A predetermined production schedule may be often disturbed, due to unscheduled disruptions, such as delays of manufacturing operations and failures in manufacturing equipment. A genetic algorithm based reactive scheduling method was proposed in the previous research, in order to modify and improve a disturbed initial production schedule without suspending the progress of manufacturing process. This paper deals with a new reactive scheduling method, which changes both loading sequences of jobs on each resource and machining sequences of each job simultaneously by using a co-evolutionary genetic algorithm. A prototype of integrated reactive scheduling system was developed to evaluate the effectiveness of the proposed method through some computational experiments.
