A Basic Study on Scheduling Method for Electric Power Saving of Production Machine

At present, energy consumption all over the world is increasing, and various approaches to energy issues such as the Sustainable Development Goals (SDGs) are in progress. In Japanese manufacturing industry, the introduction of factory Energy Management System (EMS) and the improvement of production equipment are being carried out in order to reduce energy consumption. Accordingly similar considerations are also important issues for production scheduling. In this paper, based on the assumption that renewable energy and EMS will eventually be introduced in the future, we focus on factories and utility companies, and at the same time, try to realize a scheduling method that improves energy efficiency with keeping production performance, and evaluate it by computational experiments.
