USE OF THE METHOD OF GENETIC OPTIMIZATION FOR SOLVING PROBLEMS OF IDENTIFYING THE THERMOPHYSICAL PROPERTIES OF A MATERIAL

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
