Robust product design on the basis of the optimization methods allows for the development of the robust quality
control methods which can be applied during manufacturing process and product operation stages. Such methods
enable increase the products reliability by the fault detection of the incipient or small faults before they cause serious
damage of the whole product. In practice one of the most frequently applied quality control method is based on the
comparison of the nominal parameters with the parameters of the controlled product. It is assumed that the product
is not faulty when the parameters of the controlled product are similar to the nominal one obtained during robust
parameters design stage. The concept of the above quality control method is depicted in
