Cellular manufacturing systems are well known as flexible and reliable manufacturing systems for assembly processes. A suitable control method is required for the cellular manufacturing systems to keep the production capacity in the case where unforeseen changes, such as delays of assembly processes, occur during the progress of assembly processes. This research proposes a new method for dynamic production management in the cellular manufacturing systems. When delays of assembly processes occur in the cellular manufacturing systems, delayed production schedules are modified in real-time by changing initial task allocations for workers and orders of the allocated tasks in order to minimize the total tardiness of products. The proposed method considers learning levels of workers in the task allocation processes. The method allocates various tasks for untrained workers in order to enhance workers' capabilities and productivities in the case where the total tardiness is less than zero and the cellular manufacturing systems still have enough production capacities. A prototype of reallocation supporting system is developed to evaluate the effectiveness of the proposed method.
