A hybrid optimization process between an heuristic method and a direct search deterministic method is used. Input and output values of real systems are used and some mathematical expressions are formulated to be used as test and validation. The results are compared with traditional methods, analyzing the oscillations at the edges. The proposed method presents a feasible solution for experimental data analysis and extrapolation, with reduced mathematical expressions. / Este trabalho apresenta metodologia para construção e otimização de estruturas matemáticas que representem dados experimentais. É utilizado processo de otimização híbrido entre método heurístico e método determinístico de busca direta. São utilizados valores de entrada e saída de sistemas reais e são formuladas algumas expressões matemáticas para serem utilizadas como teste e validação. Os resultados são comparados com métodos tradicionais, analisando as oscilações nas bordas. O método proposto apresenta solução viável para análise de dados experimentais e extrapolação, com expressões matemáticas reduzidas.
