Since data analysis for modern astronomy is getting more complicated than ever, effective information sharing among scientists and software engineers, and a distributed computing are important to compute large amount of data. In this study, a model construction and data analysis framework based on Model Driven Systems Engineering (MDSE) which makes it possible to effectively share information among project members are presented. Especially, we propose analytic framework based on a grey box modeling and least-square method used widely in data analysis. In particular, scientific theories and equations can be implemented as models of MDSE. In addition, proposed framework enables us to automatically generate effective machine codes from the models, which significantly reduces analysis efforts and development costs. Generated machine codes are computed by distributed processing technology based on MapReduce and GPGPU. As an example, proposed framework is applied to Japanese space astrometry project named Nano-JASMINE.
