ABSTRACT:
In a method for determining an optimum scheduling in a computer-aided scheduling system the data associated with a schedule to be generated is previously stored in a memory data. A strategy decision table showing therein one or more scheduling strategies suitable for a plurality of the states in a scheduling process is prepared. An optimization definition table indicating degree of improvement precedence or precedence order of the scheduling strategies of the evaluation items, where degree of improvement precedence is defined as degree of improvement of evaluation value of he evaluation item in changing of the scheduled strategy, is prepared. A schedule is generated by repetition of selecting and executing the scheduling strategies by using the strategy decision table. The other schedules are generated by changing the scheduling strategy selected in the state of the scheduling process by using the optimization definition table. An optimum schedule having the best evaluation value is selected.
