Toward an optimal QCDE in manufacturing by health monitoring of equipment energy consumption

Japanese government has limited CO₂ emissions and energy consumption for enterprises for these years. Especially, Japanese manufacturing industry have to fight to reduce energy consumption because they consumes a large amount of energy. Meanwhile, productivity must be kept when reducing energy consumption in manufacturing. The paper proposes the method of health monitoring with considering transparent productivity for QCDE optimization in manufacturing process. QCDE stand for Quality, Cost, Delivery, and Energy. he proposed method aims to reduce energy consumption without any QCD reduction by monitoring precise energy consumption of manufacturing equipment. Our proposed method quantifies operational condition of equipments by the energy consumption of equipments. The experimental results yielded that wasted energy consumption by the target equipment was extracted via monitoring its condition and energy consumption.
