The European H2021 KDT-JU project called HiConnects "Heterogeneous Integration for Connectivity and Sustainability" has completed its third year of activity. The University of Catania (UNICT) is one of the 64 European partners involved in the project (scientist: Prof. Antonio Costa), developing sustainable, energy-efficient, and universally accessible cloud and edge computing platforms. UNICT is working on the development of innovative methods for production scheduling at STMicroelectronics (ST-I). To date, UNICT has developed and tested two different digital twin frameworks in the cleaning-diffusion phases (Fig.1): i) the first based on a self-adaptive hybrid Harmony Search algorithm; ii) the second obtained by fusing clustering methods for the encoding phase and reinforcement learning algorithms for batch dispatching. The results obtained using company data confirmed the quality of the developed approaches, indicating average improvements in monthly productivity between 4% and 8%.
