The Re?Pli project is represented with a contribution at the 20th International Conference on Ope?ra?ti?onal Re?sea?rch. The 3conference will take place from September 25 to 27 2024 in Croatia and is organized by the Croatian Operational Research Society (CRORS).
In the stream "Multicriteria Decision Making under Sustainable Development Goals context", Sascha Burmeister presents the potential savings that can be achieved through flexible production planning and in conjunction with the use of energy storage systems.
Abstract (Englisch):
The use of renewable energies strengthens decarbonization strategies. To integrate volatile renewable sources, energy systems require grid expansion, storage capabilities, or flexible consumption. This study focuses on industries adjusting production to real-time energy markets, offering flexible consumption to the grid. Flexible production considers not only traditional goals like minimizing production time, but also minimizing energy costs and emissions, thereby enhancing the sustainability of businesses. However, existing research focuses on single goals, neglects the combination of makespan, energy costs, and emissions, or assumes constant or periodic tariffs instead of a dynamic energy market. We present a novel memetic NSGA-III to minimize makespan, energy cost, and emissions, integrating real energy market data, and allowing manufacturers to adapt consumption to current grid conditions. Evaluating it with benchmark instances from literature and real energy market data, we explore the trade-offs between objectives, showcasing potential savings in energy costs and emissions on estimated Pareto fronts.
