Abstract
The current trends of rising energy price compel manufacturers to improve energy efficiency and saving. This paper proposes an energy-aware scheduling method using an energy-block modeling which considers combination of each machine's energy consumption pattern. The energy-block represents whole power profiles during one processing job and that is modelled as combined multiple rectangle energy pieces Each machine has specific energy consumption pattern for a processing job. This paper examines single objective to minimize total tardiness by changing the parameter of constraint of energy max peak. The proposed model is applied to an experiment with some cases of different combinations of blocks, and it is confirmed the balance of energy max peak and make span.
