR REPEATED PRODUCTION LINE AND RECORDING MEDIUM WITH REPEATED PRODUCTION LINE SCHEDULE PREPARING PROGRAM RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To plan the repeated schedule of a job shop while designating the period by taking the repeated production of the job shop as object and automatically preparing a repeated schedule on a computer by using algorithm with which the shortest repeated period is calculated and algorithm with which the repeated schedule in a designation period is planned. SOLUTION: Data such as data about product and data about process are inputted from a data inputting part 10, a shortest period operating part 12 calculates the shortest period of an object problem and presents the shortest period to a user. A designation period designated by the user is inputted to a designation period inputting part 14 so that the repeated schedule of the designation period can be planned. A schedule allocation priority operating part 16 derives a priority to allocate a schedule to a product. A repeated schedule planning part 18 selects one among derived priorities, plans a repeated schedule and repeats this operation until scheduling results about all of the decided priorities are obtained.
