Abstract: Aiming at the problem that there is little local cooperative information used in cooperative co-evolution mechanism, by improving the cooperative co-evolution for Multi-Satellite TT&C Scheduling(MSTS), this paper emphasizes the local interaction function under global cooperation, proposes a performance index for individual——Local Interaction Value(LIV), which indicates its cooperative effectiveness with its neighbor populations, and takes LIV as one of the measures of individual quality in the selection operation. In order to improve the mutation self-adaptation, the difference between LIV and sum of all child fitness is taken to determine the mutation probability, which can reduce the phenomenon of losing excellent individuals due to the non-global characteristic of delegate individuals. Simulation result shows that it can improve the quality of solution.

Key words: Multi-Satellite TT&C Scheduling(MSTS), local interaction, co-evolution
