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.122586198enginfo:eu-repo/semantics/openAccessjournal article10.1155/2017/7683457Thermal Mathematical ModelSpaceCorrelationModel adjustmentOptimizationGradient-Based solutionsGenetic algorithmsThermal Mathematical ModelSpaceCorrelationModel adjustmentOptimizationGradient-Based solutionsGenetic algorithmsAerospace Engineeringhttp://www.scopus.com/inward/record.url?scp=85021739915&partnerID=8YFLogxK
