Unexpected disruptions often occur in the manufacturing systems. The manufacturing systems cannot execute the manufacturing operations in accordance with the predetermined production schedule due to such disruptions. Therefore, a systematic scheduling method is required to cope with such disruptions. In this research, distribution of processing time is described with the normal distribution. The reactive scheduling method for distribution of processing time is proposed in order to modify the predetermined production schedule. And the suitable re-scheduling period is considered through the computational experiments.
