Abstract

Unexpected disruptions, such as delays of manufacturing processes, addition of emergent jobs and failures in manufacturing equipment, often occur in the actual manufacturing systems, and a predetermined production schedule may not satisfy given constraints due to the disruptions in the manufacturing systems. This research proposed a new reactive scheduling method using the co-evolutionary genetic algorithm. The proposed method alternately modifies the loading sequences of jobs and the machining sequences of jobs in a very short time, in order to improve the disturbed production schedules without interrupting the progress of manufacturing process. A prototype of an extended reactive scheduling system is developed to evaluate the effectiveness of the proposed method. Some computational experiments are carried out for unexpected delays of manufacturing processes.
