Abstract:

To optimize the process of space science mission concurrent design, an approach based on the Design Structure Matrix (DSM) modeling and Genetic Algorithm (GA) optimization method is proposed. In this approach, main design activities and dependencies relationship between the activities during the process of space science mission concurrent design are analyzed, and then the DSM model of the process is established. The design activities sequence corresponding to the DSM is treated as the chromosome and is optimized by the GA method. The optimal goal is to reduce the iterative times and to improve the parallel extent. A practical example of space science mission shows that the proposed approach can be applied to modeling and optimization of the process for space science concurrent design.
