Theoretically, it can be automatized by means of optimization techniques, although this is a challenging task. Previous studies have shown the ability of genetic algorithms to perform this task in several cases, although some limitations have been detected. In addition, gradient-based methods, although also presenting some limitations, have provided good solutions in other technical fields. For this reason, the performance of genetic algorithms and gradient-based methods in the correlation of TMMs is discussed in this paper to compare the pros and cons of them. The case of study used in the comparison is a real space instrument flown on board the International Space Station. %@ 1687-5966 %K Thermal Mathematical Model %K Space %K Correlation %K Model adjustment %K Optimization %K Gradient-Based solutions %K Genetic algorithms doi 10.1155/2017/7683457 %U http://hdl.handle.net/11556/406 %~ GOEDOC, SUB GOETTINGEN
