Building a System Model Describing the Physical and Mechanical Properties of a Casting as Dependent on Composition of Raw Materials

The paper solves the problem of discovering the dependence of mechanical properties of a metal casting on the chemical composition of source materials by constructing a system of models for an object with many input and output variables. For this purpose, a system of models for output variables is constructed using the system technology based on the combinatorial GMDH algorithm. Such a system of models will allow simultaneously choosing the chemical composition of the raw material ensuring the specified mechanical properties.
