Concept design integrated system and constellation architecture exploration

The method of rapid architecture selection and concept design was further discussed. The elementary models of satellite constellation′s architecture selection and concept design combined with concept design process were introduced. Risk and uncertainty analysis were integrated into the models. The integrated system of satellite constellation concept design was realized by using system design optimization framework(SDOF). The design process of the integrated system was given. The satellite constellation architecture selection and concept design proceeded with the interactive, evolving and collaborative fashion. The concept design optimization could be executed automatically, and the operation of design task unit could be monitored and controlled. After the completion of satellite concept design optimization, the design report′s context and style could be tailored by the costumers. The example for the satellite constellation for observing the earth was presented and its optimal result was achieved by using the multi-island genetic algorithm. The result demonstrates the usefulness and validity of the system.
