Advanced numerical prototyping methods in modern engineering applications

Numerical prototyping methods based on numerical simulations and optimization are nowadays a key success factor for cost effectively and timely development, manufacturing of competitive products and processes. The typical numerical prototyping procedures are based on a sequence of numerical simulations/experiments done in an iterative form in order to achieve usually sub-optimal designs. These experiments are usually selected according to the knowledge and experience of an engineer or defined according to experimentally orientated methodologies. The current paper describes part of our preliminary research results of numerical prototyping, specialty focusing on the optimized numerical DOE approach, which leads to substantial reduction of numerical experiments for the specified accuracy of the response surface model.
