Energy Efficiency Management through Production Scheduling Using FlexSim Simulation and Integration of Renewable Energy Sources

Abstract. The article presents a methodology for managing energy consumption and scheduling production processes using discrete-event simulation in FlexSim combined with the Flexon Helios energy module. The approach enables modeling of production flows, machine scheduling, and energy consumption analysis, taking into consideration renewable energy sources such as photovoltaic installations. A representative case study is presented, including energy-intensive processes such as thermal treatment and finishing operations, highlighting how scheduling tasks in alignment with available renewable energy can reduce grid energy consumption without affecting production throughput. The proposed methodology offers a practical framework suitable for various industrial processes, enabling improved energy efficiency and flexible production planning.
