Abstract: Objective To establish the mathematical model for the team size of the space station astronauts and the model for the number of astronauts selected in a single batch,and thus provide theoretical reference for the establishment of astronaut selection strategy in China.Methods Based on the experience of astronaut selection and training and the features of space station mission,the mathematical models of astronaut team size and the number of astronauts selected in a single batch were established.Quantitative design was adopted to optimize and solve the multiple factors in astronaut selection and training,and then the selection strategies were put forward according to the solution.Results The solutions of the team size model for the construction period and the operation period of the space station were 15 and 30 respectively.The number of astronaut in the existing two batches could not satisfy the needs of the construction period,and the minimum number selected in the third batch of astronaut was 11.The optimal solution of the operation period I of the space station was to select 7~8 astronauts every 6 years.Conclusion The model proposed in this paper could provide good reference for number and frequency of astronaut selection in the future.It was applied and verified in the selection of the third batch of astronauts.
