Optimization of High-dimensional Simulation Models Using Synthetic Data

Authors: Thomas Bartz-Beielstein, Eva Bartz, Frederik Rehbach, Olaf Mersmann

arXiv

Simulation models are valuable tools for resource usage estimation and capacity planning. In many situations, reliable data is not available. We introduce the BuB simulator, which requires only the sp...
