The network information system is a military information network system
with evolution characteristics. Evolution is a process of replacement
between disorder and order, chaos and equilibrium. Given that the
concept of evolution originates from biological systems, in this
article, the evolution of network information architecture is analyzed
by genetic algorithms, and the network information architecture is
represented by chromosomes. Besides, the genetic algorithm is also
applied to find the optimal chromosome in the architecture space. The
evolutionary simulation is used to predict the optimal scheme of the
network information architecture and provide a reference for system
construction.
