The core materials knowledge needed in the accelerated design, development, and deployment of new and improved materials is most accessible when cast in the form of computationally low cost and reliable process-structure-property linkages. The main objective of the present lecture is to introduce the computational methods to analyze and predict the technological processes, chemical composition, microstructure and mechanical properties of magnesium and titanium components. Multicriteria Aid for Decision Making by Movable Limits (MADMML) is presented to determine the optimal combinations of control factors satisfying the requirements given beforehand by a decision maker. Moreover, models of regression analysis and parallel numeric modeling with artificial neural networks are proposed to optimize and predict the composition, technological processes and exploitation properties.
