摘要

In creating mathematical models of the functioning of complex technical systems, one may often face a multilevel hierarchy and structure of models. Such models, as a rule, include a large number of parameters characterizing the process being described. The determination of these parameters is often associated with significant difficulties or appears entirely impossible. This circumstance results from many factors: starting with the impossibility to conduct direct measurements to the complexity of practical use of calculation algorithms. The paper discusses a methodology developed to determine the thermophysical coefficients of a material based on a genetic method of optimization. The genetic method makes it possible to construct a simple and efficient algorithm of solving a coefficient inverse problem. The paper also presents the results of processing a model experiment on calculating heat capacity and thermal conductivity coefficients.
