Modelling product design is an engineering methodology for improving productivity during research and development, so that high quality products can be produced quickly and at low cost. The idea behind modelling product design is to improve the quality of a product to minimizing the effects without eliminating the causes. The method permit for both the product and process design stage to improve product manufacturability and reliability by making products insensitive to environmental conditions and component variation. This book aims to launch new directions of research in theoretical and experimental modelling graphic for industrial products, as a method of investigation of the static and dynamic on improving quality and reliability. Until now a lot of investigations found different solutions for the improvement of quality, but the problem of low design solution remain without solution yet.
