Evaluation of Energy Efficiency and Productivity in Scheduling by Using Physical Simulator

Abstract

Green manufacturing has been becoming more critical in response to changing a demand for manufacturing sustainability from lower carbonization to strict decarbonizaton. This paper extends our previous work on energy awareness in scheduling and investigates the relation between energy efficiency and productivity based on the physically measured data including power consumption and uncertainties that can be observed through the developed manufacturing physical simulator. It is also demonstrated, through physical scheduling simulations in a brute-force way, that our manufacturing simulator is capable of evaluating energy-efficient operations of manufacturing systems.
