20.500.12556/RUL-159887 The development of simulation and optimisation tools with an intuitive user interface to improve the operation of electric arc furnaces The paper presents a novel decision support system designed to improve the efficiency and effectiveness of decision-making for electric arc furnace (EAF) operators. The system integrates two primary tools: the EAF Simulator, which is based on advanced mechanistic models, and the EAF Optimiser, which uses data-driven models trained on historical data. These tools enable the simulation and optimisation of furnace settings in real time and provide operators with important insights. A key objective was to develop a user-friendly interface with the Siemens Insights Hub Cloud Service and Node-RED that enables interactive management and support. The interface allows operators to analyse and compare past and simulated batches by adjusting the input data and parameters, resulting in improved optimisation and reduced costs. In addition, the system focuses on the collection and pre-processing of input data for the simulator and optimiser and uses Message Queuing Telemetry Transport (MQTT)communication between the user interfaces and models to ensure seamless data exchange. The EAF Simulator uses a comprehensive mathematical model to simulate the complex dynamics of heat and mass transfer, while the EAF Optimiser uses a fuzzy logic-based approach to predict optimal energy consumption. The integration with Siemens Edge Streaming Analytics ensures robust data collection and real-time responsiveness. The dual-interface design improves user accessibility and operational flexibility. This system has significant potential to reduce energy consumption by up to 10% and melting times by up to 15%, improving the efficiency and sustainability of the entire process. electric arc furnace energy consumption process optimisation decision support system user interface cloud services Node-RED elektroobločna peč poraba energije optimizacija procesa sistem za podporo odločanju uporabniški vmesnik storitve v oblaku Node-RED true false true Angleški jezik Slovenski jezik Članek v reviji 2024-07-29 13:55:17 2024-07-29 13:55:23 2024-07-30 03:45:46 0000-00-00 00:00:00 2024 0 0 17 str. iss. 8, art. 508 Vol. 12 Avg. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.365.2:681.5 2075-1702 10.3390/machines12080508 203067395 machines-12-00508.pdf machines-12-00508.pdf 1 F290F0C6FCE2E7A95AC9A05F890B5D5D a5d50da67e5714327016e90bd305f139a9862b19f50b2fcdfed61264e9d2f4f1 8ae2a437-4da1-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188119 https://www.mdpi.com/2075-1702/12/8/508 1 532bfa92-4da1-11ef-8f74-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=188118 Fakulteta za elektrotehniko 0 0 0
