Decentralized energy supply systems (DESS) are highly integrated and complex systems designed to meet time-varying energy demands, e.g., heating, cooling, and electricity. The synthesis problem of DESS addresses combining various types of energy conversion units, choosing their sizing and operations to maximize an objective function, e.g., the net present value. In practice, investment costs an...

In a highly competitive scenario, suppliers play a vital role in making a business organization successful. Business of any organization is continuous process and therefore the supplier selection is also dynamic in nature. This is quite natural as the organization’s demand; supplier’s capacity, quality level, lead time, unit part cost and fixed transportation cost of supplier varies with time. ...

The global optimization of mixed integer non-linear problems (MINLP), constitutes a major area of research in many engineering applications. In this work, a comparison is made between an algorithm based on Simulated Annealing (M-SIMPSA) and two Evolutionary Algorithms: Genetic Algorithms (GAs) and Evolution Strategies (ESs). Results concerning the handling of constraints, through penalty functi...

Sixth-Generation (6G)-based Internet of Everything applications (e.g. autonomous driving cars) have witnessed a remarkable interest. Autonomous cars using federated learning (FL) has the ability to enable different smart services. Although FL implements distributed machine model training without requirement move data devices centralized server, it its own implementation challenges such as robus...

Hydrogen network management has economic appeal due to its importance in oil refineries. It become genuinely relevant the restrictions of sulfur content fuels, which need hydrogen be removed. Mathematical programming can used as a tool for optimizing networks, and efficient within refineries achieved through material balance units that make up network. In this work, an optimization model Mixed-...
