Abstract
The current trends of environemnt benign production and rising energy price compel industries to improve energy efficiency and saving not only for manufacturers but also service industries. This paper proposes a service energy efficiency model and an energy-aware scheduling method using an energy-block modeling for service production systems. The energy-block represents whole power profiles during one processing job and that is modelled as combined multiple rectangle energy pieces. Each production facility has specific energy consumption pattern for a processing job. The proposed model is based on the energy-block model concept proposed by the authors for manufacturing system to extend for applying service production systems. 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 a preliminary experiment with some cases of different combinations of blocks, and it is confirmed the balance of energy max peak and makespan.
